has any1 noticed a difference or drop in MPG going to a 33" tire, from a 31" tire, with 4.88 gears?!!? It's time for a new set of tires, and what I'm running on a new 4Runner I bought, are 33x12.5 15's. I know I'm losing MPG with the 12.5" wide tires, and moving back to a 10.5" tire. Just wanna gauge running a the stock 31x10.5, 15or or if no loss in MPG, running a 33x10.5 15. I don't know much bout tire sizes and all that, so I'm asking here.

I bought a new 94 4Runner with the 33x12.5 15's on it already.......
