ok, i know that getting bigger wheels will decrease the mpg. but what if we get smaller wheels (13's or 14's), will that increase the mpg? just wondering...

no answer, but also wondering. how did people determine mpg on larger wheels, when the speedo is off?
what if you already gain your speed and cruising, would it be larger wheels gets more mpg?
i don't know, i'm always wrong most of the time

I don't think so, and your speedo would be wrong. Most bigger wheels get a lower sidewall, which is really about the same as stock. Unless you go 20"+.

Get some 13" Reverse knock-off Wires and let us know. And Some wheel well flares so they don't look wierd.

My 18's and tires are smaller than my stockers.

We need a sizing chart here. Something that will show relative mph in relation to wheel diameter....... I know I've seen something like it, but can't remember right now..........

Anyone? Brad, do you copy??

I guess it's a calculator of sorts. Haven't tried it personally, not endosing it either. Just trying to share.
