so i'm driving down to arizona middle of december. i've got these 33" tires which i got for free, and then i've got my nice 35" mt/rs. would it make more sense to drive on the 33's w/ the 35's in the rig (i'll be wheelin a bit down there) to save the tread on teh 35's, or would it be better to save a small amount on fuel and run the 35's? i've got 4.10 gears and the sm465...
