The Super Swamper TSL/SX II is the second generation TSL/SX, and offers increased siping over that of the first-gen version. This allows for better grip and traction sought after for various on and off-road situations. The TSL/SXII also incorporates the Super Swampers distinctive chevron and famous, trademarked and patented Interco TSL (three-stage lug) tread design. The TSL/SX II is also is designed for extremely tough off road conditions where sidewall strength and protection is needed to withstand the severe scuffing from running in ruts and snagging roots and rocks. This TSL/SX II has a strong nylon or polyester bias ply body with dual belts under the tread and wrap-a-round lugs. The sidewall lugs not only protect the sidewall but also provide extra traction when climbing out of ruts. The Super Swamper TSL/SXII offers unsurpassed traction under the toughest of conditions and gives off-road enthusiasts a tire that is both directionally and laterally stable and unmatched in performance. Super Swamper TSL/SXII tires are D.O.T. approved off-road, purpose built tires that also provide a smooth on-road ride. TSL/SXII tires are available in a variety of popular wheel size and width combinations with new sizes being developed regularly. Note that the Super Swamper TSL/SXII has a unique design that requires strict attention to air pressure when run on the highway, and actual tread patterns may (slightly) vary based on tire size.
