Has anyone switched to a smaller tire?
I have a 2014 Ram 2500 6.4 Hemi 3.73 pulling a 30' fifth wheel which weighs approx. 9000lbs. loaded. Stock tire size is 275/70r18. Truck has close to 17k miles and the original Firestone tires need to...

I have, but on a wimpy 180 hp Nissan Xterra.
Stock size was 265/70R16. (About 30.5 inches)
I came into a free set of 33 inch tires that I ran for a few months for some off roading. Big loss of power both due to the effect on gearing, and the higher weight.
I then came into a free set of 255/65R16 tires on Pathfinder rims. Definitely felt a difference, even relative to the stock size tires.
