| 摘要 |
The present invention comprises a tire with a support system comprising two adjacent crescent-shaped inserts interior to the sidewall. When the tire loses inflation pressure, perhaps due to sudden puncture, the inserts provide sufficient support for the tire to allow continued normal, comfortable operation of the vehicle until the tire can be repaired or replaced. The first crescent-shaped insert (24), which is nearer the exterior sidewall, has a lower modulus of elasticity (is less stiff) than the second crescent shaped insert (22). The first insert (24) is made of an elastomer (i.e., rubber) cured with a sulfur system, whereas the second insert (22) is made of an elastomer cured with a peroxide catalyst and metal salt of a carboxylic acid, e.g., zinc dimethacrylate. |
