I cannot comment on their; ride, ultimate grip, handling, turn-in response, etc.
But, I will comment on their toughness/durability, since there was a FoST owner (a former U.S. nationally ranked rally pilot himself) at last July's NEFR who had these mounted on the factory FoST wheels in a factory FoST size (
40 series sidewalls!! ), and took them out onto the stage roads, with very sharp rocks, embedded boulders in the forest road surfaces, and really bad ruts and washouts, with
NO resultant; flats, sidewall bubbles, or any other problems.
He did
NOT 'take it easy' when traversing these logging roads either!
I thought that he was crazy for even
attempting this, but he knew better.
