Abstract
An insert for tubeless tires to maintain vehicle control and prevent tire collapse in the event of puncture or other loss of air pressure. The insert has a toroidal center core of solid material, a foam casing of compressible but resilient foam material annularly surrounding the cylindrical core, and a thin outer flexible shell annularly surrounding the casing.
Claims10
The combination of an inflatable tubeless tire and an insert within the tubeless tire for preventing collapse in the event of loss of air pressure, the insert comprising:
- (a) a toroidal core of solid material;
- (b) a resilient foam casing annularly surrounding the core;
- (c) a thin outer flexible shell annularly surrounding the casing;
- and
- (d) flange means flexibly and integrally formed as part of the core for bowing out towrds the tire sidewalls after puncture of other loss of air pressure to give added strength to the tire sidewalls and prevent additional collapse.
The combination of an inflatable tubeless tire and an insert within the tubeless tire for preventing collapse in the event of loss of air pressure, the insert comprising:
- (a) a toroidal core of solid material;
- (b) a resilient foam casing annularly surrounding the core;
- (c) a thin outer flexible shell annularly surrounding the casing;
- and further including wedge means attached to the interior of the tire sidewalls to give added strength thereto and prevent additional sidewall collapse after puncture or other loss of air pressure.
The combination of an inflatable tubeless tire and an insert within the tubeless tire for preventing collapse in the event of loss of air pressure, the insert comprising:
- (a) a toroidal core of solid material;
- (b) a resilient foam casing annularly surrounding the core;
- (c) a thin outer flexible shell annularly surrounding the casing;
- and
- (d) means for detachably securing the insert to the inner bottom tire wall to prevent slippage of the insert relative to the tire.
