The Berserker tread pattern is a throwback to the classic four lug design of the 70s and 80s with new features that bring the performance into the modern era. - Staggered tread pattern. - Step downs. - Fine detail. - Generous siping. - Lightning bolt sipes on the center lugs for unbeatable traction in any terrain and in the deepest of muddy ruts. - Outer shoulder lugs are staggered for extra bite when the going gets rough. - Scale rim guards into the bead seat of the tires just like the 1:1 version.
