the truck has 31's on it now.
I gotta get the fuel filter changed, and i'm gonna sea foam it and see if that helps any!

thanks alot guys!


31's are larger than your stock tires, so you'll want to compensate for that.

My 88 (35's, 5.29's) gets a solid 15-17. My old 94 got 14-18 w/ 33's and 4.88's. My 93 xcab with 4.56's and 33's got 18-21.
