RunOnFlat tires: How it works

How it works

Goodyear's new RunOnFlat technology is based on the concept of reinforced sidewalls inside the tire. When a standard tire deflates, it simply collapses under the weight of the car, allowing the beads to come off the rim and the sidewalls to be squashed onto the road. The pressure totally destroys the tire within a few kilometers. The reinforced sidewalls in Goodyear's RunOnFlat tires keep the tire on the rim and succeed in carrying the weight of the car for up to 80 km after a puncture with complete air pressure loss.

Tire Pressure Monitoring System

Since your tires will simply keep going after they've suffered pressure loss, RunOnFlat technology requires the presence of an on-board TPMS (Tire Pressure Monitoring System) that lets you know that your tire requires servicing. Without such a system, you would have no way of knowing that your tire had suffered a puncture or a blow out.
