Tires and Wheels

The service life of tires depends on driving habits as well as the right tire pressure and correct chassis setting.

Rapid acceleration, extreme cornering speeds and hard braking increase tire wear. Moreover, tread wear is increased at high outside temperatures and on rough road surfaces.

  1. Please see chapter "Before driving on circuits" on page 17.


Complying with load and speed requirements

  • Drive at an appropriate speed.
  • Do not overload the vehicle and pay attention to the roof load.
  1. Please see chapter "Weights" on page 363.


Checking tire pressure

Low Tire Pressure
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires and causes damage.

  • Always use an accurate tire pressure gauge when checking inflation pressures.
  • Do not exceed the maximum tire pressure listed on the tire sidewall. (Also refer to “Technical data” and Fig. 231 on page 277).
  • Cold tire inflation pressure means: all tires must be cold, ambient temperature maximum 68 °F (20 °C), when adjusting the inflation pressure. Avoid sunlight striking the tires before measuring cold pressures, since the pressures would rise from temperature influence.
  • Check the tire pressure at least every 2 weeks when the tires are cold.
  • Valve caps protect the valve from dust and dirt, and thus from leakage. Always screw caps tightly down. Replace missing caps immediately.
  • Use only plastic valve caps.
  • For safety reasons, don't use tire inflating bottles.


Low tire pressure can cause the tires to overheat and become damaged , even invisibly.

  • Hidden tire damage is not eliminated by subsequently correcting the tire pressure.
  • Never let air out of hot tires. Tire pressure is increased in hot tires. The tire pressure would drop below the prescribed value.

  1. Please see chapter "Tire pressure" on page 366

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires).

As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure warning light when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure warning light illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure warning light.

For further information on the Tire Pressure Monitoring System:

  1. Please see chapter "Tire Pressure menu - Tire Pressure Monitoring System (TPMS)" on page 171.

When tires are warm, the tire pressure is increased.

  • Never let air out of hot tires. This could cause the tire pressure to fall below the prescribed value.
