The Super Swamper TSL LTB is basically a more aggressive version of the Super Swamper TSL. They utilize the same TSL (three stage lug) design as the famous Super Swamper TSLs but the large lug is offset more to the outside which gives the tire superb traction. 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. The LTB is bias ply constructed, which allows for the more aggressive lugs and very strong sidewalls to better resist the rigors of hard core off-roading. The bias construction also reduces the chances of sidewall splitting when run off road at low air pressure. Super Swamper TSL LTBs are D.O.T. approved off-road, purpose built tires that also provide surprisingly smooth on-road ride. Super Swamper TSL LTBs are available in select wheel size and width variations from a 31x11.50-15 to a 47x17-17 with updated sizes added regularly. Note that the Super Swamper TSL LTBs unique design requires strict attention to air pressure when run on the highway, and actual tread patterns may (slightly) vary based on tire size.
