how much would a full size spare cost? I saw an ml the other day at the trailhead( Iwent on the trail, they just were towing dirt bikes) but he had BF goodrich all terrains 265 75 R17 and they looked great and really rugged... I wish i could trade with him.
you should come out to CO and do some of our back country (not implying differene in difficulty, just saying it'd be cool to offroad w/ another ML since i have never seen another one on the trails.
