Tire/Rim Weight and Mileage thoughts

Hey guys something like this may already be up in a thread but maybe somebody's too lazy to look.. I'm running 17 inch incubus chrome rims and 31" Tires and run about 17 mpg average in my 09 2 door wrangler x. I'll be in the market for new tires and rims this summer and am looking for some info on the weight setup and mpg between what I have and 32 inch duratracs and 15" rims.

Simplified here just wondering

Weight and mpg thoughts comparison:

31" Tires and 17" rims

32" Duratracs and 15" rims

Thanks!

You'll have more rolling resistance with the larger tires, but since the change is only an inch or so, I don't think it's gonna affect your mileage TOO much (although tire WIDTH also plays a big part, so it's hard to say). And the DuraTracs are very light tires...whether the 15" rims you choose will be light is gonna depend.

Here's a recent thread from Rics1997 discussing this issue:

Rick is all over that stuff. All I know is my mileage went from bad to worse when I put on my 35's.

When I switched my rims from the stock rims to a set of spyder locks (these things are super heavy) I lost almost 2 mpg, and thats runing the same tires that came with the jeep.
