Hey Bud, thanks for posting this. Just want to ask, did you have to change out the stock wheels in order to fit those 275/70/18's? I'm almost certain my 18" wheels on my 2020 is different from those?.

Also a general question for everyone who sized up, is there a limit to what size may fit in the spare tire compartment?. I went with Tiki's size information and hope this wont be a problem with the spare. Thanks for any input.
No rubbing on the stock 18" LT wheels with the 275/70/18 K02's. Even on uneven terrain or at full lock in parking lots. I installed Bilstein 5100's in the front which help with that clearance.

I know this thread is a bit old but it was perfectly on point for me. Looking at putting 275/70/18's on my Yukon. This info was perfect. Thank you everyone!

Finally made it back to post a pic of mine. I also ended up putting in a 2" Rough Country lift when I put these on and I still get some rubbing on the mud flaps. Absolutely love the look though so worth the minor annoyance.

Well I finally got the tires mounted through Costco. I had tried lying to them that the wheels I was bringing them were off a 2500 silverado so that they'd not give me a hard time about the size difference. My hope was that they'd be so unaware of the 6-lug vs 8-lug difference that they would never know. I think the service manager at my local Costco Tire Center doesn't like me, so he went out of his way to look at the wheels and determine they weren't the right ones. They said they'd mount the tires and explicitly write on my "file" that they have no warranty through Costco. So good for them on protecting their giant corporation I guess, and at the end of the day it's whatever. I tried what I could, I can't be mad.View attachment 304725
I think the 275/70/18's look great! Fills out the wheel wells much better than the factory tires, and no rubbing even at full lock.
How’s the ride? Is it comfortable or rough on long highway drives

Rides great, nice and smooth. Towing with them is just fine, cruising at 88mph on interstate 15 for hours on end is also totally fine.
I'm actually on my second set of these BFG KO2's 275/70/18. Got 50k out of the first set.
Their performance in the snow is what's convinced me to stick with these tires.
