Tire cleaning
If possible, do not clean tires with a steam jet. If the steam jet nozzle is held close to the tire, the adjacent rubber layer will be destroyed within a few seconds, even when using cold water. For safety reasons, tires cleaned in this way must be replaced.
Tires that have been in contact with oil or grease for a long time should also be replaced. Tires in such places swell, but later return to their normal shape and look undamaged from the outside. The load-bearing capacity of such a tire is reduced.
Tire storage
Store tires in a dark, cool and dry place. Do not allow tires to come into contact with oil or grease.
Store tires stacked or mounted on rims in a garage or basement.
Before disassembling the wheel, increase the tire pressure slightly (0.3-0.5 bar).
For winter tires, it is advisable to use your own rims, since re-mounting on the same rims will ultimately prove more expensive.
Tire running-in
New tires have a very smooth outer surface. Therefore, new tires - this also applies to the spare tire - need to be run in. During this running in, the smooth outer surface becomes matte due to initial wear. When driving a car with new tires on a wet road, be especially careful.
Wheel balancing
Serial wheels are balanced at the factory. Wheel balancing is necessary to balance the uneven distribution of mass. When driving, unbalanced wheels cause vibrations and the car to yaw on the road. The steering wheel begins to vibrate at a high frequency. As a rule, such phenomena occur in a certain range of driving speeds, and they disappear when the speed increases or decreases. Unbalanced wheels can subsequently cause damage to the suspension joints, steering gear, and shock absorbers. Submit wheels for balancing every 20,000 km, as well as after each tire repair, since wear and repair change the distribution of mass by the volume of the wheel.
