I had 'em on a 2000 f350.......
Powerstroke, crewcab, winch bumper... heavy truck. I didn't like them at all, sidewalls were too spongy. Was like driving a boat down the road. Replaced them with my usual brand, Michelin LTX's, knew I shoulda done it in the first place.
If you want to try a set, try Discount Tire, if you have one nearby. I have a good relaitionship with them here in Abq, and they credited the Yoko's full price against the Michelins when I complained. They do look like a good tire, maybe woulda worked on a lighter truck.
