RunOnFlat
Keeping You Going
Goodyear Dunlop RunOnFlat tyre technology allows your vehicle to keep going after a puncture or loss of pressure. Even a completely deflated tyre can be driven for up to 50 miles at up to 50mph, making sure you can get to a safe place where the tyre can be examined.
It is important to remember that your Tyre Pressure Monitoring System (TPMS) sensor requires servicing at every tyre change interval. If a flat tyre warning appears make sure to contact you're local HiQ Centre for help.
What is Goodyear RunOnFlat technology about?
The ingenuity behind RunOnFlat technology is all to do with the tyre's reinforced sidewalls. Highly resilient rubber inserts support the weight of the car even when the air pressure, which is what normally does this job, is gone.
What happens when a tyre deflates?
When a conventional tyre gets a puncture, the sidewalls collapse and continuous driving forces the tyre to detach from the wheel rim, causing it to quickly overheat. The result is a lack of control in steering and braking.

How it works
Goodyear RunOnFlat tyres, however, have special inserts to support the sidewalls if the tyre loses air. These bend as required to distribute the forces of compression and tension caused by the car's weight, even if the tyre has totally deflated.

Two primary modes of bending create a road-to-load transfer from the road to the rim.
