The Grabber's tread was designed using strake and chamfer technology. The diagonal tread voids are the strake-their design was engineered by looking at the way animals run. For instance, when a cheetah runs its paws spread open to give it a wider footprint. The strake built into the Grabber allows it to have a wider footprint for better traction when spinning at higher speeds. The tread blocks are chamfered to allow the tire to bite harder into rocks, dirt and mud while also allowing it to be self cleaning so it doesn't cake up with mud.
