Abstract: Segmented tires employ segments featuring cooperating recesses and protrusions at opposing sides thereof for mating of the segments with one another in the assembled tire body. Cleated tires with embedded cleats of greater rigidity than the tire body material provide improved traction in muddy or other slippery conditions while the compressible tire body smooths out the ride harshness of the tire. Mounting elements are also embedded within the segments of the tire body for secure mounting and reliable retention of the segments.
