He mentioned in a previous post going with 315’s, that’s what I was referring to. If you stay stock size the difference isn’t huge, go up in size and it’s a different story.
Yep, tis true and as you say have done it before but do like the look of it. Coming from a 6.0, GMC 2500 gasser, Z-71 giving me a solid, dependable 10-11mpg, I can tell you a 40% increase in mpg is a nice thing. And, with a 38 gallon tank.
