The Super Swamper TSL is the culmination of nine years of development and testing which produced the ultimate tire tread design by pairing the concept of the Original Swampers distinctive chevron tread pattern with the famous, trademarked and patented Interco TSL (three-stage lug) tread design. TSL is a lug pattern with massive short, intermediate and long lugs that are each uniquely arranged, proportioned and spaced which allow them to bite quickly and self-clean rapidly; this distinctive tread pattern, along with tougher side walls, a quieter ride and increased mileage offering from that of the Original Swamper.
