Downsize 2019 platinum rims to 18” or 20”

[Tom Brennan]

Hi, I live in New England and want to ditch my 22 inch Platinum rims for a tire with more profile and more of an all season set up. I also off road on a beach and will be airing down. I understand you can break the bead on low profile tires when airing down with low sidewalls. My question is, should I go to 18” rims or 20”? And are there ramifications for the speedometer or other electronics? I have a 2019 Platinum Expedition. Also happy to take tire recommendations. Thanks.

I just pulled my 18” wheels off today and put on a set of snowflake 20” because I couldn’t find a set of 22” platinum wheels that were in my price range. I went the opposite of you, I don’t off-road so I wanted a little stiffer ride.

As far as the tire size you will be pretty much 2” taller on tire height which is about 3.5 mph off on speedo. The width is less than a 1/2” difference. Like I said not much different. As long as you use the 275/65/18 factory size you will be fine. If you have the Forscan software you can change your tire size.

I don’t think that there will be any issues with the suspension and wheels, some of the other members can chime in on that for me. Since you have the platinum you probably have the CCD suspension.

I would say if you are going to air down and want more tire options with off road tread then go with the 18” wheels. You will gain 2” of sidewall.

Any Expedition since 2015 shipped from the factory with 22’s has CCD....just for clarity.

Your speedometer doesn't care what size your wheels are. It cares what height your tires are.....

@kodigray2015 we should have swapped rims! Thanks for the reply.

So all I have to do is make sure the height is the same. Thx.

Yes, maybe we should still swap, I still have mine, they are the factory 2019 XLT rims and what I consider mint condition.

Height size to keep speedo same yes. But the factory 18 tires will fit under there.

I’m putting on a set of Mastercraft Courser HSX tires. Good traction on most anything except deep mud and rock crawling. They do great in snow.

@kodigray2015 I would be happy to swap - not sure what shipping costs would be. Want me to take pics of my rims?

Shoot me some pics, I’ll show them to the boss lady and get her thoughts.

Factory rim and tire sizes here: https://www.wheel-size.com/size/ford/expedition/2019/

To try non-factory sizes, and see the effect on your speedo, look here, click Alternative Sizes, click on More Wheel Sizes and choose the rim diamter you're interested in: https://tiresize.com/tires/Ford/Expedition/2019/Platinum

My Platinum Expedition came with the stock 22” rims. I bought a set of factory 18” rims and painted them flat black to have as a set of dedicated snow tires. The height of the tires is the exact same. (https://tiresize.com/calculator/)
I like my winter tires to have taller sidewalls and narrower tread with which provides protection for driving over uneven pot holes and prevents floatation over snow

I don't think I have seen these on a deal like I received back last fall, but they work just fine as replacements for my 22". I live just outside of Boston and matched them with snowflake tires. I would say the width of these rims (18x8.5") and tires didn't give me incredible snow traction, but I was looking for a balance that I could run when there wasn't snow on the ground. The rims were a steal at $59/ea. The CA co (I think Performance Plus Tire) now has them at a difference price. I still have my 22"s and putting back on soon.

I’m also going down to 18’s if anyone is interested in the 22’s on my 2018 Platinum. I’m lifting and outfitting it for some moderate trail riding.

Your style wheel were the ones I wanted to get but couldn’t find any in my price range. That is why I had to settle on 20’s for now and put the 18’s in the garage.

Yep, I also prefer the 2018 Platinum wheels over the newer ones. They are beautiful.
If I were never going off-road I would definitely keep them.

Use https://www.willtheyfit.com to determine proper tire size when changing wheel diameter. It'll even show you a percentage of speedometer error.

If going down to 18" wheels, 275/65 R18 tire will come closest with 0.07% difference in speedometer error.

Tom Brennan, use this tire size calculator to compare your old size (22”) to the new tire size you would like to switch to (17, 18, etc). It’ll show you all the dimensions of each tire, AND how it will affect your speedometer. It allows to plug in numbers until you find the right combination that fits your needs. Select the tire comparison tab to begin. https://tiresize.com/calculator/
