How much would changing from a 31" tire to a 33" affect engine rpm and fuel economy? I want to get a big bigger tires and not lose much fuel economy and engine lugging on hills.

Yea you shouldn't notice much of a difference. I didn't notice any power loss going from factory 33's to my 35's that's why I'm contemplating going to 37's now lol.. I did loose like 2 mpg's tho.
