Tire size?

Has anyone switched from 37" to 35"tires? I am curious how much difference I would notice in performance and mpg's if I down sized.

I switched from 33's to 35's with a 2.5" lift. I noticed about 1.5 mpg difference. Not much, but I imagine you will see some. Therefore your talking 50-55 more miles out of a stock tank...

I lost almost 1 mpg going from 33.2" stock tires to 33.2" by 12.6" wide trail grapplers. Tires are heavy!

Yea I'm running 37" trail grapples right now. Thinking about switching to 35's to take strain off the tranny and do a little better on mpg's

Yep. Like Travis said these tires are heavy. I also went from a HD300 tune down to the 250.
