Volkswagen Touran Service 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

→ Chapter "Identification". |
| Pay close attention to the installation instructions. Refer

→ 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

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. |
