Had 33x12.5r15 Mudstars on my old surf, and have 305/70R16 on my GU. Found them to be better than average in mud, pretty bad in wet weather (i have them at 42-44psi daily though). I drive my GU every day with no problems. Tyre noise is there, but its not as loud as it used to be (either worn in or im getting used to it). The surf did 20xxx with them and they still had approx half the tread when i sold the car. I've had these on my Patrol since i got the truck mid last year and theyre still wearing evenly and still have approx 80-85%. For the $210/tyre that i paid i cant complain. Theyre great cheapies for money concious people who dont want ATs.
