re: 33 inch tires

I did a little googling recently and all I came up with was that oversize tires are of ZERO benefit other than looks. No performance or mileage gains and Negative when it comes to initial outlay and replacement cost.

The bigger they are, the worse your gas mileage gets. They're obviously bigger than stock and they're heavier. If they look good and you like it, roll with them! As far as better gas mileage, I honestly don't know much because I tend to not care but as far as mythbusters go, throw the tailgate down and you get a little better gas mileage.

those 5.7's suck gas period. I own a 1992 Silverado with the 5.7 and I can watch the gas gauge go down. Or up if I accelerate real hard then WAAAYYYYY down Real FAST
