There is not a tire size restriction there, yet, vehicles should be limited to smaller rigs, it is not real fullsize friendly. Cherokees are as big as you should go. I know someone is going to post up that they have run their F450 up there and had no problems... but we also know that there is the POTENTIAL for problems on tight trails with fullsize rigs!
