Tire cleaning
Do not clean tires with compressed steam. A jet of hot steam close to the tire will make the tire unrepairable in a few seconds, even if cold water is immediately applied. For safety reasons, it is recommended to replace a tire cleaned in this way.
After a tire has been in contact with oil or grease for a long time, it must be replaced. The tire will first bulge in the appropriate place and then return to its original shape, appearing undamaged at first glance. However, the tire's load-bearing capacity is greatly reduced due to the effects of fats.
Tire storage
Tyres should be stored freely in a cool, dark, dry and, if possible, draft-free place and should not come into contact with lubricants.
Tires should be stored in a garage or basement lying down or suspended if they are mounted on rims.
Before removing the wheel, increase the tire pressure slightly (0.3-0.5 bar).
For winter tires, use your own wheel rims, as remounting tires does not save costs.
Tire running-in
New tires have a particularly smooth surface after manufacturing. Therefore, tires need to be run in - this also applies to the spare wheel. The initial wear during running in makes the tire rougher.
During the first 300 km you should drive very carefully, especially on wet surfaces.
