Ok, so I have the ProComp 33-12.50-17 Mud Terrains for my winter rims but they get crap for mileage on the highway, as well as leaving their precious rubber there. I have a second set of steelies for the road and just can't make a choice. Does anybody have mileage v. wear and cost opinions? My first choice is something akin to 32x10.50x17 all terrains. But a 60k rock hard compound is very appealing too. Oh my, all the choices.
