I probably lost 10-20% fuel mileage in going from ~stock to 33" tires and my current lift.


Really? I actually GAINED fuel mileage when I changed to 33's on the truck w/ an auto tranny. Maybe the gearing in the tranny + the different axle diffs (4.30's, I think)? Of course, the speedo was thrown off, too <img src="/forums/images/graemlins/lol.gif" alt="" />
