RUN FLAT TIRES

Run flat tires can be identified by the wording 'RunOnFlat' on the sidewall. The tire construction utilises a specially reinforced sidewall, which allows the vehicle to be driven at restricted speeds, up to a maximum of 50 mph (80 km/h) , even when the tire is depressurized.

Run flat tires can only be fitted to special rims, constructed for run flat tire use. A Tire Pressure Monitoring System (TPMS) is mandatory when the vehicle is fitted with run flat tires. See TIRE PRESSURE MONITORING SYSTEM.

If the tire has deflated, the vehicle should be driven with caution, as handling characteristics will be different compared to a fully inflated tire. The distance that can be completed on a fully deflated tire, is typically 50 miles (80 kilometers), but this is dependant on driving conditions, vehicle load and ambient temperature.

Stop immediately if the tire construction begins to break down, or if the tire dislodges from the wheel rim. Typically, this will be accompanied by excessive vibration. A tire driven in a deflated condition must be replaced as soon as possible.

Vehicles fitted with run flat tires are not fitted with a spare wheel, or jacking equipment. Therefore, run flat tires should be replaced with the same type of tire.
