That seems pretty wide? I BELIEVE Shinko makes a 2.75 X 10 that is pretty wide, and will work on that 3.50 rim. As far as I know, that tire was made specifically for Extreme, and the Shinko is what the guys are using. Good luck. --L*64[
Shinko makes a 3.50x10 but the tread does't look very deep. Anybody running anything else?
