Re: What Tire size to Run with 4.10s

I would run 255/85s. You can tell the difference in less rolling resistance and that will offset the greater diameter that lowers RPMs. With those two factors you can expect a slight boost in MPG. Or at least that has been my experience

'72 K2500 Wideside Sierra Custom Camper: 350/TH350/4.10 Power-Lok...'The 72'
