20s or 18s
Deciding I’ll be ordering my truck within the next few weeks.
I know this topic has been discussed to death but I figured I’d get some new opinions. I know they are the same height overall and the 20’s will have less rubber than the 18s
20” cast or the 18” ??
Truck will be a CCSB
thanks

The 20" look cooler and will handle better with less sidewall flex. The 20" will be a little lighter and might get a little bit better fuel mileage with slightly less rolling resistance.
I guess it depends on how you plain to use your truck the choice is yours.

As said above, what is making you question wheel size? Ride, capacity or cost? If you're concerned about ride and you order the snow plow package or max suspension package, it won't matter which wheels you choose. The rough suspension will mask any difference in ride quality from the 18s. I don't have the snow plow package and I have 20s. Mine rides great.

I'm not a fan of the big wheel, reduced sidewall trend. I prefer to stick to the old 4X4 recommendation of having your wheel be no more that half the size of your tire (i.e. 18" wheel = 36" tire) but, I hate change and and the truck industry has chosen to move on without me. I'd say compare the price of replacement tires for the two. For reasons I can't understand, the bigger the hole in the middle of the tire the more they cost. You're actually getting less tire. How does that cost more? Aside from price, odds are you won't notice much of a difference. These trucks have stiff suspensions. The little bit of extra sidewall, especially if you are running load range E tires, probably won't be real noticeable and odds are you aren't going to be doing much in a brand new super duty that is going to require airing down. Pick the ones that you think look best and roll with that.

Just a side note I air down my 18" almost every time I go on vacation as I pull my trailer to the dunes. I have to air the truck and trailer down to 20 PSI or I'm stuck. As far as ride goes I set my tires to 60PSI when I'm not towing and a friend of mine has 20" wheels on his Super duty and I can tell a difference in ride between the two and he can too.
The OP did not say what he was going to be doing with his truck and we all use our truck a little differently. ..
