There are several ways to Determining the right tires for your car. Next to the counselor we will provide you with a practical how-to-correct-tire-Video ready, in which you will find out everything you need to know about tire size.
Video: which tire is the right one?
Which tire size can I drive and where is it?
You can use the code on the side edge of a tire to find out which information stands for which value.
Example: tire designation 255/35 R 20 97W
- 255 stands for the tire width in millimeters
- 35 for the flank height in percent, here: 35% of 255 mm
- R designates the construction – here radial
- 20 is the diameter of the rim in inches
- 97 stands for the load index
- W for the speed index
The speed index denotes the maximum speedthat you can drive with the respective tire: L, M, N, P, Q, R, S, T, U, H, V, VR, W, Y or ZR. For example, the letter P stands for 150 km / h, V for 240 km / h, you can quickly find out the entire list online. By the way: if the speed index on the tires is lower than the maximum speed entered in the vehicle registration document, these tires are not permitted for that vehicle.
When are tires too old?
Basically, tires should Driven for a maximum of 10 years, better 6 to 7 years. If you would like to see the age of the tires (e.g. during a vehicle inspection), you will find a bordered area on the tire wall at the end of the sequence that begins with DOT. For example, 3116 would then be in the box for the 31st week of 2016 – that is when the tire was produced. If the information is older than six years, you should negotiate a new set of tires right away, especially if the tread depth no longer fits. That is 3 mm for summer tires and 4 mm for winter tires.
EU tire label
The EU tire label offers additional assistance when buying tires, similar to the energy efficiency label for electrical appliances such as refrigerators. On the label for tires, the rolling resistance is indicated first, i.e. the fuel efficiency from A to G, the wet grip efficiency from A to G and the rolling noise in decibels. If you drive a quiet car, this could be important to you.
