If the vehicle is later to be fitted with tires or rims that differ from the tires or rims fitted at the factory, the following must be observed:
For technical reasons, discs from other vehicles may not be used in every case - under certain conditions, also not wheels from a vehicle of the same type!
Rims and bolts for wheels are aligned with each other in a constructive way!
Therefore, with each conversion to other disks (e.g. light alloy wheels or wheels with winter tires) it is necessary to use the wheel bolts included here for the appropriate length and hemispherical shape. The fixed landing of the wheels and the functioning of the brake system depend on this!
As a result of using tires and/or wheels that have not been approved by us - for use on your type of vehicle, traffic safety may be impaired.
If wheel covers are subsequently fitted, care must be taken to ensure that there is sufficient air supply to cool the brake system.
Are common
Check the tires from time to time for damage, remove foreign objects from the tire profile.
To prevent damage to tires and rims, drive over curbs or other similar obstacles slowly and at as obtuse an angle as possible
Protect tires from contact with oil, grease and fuel.
Replace lost valve dust caps as soon as possible.
If the wheels are to be removed, they must be marked beforehand so that the same direction of rotation can be maintained during reassembly.
Removed wheels or tires should be stored in a cool, dry and, if possible, dark place. Tires that are not mounted on a rim should be stored upright.
New tires
Initially, the new tires do not yet have optimal traction and must therefore last approximately 100 km "run in" at a moderate speed. It also increases tire life.
Tire wear
The service life of a set of tires mainly depends on the following factors:
Tire pressure
Too little or too much tire inflation pressure reduces the life of the set of tires and has an adverse effect on the vehicle's driving behavior.
At high speed for a long time, a tire with little pressure must create more lateral deformation work, while it heats up excessively. This can lead to tread stripping and even rupture of the tire. In addition, due to too little pressure, fuel consumption increases.
Therefore, the pressure should be checked twice a month, and also before every long trip, and do not forget about the spare tire. Always check air pressure with cold tires. Increased air pressure in hot tires must not be reduced. The tire inflation parameters are placed further down in the text, as well as on a sticker and on the left longitudinal part of the door between the door hinges.
In move
Fast cornering, rapid acceleration and rapid braking increase tire wear.
Wheel installation error
Incorrect installation of the running gear causes not only increased, mostly one-sided tire wear, but also has a negative effect on driving safety.
Sign of wear
At the bottom of the profile of the original set of tires, transverse to the direction of rotation are "wear indicators" 1.6 mm high - see picture. Depending on the product, these wear indicators are located 6-8 times through
equal spacing on the circumference of the tire. Tire sidewall markings (e.g. letters "TWI" or triangular symbols) indicate the location of the wear indicators.
With a residual profile of 1 mm - measured at any point in the tread - the permitted minimum profile depth will be reached.
Since worn tires at high speeds on wet roads no longer provide the required grip on the road surface and rather lead to "surface" car. It is recommended not to subject the tires to this much wear.
Wheel replacement
With varying degrees of wear of a set of tires, it is recommended to replace the front wheels with the rear ones. Due to this, the service life of all tires becomes approximately the same.
Under certain conditions, after changing the wheels, it is necessary to perform a new balancing of the front wheels - see below.
Tire change
For reasons of traffic safety, change the tires, if possible, not individually, but at least one by one. Tires with higher tread should always be fitted to the front wheels.
Match only radial tires of the same design, size and, if possible, the same tread pattern.
For safety reasons, every time a new tubeless tire is fitted, use a new rubber valve.
Using the camera in "tubeless" tires should be limited to exceptional cases. At the same time, it should be ensured that the air trapped between the chamber and the tire can escape through the valve.
Tire repairs require a very large amount of specialist knowledge and must be carried out by a specialist.
Performing wheel balancing
The front wheels of the new car are balanced. However, during the operation of the car, under the influence of various factors, an imbalance may appear, which becomes noticeable when driving.
Since imbalance also leads to increased wear of the steering system, wheel suspension and tires, the wheels should be re-balanced. In addition, the wheel must be re-balanced after fitting a new tire and after each tire repair.
Typical tread pattern for abnormal tire wear
1. Bilateral tread wear
Insufficient pressure leads to overheating of the tires due to severe tire deflection. In this case, the tread engages with the road surface only at the edges, which reduces the grip of the wheels with the road and the edges of the tire wear out a lot. This type of wear is dangerous due to the possibility of tire rupture due to overheating. Check pressure and restore to normal. Wrong camber angle (increased one-sided wear). Repair or replace suspension parts. Severe angular wear. Drive at a moderate speed!
2. Too high pressure
Too high tire pressure leads to increased wear in the central part of the tread pattern, in which the grip of the wheels with the road surface is reduced. When driving with such tires, shock loads on the wheel increase and there is a risk of sudden tire failure. Check pressure and restore to normal. If you had to pump up the tires to the maximum pressure in connection with the upcoming movement at high speed, or with the transportation of a large load, then do not forget to reduce the pressure to normal afterwards.
3. Uneven wear.
Uneven wear of the front wheels may be due to a violation of the angles of their installation. Wheel alignment can be checked and adjusted at almost all auto repair shops or garages for a reasonable fee. Incorrect wheel alignment. Repair or replace front suspension parts. Abnormal operation of the front suspension.
Repair or replace front suspension parts. Increased wheel imbalance. Balance the wheels. Incorrect wheel alignment. Adjust wheel alignment.
Attention! One-sided oblique tread wear, which indicates incorrect wheel alignment, is best detected by touch.
Wheel swap
Rotation is necessary for even tire wear. The manufacturer recommends the following change intervals:
- On vehicles with a 4x4 formula - every 5000 km.
- On other cars - every 10,000 km.
When changing wheels, check for even tire wear. Wear unevenness is usually caused by incorrect wheel alignment, tire pressure difference, wheel imbalance, hard braking.
Installation of winter tires and chains
When driving on snow and ice, winter tires and chains are recommended.
When driving on wet or dry roads, the grip of winter tires is worse than conventional tires.
The type and design of winter tires to be fitted must match the type and design of tires fitted to the vehicle. When installing studded tires, follow local regulations.
Installing winter tires
Winter tires must be fitted to all wheels to prevent uneven grip and loss of vehicle control. Store removed tires in a cool, dry place. When installing tires, keep the previously adopted order of their rearrangement. Warning. Tire pressure must be correct. Do not exceed the speed limit for winter tires.
Chain Rules
Install proper chain size according to local codes.
The chains on the front wheels should be as close as possible to the tire.
It is forbidden to wear chains on the rear wheels. After advancing 0.5-1 km, tighten the chains.
When putting on chains, follow the chain manufacturer's instructions. If the wheels have decorative trims, remove them to avoid damage by the chains.
Security measures
Maximum travel speed with chains 50 km/h (or must be as specified by the chain manufacturer, whichever speed is lower).
When driving, avoid sharp turns and collisions with potholes, otherwise the vehicle may be thrown out of the rut.
