A patch kit and method for repairing a tear in a sidewall of an off-road vehicle tire includes an inside patch component, an outside patch component, and a compressing component for assembling, joining and compressing the inner and outer patch components together with the tire sidewall sandwiched therebetween. The compressing component is a threaded rod and a nut or bolt head to dispose on both ends. The inside and outside patch components are rigid or semi-rigid cupped shells with a hole for the threaded rod, so that the rod may pass through the patches and the tear for compression by tightening a nut. To facilitate tire repair without removing the tire from its rim, a recovery cable is temporarily connected to pull together repair components after they are separately pushed through the tear into the tire.
