Hey y'all, finally I have my lil rig back on the road after replacing the head, and I really want to increase the tire size to something with a little more meat on them compared to the pathetic 225/75/15's on them right now. One of my concerns, especially with increasing fuel prices, i'd how much do y'all think goin to different tire size will be? I know there is a fantastic wheel and tire size chart, but I wanted your opinions on what is the best size to go with and sticking with 15x7 wheels? Pics would be great too.

Oh yeh btw I hope everyone had a great holiday and wish y'all anapy new year too. Thx.
