Taking a guess I would probably say cause of the tread pattern, or lack of ha. Seems like it was specifically designed just for the radial tire class. They look pretty radical.Just out of curiosity why cant these be run on the highway? These tires are way more stable than the 26x10.5 et streets i ran before
it says that stuff on alotta partsThese are race tires. Do not run these on the highway.
