I searched online and saw a lot of trucks that were either lifted, had a leveling kit, or used spacers. My truck is completely stock with the original 20" wheels on my 2016 FX4 XLT. I found a great deal on some 275/60-20 tires, but from what I found, they are about an inch taller than the 275/55. Besides the speedometer being a bit off, will there be any rubbing problems if I use the larger tires on my stock F150?

No problems at all. A lot of people, including myself, have used that size on a completely stock truck without any issues.
Same. Got a great deal on 275/60-20’s and have no issues. Stock suspension. Speedometer is about 2 mph off at 80mph, but no other issues.
I just put these on my stock 2017 FX4 Platinum with factory 20s. No issues at all. The speedometer is 2 MPH off at 70 MPH. The tire isn’t an inch taller; it’s only 1 cm taller, which raises the truck by 5 mm. In my opinion, this is the tire the truck should have come with when it has 20-inch wheels. I believe it’s the factory size for the 14th-generation models.
275/60R20 is actually about an inch taller tire than 275/55R20. 33" and 31.9" respectively.
I just had 275/60 BFG KOs put on today. I was worried they’d still look too small since the 275/55s are really tiny, but I was wrong. They look perfect, just the OEM+ look I wanted, and they’re still load range D, so the ride quality stayed the same. It’s a great choice.
That’s the main point. This is the biggest size that still uses P-rated tires. If you go bigger, you’ll need heavy-duty tires that are much stiffer to ride on.
I did this same swap myself about a month ago. I found a set of 2022 Sport 275/60/20 tires and dark gray Sport rims. I sold my lighter gray Sport rims and 275/55/20 tires on Facebook Marketplace in about 30 minutes.
I used Forscan to fix the speedometer, so it’s accurate now.
The difference between LR D and LR E is max inflation and load capacity at that max inflation. At the 45-ish PSI you’d run in a half ton you’d never tell the difference.
I heard from several people here that 275/65-20 tires will fit without needing a lift, spacers, or new wheels. (This is a 34-inch tire.)
The downside is that these tires are heavy because most of them are load range E. There might be a few Nitto tires in this size that aren’t in the LT category.
E load tires are stiffer than D load tires at the same tire pressure, and they’re also much heavier. This extra weight isn’t supported by the suspension, so you’ll notice a difference when driving.
Fortunately, 275/60R20 tires are usually P-rated, but many companies also make D and E-rated versions. If you’re worried about weight and ride comfort, choose a P-rated tire.
