Dumb Question: 17" v 18"--any difference?

I'm just curious--I've got a '13 F250 w/ 17" wheels. Apart from cosmetics, is there any benefit to swapping over to 18" wheels/tires? Load capacity, mileage, tread life, etc.?

I suspect a resounding "nope" but have wondered for awhile...

Can be load rating differences, but for an F250 you wouldn't need the higher rating.

I have kept the 17" wheels on my truck but went up to a bigger tire, 285/70/17 over the original 245/75/17, fills the wheel opening better and gives better ride and handling.

I don't think you'll find any difference Icthus - my '08 F250 came with 18" Factory wheels/tires when I bought it new and the first week I had it, I had it fitted with a set of 17" X 8" Helo wheels and 35X12.5R17 Toyo tires. I went down to 17s because 1.) I like the tall sidewall look and 2.) the more sidewall you have, the better the tire squats when you air it down. I Beach Camp and have to air down to carry my slide-in camper onto the soft beach sand. My new 2015 F350 has Factory 18's and I'm staying stock so either way, it works on the beach. On the road - I saw absolutely no difference. Let's see what others say... I'm definitely no expert.

"LtngDrvr" has another point I forgot about - the more sidewall you have, the softer the ride!

There should be no substantive difference between 17" and 18" wheels on your F-250. Only one inch difference in wheel diameter would likely be very difficult to notice from a handling perspective on a truck like yours. Going to 18" wheels gives you a few different tire size choices, most notably from my research the availability of a 285/75/18 in a few select tires for a 35" tall tire on the stock wheels with stock suspension. So it really comes down to cosmetics and available tire sizes and tread patterns.
