What is the Super Swamper LTB? The Super Swamper LTBs are in the same basic Three Stage Lug design as the famous Super Swamper TSL’s but a little more aggressive. The large lug is offset more to the outside which gives the tire superb traction. It is in bias ply construction which allows for the more aggressive lugs and very strong sidewalls to better resist the rigors of hard off-roading. The bias construction reduces the chances of sidewall splitting when run off road at low air pressure. There are many sizes available that are not available in the regular TSL line.
