I run a slightly bigger size on my stock 2020 1500 Limited (275/70R18) and I get a very slight rubbing if I have the tires cranked and I'm backing up.

Here's what they look like

I've been running 285/65/20 BFG KO2's at 40 psi on stock rims for past 5 years. No issues at all.

I’m running 275/65-20 on stock 2017 alloys with no issues. I do have the bils but they’re only set for.7” lift. I remember reading on here that they are no issue at stock height. Mine are heavy E rated which I chose after I had a rock puncture my tread on stock tires. Ride is still just as crappy. Maybe because I changed to cast iron control arms?

DanRob, you should also know that the 275/65-20 doesn’t actually measure 34”. It’s barely over 33”. I found this out when I went to calibrate my speedometer using supertuner. I think I ended up calibrated at 33.25”. Apparently tire measurements are all goofed up. I will say that I do like the taller sidewall vs the 275/60-20

I went with that size so I could get an E rated tire for towing, and for more plies to reduce chance of punctures/blowouts. I run 60 psi. This truck rides so well, the higher psi doesn't bother me. They are 34.21" tires. Since putting new rims on, I get slight rubbing at full turn, and this is with a 2" level. I have Cooper ATP's, and have almost 80k on them with several thousand miles to go before I need to think about replacing. In fact, there is still so much tread left I wouldn't hesitate keeping them on for a whole northern winter season. Great tires! And when it's time for these to be replaced, the same ones are going on. Excellent wear. Excellent traction. Ride is great for an E-rated tire. Not too noisy. And price is better than BFGs or many other all-terrain tires. Warranty is better than most, as well. And I blew well past the 55k warranty!

They look good, but actually 1" smaller. Extra inch of sidewall, but 2" less rim.

https://www.bfgoodrichtires.com/tires/all-terrain/all-terrain-t-a-ko2.html if you click on 275/65-20 it states 34.1. The 275 60 20 or stock size on 20s is 33. The metrics run pretty true to size. The imperials like the 35x12.50 are a bit undersized. Bfg for example claims 34.5 for theirs.
