Does anyone know the weight differences? I thought I could only tolerate the 18" as I think the 20's look weird. Are there any advantages to the 20s other than the way they look?

Our brakes are pretty big up front so some wheels might barely clear them. I know with my KMC XD Battalion in 18" they barely clear them and since the wheel weights are mounted on the inside of the barrel, they actually rub on my caliper and make a noise. I had to grind the weights down after the fact.

Considering these trucks come with 17's from the factory on some models those must be some thick weights.

lol - found this out today, but the spare tire is an 18" vs the 20s that came with the truck. If we get a nice warm spell when I am off, I should weigh the two 20 vs 18 with tire on it to see if there is much difference.

I went with aftermarket 18s since the price to get new 20" tires in a stock size wasn't much less then getting new rims and one size larger tire in 18s.

Some wheels have a higher load rating than others. There is not a form for wheels and tires on the 2015 Ram bodybuilder, but you can use the 2014 Ram bodybuilder spec sheet in the link below since almost all 2015 wheels are carryovers from 2014.
