Run-Flat Tire, Retrofitting/Conditions For Use Of Run-Flat Tires

NOTE:

Using run-flat tires on vehicles is permitted only if the run-flat tire is supplied with the vehicle either as standard equipment or as an option.

Because pressure loss in a run-flat tire is not always visible, these tires should only be used on vehicles equipped with a tire pressure monitoring system. This system warns the driver when the tire pressure falls below a certain value.

The Following Are Permitted:

Direct Measuring System

Indirect Measuring System

Only mount run-flat tires on disc wheels with an extended double hump (extended hump - EH2).

Do not install both run-flat tires and standard tires, even if the two tires on each axle will be the same.

A standard tire can only be installed in exception cases for a short time or a limited driving distance. The specific characteristics designed for driving with a flat tire will not be available. The driver must be informed of this.

Always pay attention to the recommended tire brand. Refer to WHEEL AND TIRE GUIDE, VEHICLE SPECIFIC SECTION  / WHEEL AND TIRE GUIDE, GUIDANCE ON THE APPLICATION .
