What is tire wear?
Tire wear is the term used to describe the wear and tear on the tire. This can be determined by the decreasing tread depth, as the rubber of the tires rubs off over time when driving on the road. Winter tires in particular, which are used until summer, wear out faster due to the dry surface.
How long do winter tires last?
According to general statements, a wheel should be replaced approximately every 10 years. Leading test centers such as TÜV and DEKRA recommend replacing it earlier, depending on wear and tear, namely after 6 years. A set of tires has a service life of around 40,000 to 50,000 kilometers. However, this also depends on other factors, such as driving style, air pressure and storage.
What tread depth should the tires have?
The only legal requirement for cars is a profile depth of at least 1.6 mm:
“The main profile must have a profile depth of at least 1.6 mm over the entire circumference; The main profile is the wide profile grooves in the middle area of the tread, which takes up about 3/4 of the tread width. “§ 36 StVZO, paragraph (3)
With this minimum tread depth you can also get through the general inspection (TÜV). However, it is not recommended to drive tires with such a low profile. Because even with a profile depth of 4 mm, the Adhesive properties of tires after. Therefore, for safety, it is recommended to use winter tires when reaching with a profile depth of less than 4 mm. In our guide you will find more information about the tire profile and how you can best measure it.
Which factors contribute to tire wear?
Besides the annual mileage and the Quality of tires there are a few factors that you have in your own hands when it comes to tire wear. This includes:
Air pressure: If the air pressure in the tires is too low, they lie wider on the road and wear out more over time than intended by the manufacturer. As a result, the vehicle’s tires then have to be replaced more frequently. Excessive tire pressure is also damaging, because then the tire will wear more heavily in the middle, i.e. unevenly overall. One is also recommended if your car is heavily loaded Adjustment of tire pressure.
Driving style: Do you drive your car in a sporty way, are you fast on the road and take sharp corners? Then you have to expect increased tire wear. Especially if you often drive on bad roads. A more cautious driving style definitely has a positive effect on the life of your tires.
Storage: If you put on summer tires in spring, it is important to store the winter tires optimally. The rubber compound of the tires is vulnerable, so one is recommended dry, cool and dark storage. Because excessive heat and moisture can cause cracks. The tires can also deform. Of course, you can also have your tires stored professionally, for example in a workshop.
