The Super Swamper TSL (TSL = Three Stage Lug) is built on the principles
of the original Swamper 78 series which, literally and figuratively "broke
new ground" when it was first introduced back in 1970 by Interco Tire
Corporation. The Super Swamper TSL is the classic bias ply mud tire
that offers excellent traction in mud and on the rocks with extreme
durability.
