Volkswagen Polo Service & Repair Manual: Run-Flat Tire, Retrofitting/Conditions for use of Run-Flat Tires

  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.
