I got some 20" wheels from an Expedition. I dont really like the 18's that came on the truck, but Im not sure I want to mess with the speedometer, TPMS, etc. What are your thoughts? (the orange things are my wife's arm weights holding the wheel off the ground if your wondering).

 

Looks good, speedo is easy with Forscan And your tire shop should be able to install the TPMS rebuild kit when they mount 5he tires.

 

Be prepared for a somewhat harsher ride. At least, that was my experience, YMMV. I love the look of my 20s, but the 18s rode much, much better. If you go with the 20s, you may want to invest in some better aftermarket shocks. You may already know all of this, and if so, enjoy your new wheels/tires.

 

You won't have to mess with anything if the new 20" tire diameter is the same as the 18" tire diameter thats on the truck now.

 

Expedition wheels look much better imo. So long as you stick with oem tire sizing, the overall tire circumference should not change (going from an 18" rim with 32" tire to a 20" rim with a 32" tire). You won't have to do any other speedometer work.

If you do go with something much bigger than a 32" tire and you do wish to change it, it's easy with forscan as Arsenal11 mentioned.

 

I like them. I'd put them on the truck.

 

The new tire will be larger. The stock tires are 265/60/18 and the new ones would be 275/55/20. So the new tire will be 1.4" taller

 

dang...thats the reason I bought a 2wd, for a better ride.

 

I get it. My current truck is a 2018 STX SCREW 2WD on 20s. My 2013 XLT SCREW 2WD rode smoothly on stock 18s. Less so for the OEM 20s I have on my current truck, so much so that I put Bilstein 5100 shocks on the rear to help smooth out the bumps. While I did put another set of OEM 20s on my current truck, the ride quality did not change until I put on the Bilsteins. It was still jittery over bumps, especially in the rear. Now having said that, I don't know what suspension bits are different from the factory with respect to 18 and 20 inch wheel setups and the tires paired with them. I didn't go from 18s to 20s on the same truck, just comparing stock 2013 (18s) to stock 2018 (20s). You could test drive an STX and see if you notice any difference. If you do, find some RR tracks or some less than ideal paved roads. But, honestly, it didn't take much to make the rear end of my truck hop and skip with the standard 20" set up.

 

He’s probably comparing a 275/65/18 (so a 65 series sidewall) to a 275/55/20 (a 55 series sidewall). The difference between your 60 and 55 will be less than the difference between the 65 and the 55.
