265/70/r17 vs 275/60/r20

I'm about to pickup a new work truck in a few weeks. Going from a '23 XL 2.7L to a '25 XL powerboost. My company is very relaxed and this is my only vehicle, I can use it for whatever, whenever (to an extent).
The one question I had was the tire size that comes on the '25 I'm about to pickup.
My current truck has 275/60/r20s. Just got some nice Conti terraincontacts put on about 10K miles ago.
The new one will come with 265/70/r17s. Don't know what brand of tires I'll get on the new one.

Will there be a noticeable difference in ride or handling? There's a 1.4" height difference between the tire sizes.
I've heard that I can ask the dealer I'm picking up from if they will swap the wheels from my previous truck to the new one. I believe others have done this on their fleet trucks. Besides the look of the 20" wheel, is there a reason to keep the larger wheel/tire combo?
Just curious on what you would do.
Would I also have to find a way to reprogram the speedometer if I changed tire size height?

XL PB unicorn fleet vehicle! Didn't realize they put 17s on them. Going from a 2.7 to a PB, you will notice the additional 550lbs, as to how w/ that wheel/tire combo, not sure. Do report back.

Are the XL PBs 4x4 only as well? You'll love the truck vs the 2.7. Lots of power.

It was interesting because we had 2 F-150 options: 2.7L XLT or 3.5L powerboost XL w/104A package.
The 104A package actually makes it nicer than the lowest package XLT... so no brainer.

Not sure if the XL PB is only 4x4, I didn't have a choice based on where I live. I'll have to ask our guys in Texas if they got 4x2 or 4x4 on theirs.
I am excited to pick it up! Basically an upgrade all around from the STX XL I have now.

When you get the truck, do share pics! XL PB last year was 23

Here's the infamous '25 XL PB. I was able to swap the wheels to it from the '23 STX I was trading in. Looks much better than the 17" ones it came with.
