Tire cleaning
If possible, do not clean tires with a steamer. If you hold the nozzle with a stream of steam near the tire, the rubber layer will be destroyed within a few seconds, especially after subsequent treatment with cold water. For safety reasons, a tire cleaned in this way should be replaced.
A tire that has been in contact with oil or grease for a long time should also be replaced. The tire at the appropriate place first swells, but then takes its original shape and looks like it has no damage. However, the load-bearing capacity of the tire is reduced.
Tire storage
Tires should be stored in a cool, dark and dry place. They should also not come into contact with oil or grease.
Tires should be stored in a garage or basement, lying down or mounted on a rim.
Before removing the wheels, you should increase the tire pressure slightly (by about 0.3-0.5 bar).
For tires with a winter tread pattern, you should use your own rims, since remounting tires on the same rims is not economically viable.
Safety instructions: Tires that are more than six years old should only be used as a last resort and with careful driving. When replacing or removing tubeless tires, the valve with a rubberized body must be replaced.
Tire running-in
New tires have a very smooth surface from the moment they are manufactured. Therefore, new tires (this also applies to the spare tire) are subject to running-in. During the running-in process, smooth surfaces become rough due to wear.
If the vehicle has a mileage of up to 300 km with new tires, you should be especially careful when driving on wet surfaces.
