The invention relates to a tire patch for off-road tires. The addition of an effective amount of bisimide to at least the base breaker gum and the upper breaker gum reduces the need to reduce the sulfidation of the gum base during repair and use. In this application, bisimide is more effective than other reversion inhibitors.
