Super Swamper LTB Tires 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. Super Swamper LTB 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. Super Swamper LTB Tires have a bias construction which reduces the chances of sidewall splitting when run off road at low air pressure. There are seven sizes available….sizes which are not available in the regular TSL line.
