Super Swamper TSL SX Tires were designed for extremely tough off road conditions where sidewall strength and protection is needed to withstand the sever scuffing from running in ruts and snagging roots and rocks. Super Swamper TSL SX Tires have 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.
