What do you mean by good tires

Mixed tires not recommended

If a tire breaks or wears out, it has to be replaced. It would be cheapest to buy just a single new tire. But can you use different makes or different types of tires?

Tires from different manufacturers, tread types or rubber compounds on a carcan negatively affect the driving stability of the car. This becomes particularly clear with aquaplaning, braking or cornering. Although the legislator forbids the so-called "mixed tires" or impermissible combinations of permissible tire sizes - with "mixed tires" officially only the combination of radial and diagonal tires on one vehicle is meant. Since modern tires are almost exclusively radial, this prohibition is practically meaningless.

Nevertheless, in the opinion of the ADAC, many of the permitted combinations are not recommended. The differences in the mix of summer and winter tires are particularly noticeable.Winter tires behave significantly differently due to the special rubber compound and profile design. Greatly different tread depths should be avoided as well as the combination of run-flat and normal tires.

That's what the legislator says

When it comes to tires, a lot is allowed: the law only states thatMinimum tread depth of 1.6 millimetersin front and the same tire size in front (unless it is expressly permitted in the vehicle registration document). The combination of diagonal and radial tires, also known as mixed tires, is prohibited. However, diagonal tires only play a role in classic cars.

At least the same profile depths per axis

Anyone who has to buy a new tire should therefore try to get the same type of tire. However, since this is not always possible in practice, at least one axis should be uniformly equipped. in theOtherwise, the tires with the better profile belong on the rear axle (for both front and rear-wheel drive vehicles). The operating instructions for your vehicle always provide more information here!

By the way: If a young, little worn tire was damaged, it shouldPossibility of professional repairs being checked. In this way, costs can be reduced in many ways. In addition, the question of the new tire is superfluous.

Particular risk for all-wheel drive vehicles

Here it is essential to follow the specifications in the operating instructions. A very different tread depth at the front / rear could, for example, lead to damage to the center differential, which balances the speeds between the front and rear axles.
