Ural motorcycle wheels. Ural tire size

Wheels of the Ural motorcycle
At IMZ, the Ural motorcycle is equipped with four identical wheels. Three of them are working, one is a spare. The wheel consists of a tire (with a tube and rim tape), a rim, spokes and a hub (Fig. 1). The wheels of Ural road motorcycles use I-40 model tires measuring 3.75 X 19" (95×484 mm). Size 3.75" indicates the width of the tire, size 19" is the mounting diameter of the rim. If necessary, you can use covers 3.25 X 19", 3.0 X 19", however the latter can only be installed on the sidecar wheel of a Ural motorcycle. When using a 3.0 X 19" tire with a linear tread pattern on the sidecar wheel, the sidecar wheel guard becomes less clogged with dirt and the motorcycle's mud patency improves. Motorcycles use a rolled steel rim from tape and then a welded rim. It has holes for installing nipples and spokes.

The spokes are made of special wire with knurled threads and transmit not only radial load, but also torque. To increase the permissible value of the torque, the spokes are located at an angle to the radius - tangentially. The hub of the Ural motorcycle is a steel team. It consists of the hub itself and a stamped brake drum riveted to it. After the hub is assembled, the brake drum is machined to ensure the required size and to reduce radial runout. To prevent lubricant from leaking out, dust and moisture getting inside the hub on the left side, it is sealed with an oil seal installed in the nut. The right side of the hub faces the brake drum or final drive, so it is less susceptible to contamination and there is no need to install an oil seal. The wheel rotates on two tapered angular contact bearings, which are lubricated with LITOL-24 lubricant. Such bearings have a high load-bearing capacity, but require proper adjustment. If the bearings are not tightened enough and have increased play, then shock loads appear during operation, as a result of which the bearing raceways quickly become chipped and the spokes break off. If the bearings are “overtightened”, then due to increased friction they will overheat, the lubricant will leak out, which will lead to their rapid failure. As the wheel moves, friction between the tube and the tire occurs due to tire deformation. To reduce the friction force when assembling the tire, talc is poured inside the tire. It is extremely undesirable for foreign objects (for example, peeled carcass threads) to get inside the tire, which contribute to wear of the inner tube of the Ural motorcycle.

In order to increase the technical and economic performance of Ural vehicles, since June 2004, it has been envisaged to use adjustable pressure tires with improved characteristics, radial design 390R20 model O-65 produced by OJSC Omskshina and 390/95R20 KAMA-URAL produced by OJSC Nizhnekamskshina, instead diagonal tires 14.00-20 model OI-25, produced by these factories.

Cars on radial tires have, in comparison with diagonal tires, better speed performance, fuel efficiency, lower noise levels and greater wear resistance, with other qualities being equal. The tires have the same overall dimensions as diagonal ones; no modifications to the latter are required for installation on the car.

Tires for the Ural motorcycle

Classic Ural models are equipped with tires with tubes measuring 3.75x19 inches. However, motorcycles with and "Wolf") have different tires. So that tires do not have to be changed quickly, they need to be looked after. Maintenance consists of checking the pressure and regularly inspecting the surface for punctures and abrasions. The manufacturer advises maintaining pressure:

You should adhere to these indicators and this will increase the service life of the rubber. In order for the tires to wear out evenly, it is necessary to change the tires every 2,500 km of the motorcycle ride, as indicated in the instructions for the vehicle.

This was usually done in an era of shortages - today a motorcyclist can easily do without it, since buying the necessary tires is not a problem these days. For motorcycles used in rural areas, special rubber is created with an aggressive tread pattern and thick studs.

How to choose the right mud tires

It should be noted that motorbike tires have design features. Tires can be radial or bias-ply. In the second, the fibers are not located at right angles to the profile pattern in the center. These tires are suitable for bikes used on long trips.

Radial motorcycle tires have an “R” marking on the cord, diagonal tires have a “-” mark, and diagonal tires with a reinforced belt have a “B” marking. In addition, the disk size is indicated on the cord. The R17 says it's a 17-inch radial. To clarify the speed limit, tables are used. In them, a certain speed limit receives a separate letter.

Reinforced tires with a tube are marked “TT”, while tires without a tube are marked “TL”. To have an idea of ​​the speed, you should make out the inscription on the cord, for example, 150/70 B17 69N TL:

An experienced motorcyclist on such wheels will be able to travel almost anywhere, including:

Mud Terrain (M/T) class tires have a hard and rough tread. With mud tires you can not be afraid of off-road conditions, and even take part in races. Riding a motorcycle with mud tires requires experience. But you should not use them in cold weather, since a sudden start or the desire to perform a maneuver and quickly brake will lead to a skid.

How to put a car tire on a motorbike

The first thing you need to decide is which tire to install. If the choice falls towards a rather narrow tire, for example, from a Zaporozhets, then you will not need to expand the frame.

A wide wheel on the Ural requires complete disassembly of the frame into component elements and reassembly after welding of the most ideal solution. It is necessary to cook at a high electric current to guarantee a high-quality result.

To ensure that the wheels are positioned evenly, it is necessary to use clamps when welding. The ends of the pipes must be divided into two parts at the required angle, and when welding, insert elements from a thin tube must be laid.

Tire on a motorcycle

There is another option to convert a car wheel onto a motorbike by moving the cardan and using a gearbox. It can be built from plates (steel 10 mm), installing 4 housings for 304 bearings in it. Next, you need to make steel shafts from 12ХНЗА metal, making an allowance of 0.3 mm. Everything should be cleaned, sanded in the central part, and sprockets from the VAZ timing belt should be arranged.

It is important that the sprockets sit on their original keys and are supported on both sides by stop washers. Next you need to do the following:

Next, you need to take a chain from a VAZ car and make it shorter by measuring the actual size. It would be correct to install a locking mechanism on the chain.

Then you need to secure the gearbox to the plate so that the mounting area is quite rigid. If this is not done, it may tear off. If the gearbox is installed on a pendulum frame, it is important to ensure that its axis is symmetrical with the axis of the secondary shaft. For these manipulations, you can put a wide tire on the motorbike. If you can’t install it yourself, the right thing to do is contact a service station.

Rubber for the Ural today is available in large quantities for free sale. The main thing is not to buy a fake; you should always ask for certificates. High-quality tires are durable and wear-resistant, guaranteeing safety when driving a motorbike. Good wheels will ensure maneuverability and controllability, eliminating skidding and injuries on the road.

How to stud tires on a motorcycle

Over the course of four years of active winter recreation, I was able to try out many tire options. First of all, you should familiarize yourself with the factory options.

Factory options

Civil version

Excellent for driving in winter on regular highways and city roads, for which car studs are used. This option is durable and does not in any way affect the asphalt surface when driving. In most cases it is used on light enduro bikes, ATVs and scooters.

Such axles are not suitable for driving in areas where there are no roads.

Battle Spike

A professional type of trunnion used in rally racing or motocross. When choosing such tires, you should pay attention to the following points:

Homemade spike

This type of tire treatment is not allowed in official competitions other than speedway. Organizers of sports competitions do not want to risk the safety of participants.

Next, we should pay attention to budget options for studs, in particular, how to stud the tires yourself.

Fastening the needles to the outside of the wheel using screw-in factory studs (the cost of a set of studs for both wheels will be about 10,000 rubles), or using roofing screws with a hexagonal head (the cost of the entire set will be 1,500 rubles).

Roofing screws

One of the methods for studding rubber with your own hands is to use roofing screws. It makes it possible to do without constantly changing tires according to the seasons; you just need to remove/install the studs.

Such studs are suitable for motorcycle tires and bicycles; to screw them in from the inside with a high degree of frequency, thin self-tapping screws are used, suitable for a slotted Phillips screwdriver, with flat wide heads.

The cheapest option for studding rubber is to use self-tapping screws for studding. Spikes are installed only on the front cylinder, taking into account the lower force of influence on it, in contrast to the rear one.

This approach is suitable for skating on bare ice; on snow-covered ground, the wheels will be useless. When driving on hard surfaces (asphalt, stone), the studs wear out quickly.

To install the studs, follow these instructions:

RUBBER-CORD COVERS

WHEELS AND TIRES OF MOTORCYCLES “URAL”, “DNEPR”

WHEELS AND TIRES OF MOTORCYCLES “URAL”, “DNEPR”

The wheels of the Ural and Dnepr motorcycles are interchangeable. In Fig. 5.12 and 5 13 show disassembled wheels of the Dnepr and Ural motorcycles.

Wheels are repaired if there are cracks in the rim, if the brake drum and bearing bore are worn. Wheel maintenance comes down to timely washing and lubrication of bearings, adjusting them, monitoring spoke tension, monitoring and maintaining tire pressure. The knitting needles should be tensioned evenly and fairly tightly. The degree of tension of the spokes is determined by the sound. A sign of weak tension is a low sound tone.

The condition of the bearings in the wheel hub is checked by rotating the tightened axle and rocking it in the wheel. The axle should rotate easily without noticeable play, clicks or jams. When the wheel rotates, radial and lateral runout is permissible: for the wheel rim - no more than 2 mm; for a tire, the lateral runout is no more than 3mm, the radial runout is no more than 5mm.

Rice. 5.13. Wheel of motorcycles of the "Ural" series: 1 - wheel body with a steel hub and brake drum; 2 - thrust washer; 3,4 - right and left spacers; 5 — hub nut assembled with oil seal; 6 — spring and oil seal; 7 - nut; 8 — rim; 9,10 - axle of rear and front wheels; 11 — axle nut; 12 - nipple; 13 — knitting needles; 14 - wheel without tire

• WHAT ARE THE SIZES OF RIM AND TIRE?

The system for designating wheel and tire sizes in inches is still used today. The first number indicates the width of the tire profile when inflated (for the rim, the width). The second number shows the clear diameter of the tire (rim diameter).

The sizes of motorcycle tires are shown in the table.

• HOW TO INSTALL A NEW WHEEL RIM ON AN M67 MOTORCYCLE?

In order to install the spokes on the other side of the hub, you need to lift the rim and press firmly on the hub, recessing it as much as the spokes will allow. Then turn the wheel over and insert the spokes into every fourth hole as in the previous case, tighten the nipples.

Rice. 5.14. Assembling a Ural motorcycle wheel

HOW TO FACILITATE THE WHEEL ASSEMBLY PROCESS?

When replacing spokes, rim or hub, a simple device helps to assemble the wheel (Fig. 5.15, 5.16). The wheel needs to be placed on it, having first slightly adjusted it. Insert wheel hub 8 into the central hole and insert rear wheel axle 9 into it. Place washer 6 on the axle and secure with nut 5. Tighten wheel rim 2 with clamps 1 and tighten all spokes evenly, starting with the short ones. Assembly accuracy will be guaranteed, and little time is required.

Tires. Tire types and size designations

There are several ways to designate tire size.

This tire size means that the tire has a height of 1,200 mm;

The inner (landing) diameter of the wheel (disk) is 508 mm - the “landing” diameter of the tire on the disk, i.e. the inner size of the tire or the outer size of the rim.

Another way to indicate tire size:

1 260 — tire height in mm;

14.00 is the tire width in inches;

20 is the inner (landing) diameter of the tire on the disk, i.e. this is the inner size of the tire or the outer size of the rim in inches;

R - means a tire with a radial cord (radial tire design).

Also, the tire size may look like this:

This tire size means the following: the tire has a height of 1,260 mm;

profile height is 85% of the width (i.e. 425x0.85 = 361.25 mm) - with the same width, the higher this figure, the higher the tire will be and vice versa. Usually this value is simply called “profile”;

The inner (landing) diameter of the wheel (disk) is 21 inches - the “landing” diameter of the tire on the disk, i.e. the inner size of the tire or the outer size of the rim.

made using radial tire production technology (that’s right, R is not the radius of the tire, but the radial design of the tire).

On a note.

The rubber is intended for use on the rear wheel of the Ural motorbike and its subtypes on the road and off-road.

Are there winter tires for motorcycles?

Most motorcyclists in our latitudes have the concepts of “season” and “off-season”. The season lasts part of spring, summer and half of autumn (sometimes longer, sometimes less). Off-season is the cold time of year, when it is wet and slushy. Only endurists allow themselves to travel in winter - precisely thanks to winter tires.

What are winter tires for a motorcycle?

Unlike automobile tires, serial tires for snow and slush are much less common. It is an off-road tire with blunt spikes about a centimeter long fused into them. Serial motor tires are quite expensive and not every person who likes to throw dirt in the winter can afford it.

Therefore, most bikers stud their wheels themselves. The principle is the same - equipping the rubber with homemade spikes. After modification, the motorcycle becomes stable on ice and moderately snowy roads, can easily get out of a skid and reduces the risk of falls.

Winter tires without studs for motos also exist. This is an analogue of regular road or sports tires, which is particularly soft and easily heats up on the road. But they can be used in low temperatures only in the complete absence of snow or frost. Most often, such wheels are purchased for winter competitions on a clean, well-prepared asphalt track.

We stud the wheels ourselves

Serial studs for bikes are incredibly expensive. Therefore, the majority of riders who do not want to winterize their motors stud the wheels themselves. There are several ways to get winter tires:

MY MOTORCYCLE

“It’s better to buy one pair of good shoes than three pairs of bad ones.” Marlene Dietrich Marlene Dietrich

Now on the market there are a lot of options for tires in Ural sizes to suit any budget from brands such as Mitas, Pirelli, Metzeller and others. But they don't work well on a wheelchair. Why?.. Let's share our experience.

Choosing tires for a motorcycle is an extremely responsible matter! But many approach this casually: “Why bother with the Ural? The size fits, the manufacturer is reputable - well, great!” As a result, the tire behaves unstably on the asphalt, wears out in a couple of thousand, or even simply falls apart, does not support the weight of the motorcycle and sinks into the ground. When choosing tires, one size is not enough. It is necessary to take into account the conditions in which it will be used and the weight of the motorcycle. The stroller does not tilt when driving, so you need tires with a square profile, similar to automobile ones. It has a larger grip patch, which is important for a heavy vehicle, and it wears out evenly, and not just along the narrow central stripe. Another important factor is the tire load index. For a wheelchair user, experts recommend 70 or more, but categorically no less than 67. If the index is lower, then even new tires can fall apart on the move simply from overload.

The modern Ural plant is equipped with Duro HF308 (4.00-19) tires. They come from Taiwan, although they have a proud Spanish name (translated as “solid”, “reliable”). Vasily “PZ” described it as follows: “The tire is universal - it rides mediocre both on asphalt and on dirt, but not at all on mud.” Its profile is round and on a motorcycle with a sidecar it only works with the central part, but it lasts for quite a long time due to the fact that it is quite rigid (I have ridden about 9000 km on the rear wheel). But in the cold it stiffens and completely loses contact with the road. Its advantage is its carrying capacity. There are few tires of this size with a load index of 72P (up to 355 kg and up to 150 km/h). And relatively inexpensive. Apparently, for the plant there is a compromise option in the price/quality ratio (RUB 4,500*).

It is recommended to cut off these technological “spikes” on new tires!

St. Petersburg makes a wide range of different (from asphalt to motocross) and inexpensive tires. For the project, we settled on two options suitable specifically for the Ural with a sidecar - universal and off-road.

The first is the L-333 model (4.10-19) with a load index of 70L (up to 335 kg and up to 120 km/h). Its profile is close to square and the contact patch is noticeably larger than that of Duro. Moreover, it is soft, which is why it holds the road much better, and does not stiffen in the cold. A pronounced (but not “evil”) tread with sipes (thin slots) on checkers works great on any hard surface, in any weather and season, and even on an icy road (tested in both summer and winter in the Arctic and Norway). It studs well even with a cargo stud. L-333 is good for roads with any surface and not bad for off-road. And for winter travel there is no alternative. The only negative is that it wears out quite quickly (I covered about 7,000 km on the rear wheel, of which 20% was off-road).

For mud, the best option is “Petroshin” S-97 (4.25-19, index 71K) and L-96 (3.75-19, index 68R). “Ninety-seventh” was made specifically for the “Ural”. According to the factory classification, this is not a cross-country tire, but for difficult road conditions - it has more blocks that are extended along the wheel, and the sidecar profile is close to square, and under load it holds onto the road with all the blocks. Due to its softness, it is not very durable, but it does not stiffen in the cold and, if necessary, allows you to get to the dirt on the asphalt under your own power without much shaking. If your task is not to set a lap record, but to drag a heavy motorcycle on a bad road, mud or snow, then it is great. But it is better to use it on rowing wheels - rear and stroller. On the front wheel, due to the square profile, it turns hard and is difficult to get out of ruts. For this purpose, there is the L-96 tire with a purely cross-country round profile. It is noticeably narrower, and in addition to the main checkers, additional “fingers” stick out to the side, which help to cling to the edges of the track when you need to get out of it. The experience of winter events such as “Connecting Bear” and “Samovar-Treffen” shows that so far no better ratio has been invented. In addition, they stud perfectly. The price of each specified Petroshin model is 3,500 rubles.

From left to right: Duro HF308, “Petroshina” L-333 (studless and studded), “Petroshina” S-97 (studless and studded), Heidenau K37.

For people with tight wallets, there is also Heidenau K37 (4.00-19 71R). A well-known German tire manufacturer produces it specifically for the Ural with a sidecar at the behest of the largest distributor IMZ in Europe. Universal, but somewhat closer to enduronic. Square, with a good contact patch. It has three longitudinal rows of large checkers with wide grooves. According to the experience of the guys from TruMotor, it drives well on asphalt, on rocks and soil, and not bad in mud. Although it is quite rigid, and therefore more durable (according to the experience of Moscow uralists, it runs up to 12,000 km on the rear wheel). But due to its harshness, it becomes dull in winter. Therefore, Heidenau made its winter “replica” - K37 Silica, which contains a large proportion of silicon. If we talk about versatility, then it has no competitors. But the price is steep - 11,500 rubles.

SHIPOVKA

If you are going to drive in winter, then studding your tires is a must! On icy ruts, frozen rivers and other ice, this is difficult to overestimate. Experience shows that on a motorcycle without a drive, but with studs, you are guaranteed to go further than on a motorcycle with a drive, but without studs. If you wish, you can drive to the same “Shatun” under your own power and get on the track without changing tires. For winter rides on hard surfaces, it is not necessary to stud the stroller. But if you go somewhere that is not cleaned, then all three wheels should be studded.

From left to right: 1, 2, 3 – passenger autospike 8 mm; 4 – cargo autospike 9 mm; 5 – rally autospike 8 mm; 6 – rally autospike 9 mm; 7, 8, 9 – motocross 9 mm (spike base diameter).

With this problem, we turned to Alexey “Tweezers,” a cheerful endurist and specialist in studding motor tires. During the work, he explained some of the subtleties.

There are two stud options for a motorcycle: a motocross stud and a road stud. The body of the spike is made of steel, and the core, part of which protrudes from the body, is made of hard alloy. Cross - purely sporty, tall. The length of the core over the rubber is from 7 to 10 mm. But, of course, they are not suitable for asphalt - there is no grip on the surface; they are for pure ice, trampled snow, icy ruts and other off-road delights. Therefore, for winter driving with a predominance of public roads, they install a car, passenger or truck stud (the latter is stronger and thicker, usually it is placed in the drive wheel). It makes it possible to drive comfortably and safely in winter, both on and off asphalt (without fanaticism, of course!). Such a tire works in the contact patch with both the stud and the rubber, which provides sufficient grip on the road both on clean asphalt and on icy areas. The spike is selected individually, depending on the size of the checkers. There are a lot of options, but the most suitable size for motorcycle tires is: 6-20 mm body height (landing), 8-9 mm its diameter, 1-1.5 mm visible part of the carbide core. For my Petroshina, the best option turned out to be a passenger stud with a body diameter of 8 mm and a core of 1 mm, but for L-96 and L-333 - with a fit of 7 mm, and for S-97 - with a fit of 12 mm. Unlike cross spikes, a regular tenon can be planted without glue - there is no heavy load on it, since the protruding part does not exceed 2 mm.

They are installed with a special pneumatic gun. If you don’t mind your fingers, you can hammer it in yourself using a drill, sledgehammer, mandrel and “such-and-such a mother,” but it’s better to turn to a specialist.

“Some, out of poverty, tenon with construction dowels, while others screw in self-tapping screws,” says Alexey. - Yes, they work, but all this is for two or three trips, and then throw away the tires. For both, the sharp end quickly wears off and stops working. There are also screw-in studs with a hex head, but this is complete bullshit and only ruins the rubber. And, of course, all these options are absolutely not suitable for asphalt.”

characteristics (chamber size, wheel diameter), tuning

The Ural bicycle is one of the images of the USSR. Almost all the children of that time rode it. Perhaps even now someone has this Soviet bicycle lying around in their garage or in the village.

As for the history of this brand, Ural bikes have been manufactured since 1965. Then the Perm plant launched the production of reliable and unpretentious bikes that would be useful not only for ordinary walks, but also for traveling long distances. They almost immediately began to be popular. Its design was simple, and repairs did not take much time.

The Ural bicycle was more focused on the adult male population of the country, but the Perm plant did not forget about the other part of the population. Kama is another product of this company. This is a ladies' bike, which was lighter and more comfortable than the Ural. Teenagers who still could not cope with the Urals also rode the Kama.

Characteristics

Even before the start of production, a suitable geometry was calculated taking into account the anatomical features of the person. All Ural bikes were large with a frame height of 56 cm. The wheel diameter was 28 inches, which made it possible to operate the bike on smooth roads and off-road conditions. Although the tires were more suitable for driving on smooth roads. Some still found a solution to the problem and installed home-made wider tires and tubes on the rear wheel.

It had a rear brake hub installed, but some enthusiasts later installed rim brakes on their bikes.

If we talk about the equipment, then it was almost always standard. But still, sometimes it expanded, and reflectors, footrests, reinforced luggage racks and even first aid kits were installed on the bicycle.

Why did you love it?

First of all, the products of the Perm plant were convenient and unpretentious. The bottom bracket and bushings, the most frequently broken components of any bicycle, were easily repaired and replaced. This was greatly appreciated by the people of the Soviet Union. The Ural could be used to transport heavy loads and rides to a neighboring village. It should be noted that it was in rural areas that the Urals were in particular demand. The largest size suited almost all men and even some women.

Unfortunately, the reliability was counterbalanced by the very heavy weight of the bike - 16 kilograms. The fact is that the frame and other components of the bike were made of steel. A modern high-speed analogue can weigh only 6-7 kilograms.

Snatching a new Ural in the 70s was considered very prestigious. They could be given out as incentives at factories.

Urals in the hands of enthusiasts today

Ural bicycles in the form in which they were almost 50 years ago are no longer produced today. However, not all of them have already rotted or are lying around in the attic as trash. Today, Ural bike tuning is quite popular. Some manage to change his appearance beyond recognition, while others simply restore his canonical appearance. Modernization is great and covers all its components. The most talented ones also equipped them with motors from mopeds and even chainsaws.

Some install analogue parts, while others diligently and painstakingly restore old ones. It is very difficult to find new parts for Urals today. You can basically buy them only from hand.

On the official website of the manufacturer you can find only 4 models of the Ural bicycle: 2 for women and 2 for men. They have completely identical characteristics with the exception of one thing: the women's bike has the corresponding geometry. All of them are produced on 28 wheels, with baskets on the handlebars, and high-speed ones are equipped with 6 gears with a Shimano shifter.

In addition to the Urals, the plant in Perm also produces components for bicycles of other domestic brands, for example, Stinger.

Bicycles Ural is a truly legendary bicycle in the history of Russia and the USSR. One of the few that has gained such popularity among all residents of the country. At one time it was almost a universal means of transportation: it was a road bike, a mountain bike, and even a sports bike. It all depended on whose hands it fell into.

The conversion of these bikes deserves special attention. In the skillful hands of bicycle masters, it turned into a real work of art. Currently, under the Ural brand, they produce only 4 bicycles, which are not used and are unlikely to become as popular as the older model.

Mud tires for a car made from old tires

Snow chains are often used when driving off-road (sometimes they are installed in winter if there are no studs). However, there is a more budget-friendly option - “shoes” made from an old tire.

The tire size for such a device must be selected individually; there are no universal sizes. However, you can use a tire of the same diameter as the wheel itself.

Or you can take a size larger (in this case it will be easier to put on). For example, if you have wheels 1757013, then you can put tires 1756514 on them.

When using such cheap “shoes” (the necessary tires can be purchased at any tire shop), you get budget “mud tires” that will help improve the cross-country ability of four-wheel drive vehicles. Yes, it is also suitable for all-wheel drive vehicles as an alternative to snow chains.
