Tire cleaning
Avoid cleaning tires with steam if possible. If the steam jet nozzle is brought too close to the tire, its rubber layer will be destroyed within a few seconds. Even if cold water is used. If a tire has been cleaned in this way for any reason, it should be replaced.
A tire that has been in contact with oil or thick grease for a long time should also be replaced. This leads to local swelling, which subsequently disappears. However, the load-bearing capacity of such a tire is reduced.
Tire storage
Tires should be stored in a cool, dark and dry place and should not come into contact with oil or thick grease.
Wheels should be stored horizontally or suspended by the rim in a garage or basement.
Before removing the wheel, it is necessary to inflate it to 0.3-0.5 bar.
Winter tires should be stored on their own rims, as remounting them is not cost-effective.
Tire running-in
New tires have a smooth surface. Therefore, they require running-in. This also applies to the spare tire. During the running-in process, the initial wear causes the tire surface to become rough.
For the first 300 km of driving you need to be especially careful with new tires on wet roads.
