One more thing, the tires will almost always cost more for the larger wheels.

Don't mean to hijack, but no love for my question?

Here's what we know about your question...

1) Your truck had 18" wheels/tires.
2) The dealer swapped them for 20"
3) The payload sticker on your truck was for 18" wheels/tires.

You want to know if your payload capacity is decreased.

I feel like this is one of those questions where not enough information has been supplied to provide an answer.

FWIW.........

I was originally going with 285/75R17's. I like the look of the extra rubber on the sides and how they feel off road.

But, I finally went with 275/65R20's, and I'm ashamed to admit it, FOR THE LOOKS.

I kinda like the 20" look on a 2016 truck. Sign of the times, I guess.

They were both about the same height, but the 17's are ~ $30 cheaper (each).

Happy hunting.......

i am looking at that size too, 275/65-20 for my crew 4wd xtl. is there anything i need to be aware of? is there lots of clearance without a lift kit? does my computer need to be adjusted for tire size? i know my speedo will be off if i don't change the tire size in the computer, but are there other things to worry about like transmission issues, severely effecting tow capacity, etc... anything?

thanks in advance

I have a Rough Country 2.5" level kit on the front with zero clearance issues. The tires just miss the Weathertech flaps on the front at full turn. But they do miss.

The wheel off-set will/may make a difference. I have the stock size Ford Racing wheels.

I purchased a Hypertech speedo calibrator.

Truck functions better than stock including transmission, handling and all. Towing capacity shouldn't change.

Any good 4x4 off road shop can give you good advise on tire clearance.

IMHO...F150s should be on 20s at least...both 2 and 4 WD...It just looks so good..the 18s and 17s just don't look right with toy tires and wheels..

I guess that's why there's options - because some people also feel that a truck should come with 17's / 18's and not 20's or 22's, etc.

That's the "myth" part of this thread.

Actually, I said the wheel weighs LESS than the tire.

Since the OP asked if the ride height would be the same, how can you jump to the conclusion that he was insinuating the same height tire on 18" or 20" wheels ? How would the ride height change if the tire diameter was equal ? That question meant to me the OP was not knowledgeable regarding tire / wheel combinations. I was pointing out that the same width to aspect ratio tire in two different wheel sizes would get you two different height tires. Many people believe that the only difference between a 275/55/18 and a 275/55/20 is the diameter of the wheel opening. I was pointing out that isn't so.

In a modern, cast or forged aluminum wheel the difference in weight between an 18" or 20" model is usually 2 - 5 lbs. - about the same amount as the difference in weight between an 18" or 20" tire of the same tread style, width, sidewall strength and overall diameter.

If you read my entire response to the OP, you will see that I was trying to point out that HOW you use your truck is more important than the small weight differences you will encounter if you change from 18" to 20" wheels and keep the same overall tire diameter.

As far as your opinion on the relevance of my post, I posted information that is correct. That makes the post as relevant as anything you have offered, especially as an answer to the OP questions.
