Volkswagen Touran Service Manual: Run-Flat Tire, General Information
| Run-flat tires have a reinforced sidewall in comparison to
standard tires. This reduces the tendency for the sidewall to
roll when there is a loss of pressure and prevents the sides of
the tire from being pinched. This allows the vehicle to be
driven while still maintaining close to normal driving behavior.
It also eliminates the need to install the spare tire in
dangerous situations such as on the highway or in poor weather
conditions. |
| When there is a flat tire, the vehicle can still be driven
to the nearest workshop (within approximately 50 km) as long as
the vehicle speed (maximum 80 km/h (49.7 mph)) and driving style
are adapted accordingly, see the Owner's Manual. |
| If there is a flat tire, the driver is ultimately
responsible for checking the affected tire and deciding if it is
possible to continue driving. |

| -II- Tires without Air Pressure |
| If the standard tire -2- loses
pressure, the rim pushes the side wall together. When the tire
is the flat, the sidewall becomes extremely hot from the rolling
motion and or is pinched. This destroys the tire. |
| In run-flat tires -1-, the
reinforced sidewall (-red-)
supports the tire. Because of a special rubber compound and the
reduced flexing of the reinforced sidewall, the tires does not
become as hot and the vehicle can still be steered. |
 Note
| Read and follow the special requirements for using run-flat
tires. Refer to
