Summer tires

In October, especially at night, it can easily get cold. When temperatures drop below 7 degrees Celsius, it is time to put on the winter tires. Summer tires are optimum in the temperature range of 10 to 40 degrees Celsius. Below 7, they harden and lose their grip on the road. It is also important that summer tires are stored properly after the change so that they do not suffer from "winter break."

Check tires and rims for damage. If bumps or deeper cracks appear on the tire sidewall, this indicates damage. The tire in question should then be replaced immediately. If the tires no longer have enough profile or are too old, new tires must be added. Minimum tread depth is of 1.6 millimeters, and summer treads are recommended to have a depth of 3 millimeters. At the latest, after 10 years, a tire should be replaced. 

As a precaution, increase the air pressure by 0.5 before storing as the tires lose their air in the winter. If they are reassembled in the spring, then you have enough pressure to get to the next gas station to check the tire pressure. 

Tires on rims should be stacked on top of each other or suspended individually on special wall hooks. Tires without rims must be vertical, in a dry, non-oil or petrol soiled ground. In addition, they should be rotated every few weeks by a quarter of the circumference. 

Tires like it cool, dry and dark. Under no circumstances should you use the tires as a buffer on the rear wall of the garage. If you want to spare yourself the trouble, tires can be stored by companies over the winter for a fee. 

Before dismounting it is recommended to mark the tires with chalk, e.g. with "FR" for "front right" and "RL" for "rear left." This procedure allows for easier installation after the winter.
