Rockthorn 1.9" tires feature deep, self-cleaning tread blocks that are great for driving on a variety of off-road surfaces ranging from hard-packed dirt, gravel, wet or dry rocks, loose dirt, mud and more. The wide tread blocks are also useful on hard surfaces like slick rock and pavement. The treads wrap around the sidewall to add grip in tight areas and when going sideways across inclines. The all-purpose rubber is hard enough to last while driving on short paved sections, yet still soft enough to get the truck over extra-difficult obstacles like slippery rocks and mossy tree roots.
