Bridgestone run-flat tires give drivers the peace of mind: drivers know that they won’t be stranded from a flat tire.
With Run-Flat Tires, you can drive at least 50 miles Flat tires account for about 10% of breakdowns
The Bridgestone Support Ring inside the run-flat™ tire supports the vehicle after a loss of air pressure allowing the tire to function and the vehicle to continue on the road.
By having a protrusion (Cooling Fin) on the side of the run-flat™ tire, the movement of air around the tire’s sidewall is accelerated as the tire spins. This provides a cooling effect to the tire’s surface area.
To prevent a run-flat™ tire from separating from the wheel when tire pressure is lost, specifically designed beads are used.
