Uncle bought a 3/4 ton chevy that had them when he bought it. So far he's had great luck with them as far as rain/snow/dirt traction (really good, actually), but they are wearing super quick. And i dont know if its because they are super soft or what, but he's had to replace 2 due to unfixable flats. One was actually a T-handle allen wrench he ran over in the street, and it was the rounded 't' part that penetrated the tire.. lol
Good performing tires, but he wont be replacing them with the same thing for sure.
