Run-Flat Tire, Retrofitting/Conditions for use of Run-Flat Tires

~2min read
Caution 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 systems. Refer to → Suspension, Wheels, Steering; Rep. Gr.44.

Indirect measuring systems. Refer to → Suspension, Wheels, Steering; Rep. Gr.44. Only mount run-flat tires on disc wheels with an extended double hump (extended hump - EH2). Refer to → Chapter "Identification". Pay close attention to the installation instructions. Refer to → Chapter "Tires, Mounting". 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; Rep. Gr.44.

Run-Flat Tire, Repair

WARNING

Run-flat tires must be replaced after they have gone flat.

Pay close attention to the installation instructions. Refer to → Chapter "Tires, Mounting".

General Information

The wheel must be inspected before mounting, as with conventional wheel and tire systems.
Check the rim for damage after a flat tire (true running, axial run-out, other damage) because the rim could be damaged in an emergency by driving through a pothole. Refer to → Chapter "Wheel, Mounting".
A damaged rim should be replaced.
