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. 
 
Super Swamper TSLs are a bias ply tire that offers unsurpassed traction under the toughest of conditions. The Super Swamper TSLs offer an extremely aggressive design that gives today's on-and-off-road driver a tire that is both directionally and laterally stable and unmatched in performance.  Super Swamper TSLs' are D.O.T.-approved off-road, purpose-built tires that also provide a smooth on-road ride, and yield moderate road noise.    Super Swamper TSLs are available in multiple different wheel sizes and width variations.  Note that the Super Swamper TSLs' unique design requires strict attention to air pressure when run on the highway, and actual tread patterns may (slightly) vary based on tire size.
