Caution
It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.
Installing/Conditions for Using Run-Flat Tires
Caution
It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.
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 systems
- Indirect measuring systems
Only mount run-flat tires on disc wheels with an extended double hump (extended hump - EH2).
Pay close attention to the installation instructions.
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.
