Abstract
Abstract A grouser retainer that is positioned between a belt and a tire carcass provides an anchor for attaching one outboard end of a grouser to a tracked tire assembly. A pair of grouser retainers, one at each edge of the track or belt, are used to anchor each grouser as each grouser retainer is less than the full width of the tire tread.
