Run Flat Tyres
When a standard tyre experiences a drastic loss of inflation pressure, the rim of the wheel brings the full weight of the vehicle to bear on the collapsed sidewalls. You can barely manoeuvre the vehicle and the tyre is destroyed.
Run flat tyres have sturdy, reinforced sidewalls that support the rim should the tyre suffer a loss of inflation pressure.
What To Do If A Run Flat Tyre Has A Puncture
Due to the run-flat properties of these tyres, you may not notice any tyre defect however: your vehicle may be equipped with a Tyre Pressure Monitoring System that alerts you to any drop in tyre pressure.
In the event of a tyre defect:
- immediately slow down to a maximum speed of 80 km/h (50 mph)
- avoid sudden or erratic braking and steering manoeuvres and be especially careful negotiating bends
- do not drive more than 80 kilometres (50 miles) after the defect is detected
- have the defective tyre replaced as soon as possible.
