Operating principle

The run-flat divice is made of special engineering plastic injection molding and installed on the rim of the tubeless tire, which does not affect the normal operation of the wheel, nor does it affect the performance and safety of the car. Once the tire is flat or blown, the cylindrical surface of the explosion-proof tire support device contacts the inner wall of the tire crown to support the wheel load. Under the action of the wheel rolling thrust, the The run-flat divice and the rim rotate each other to form a differential speed, so as to make up for the change of the circumference difference of the tire side, timely release the movement resistance of the sudden increase of the tire, effectively avoid the vehicle due to the loss of control of the tire resulting in sideslip, turn, rollover and other car accidents, so that the car can still be controlled and safely driven for a distance.
