Summer tires

Do not drive with a tire tread of less than 0.12 in/3 mm, otherwise there is an increased risk of hydroplaning.

Winter tires

Do not drive with a tire tread of less than 0.16 in/4 mm, as such tires are less suitable for winter operation.

Minimum tread depth

Minimum tread depth


Wear indicators are distributed around the tire circumference. They have the legally required minimum height of 0.063 in/1.6 mm.

The positions of the wear indicators are marked on the tire sidewall with TWI, Tread Wear Indicator.

Tire damage

General information

Inspect your tires regularly for damage, foreign objects lodged in the tread, and tread wear.

Driving over rough or damaged road surfaces, as well as debris, curbs and other obstacles can cause serious damage to wheels, tires and suspension parts. This is more likely to occur with low-profile tires, which provide less cushioning between the wheel and the road. Be careful to avoid road hazards and reduce your speed, especially if your vehicle is equipped with low-profile tires.

Indications of tire damage or other vehicle malfunctions:

  • Unusual vibrations.
  • Unusual tire or running noises.
  • Unusual handling such as a strong tendency to pull to the left or right.

Damage can be caused by the following situations, for instance:

  • Driving over curbs.
  • Road damage.
  • Tire inflation pressure too low.
  • Vehicle overloading.
  • Incorrect tire storage.

Safety information

 Warning

Damaged tires can lose tire inflation pressure, which can lead to loss of vehicle control. There is a risk of accident. If tire damage is suspected while driving, immediately reduce speed and stop. Have wheels and tires checked. For this purpose, drive carefully to the nearest dealer's service center or another qualified service center or repair shop. Have vehicle towed or transported as needed. Do not repair damaged tires, but have them replaced.

 Warning

Tires can become damaged by driving over obstacles, e.g., curbs or road damage, at high speed. Larger wheels have a smaller tire crosssection.

The smaller the tire cross-section, the higher the risk of tire damage. There is a danger of accidents and property damage. If possible, avoid driving over objects or road conditions that may damage tires, or drive over them slowly and carefully.
