im looking at the toyo open country mt but i dont know what size? the Lt315/60/r20 is 35'' tall and 12.6'' wide and weights 65lbs and has a load capacity of 3640lbs. The 33x12.50r20 is same width but a load capacity of only 2600lbs and weights 72.0lbs. the 35x12.50r20 is same width and height but weights 81lbs (16lbs more than 315/60) and only rated at 3195lbs load capacity. the 315 are $14 more than the 35'' and $24 more than the 33. would the weight difference save money in the long run(gas milage)? I thought i wanted the 33 but for the $24 and 7lbs lighter i would love the 35's. what to do? anyone running 315/60/r20 mt's got pics?

thanks for the help guys.
