Interchanging the wheels

WARNING
Rotate front and rear wheels only if the tires are of the same dimension.
If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible.

WARNING
Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel bolts specified for your vehicle's rims.

The wear patterns on the front and rear tires differ, depending on the operating conditions.

Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically wear more on the shoulders and the rear tires in the center.

If your vehicle's tire configuration allows, you can rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If this is not available, the tires should then be replaced every 3000 to 6000 miles (5000 to 10,000 km), or earlier if the tire wear requires this. Do not change the direction of wheel rotation.

Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is interchanged. Check the tire pressures.

Information on changing a wheel and mounting the spare wheel.

pressure On vehicles equipped with a tire pressure monitor, electronic components are located in the wheel.
Tire-mounting tools should not be used near the valve. This could damage the electronic components.
Always have the tires changed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
