275/65/20 2020 Sierra

[joey1234]

Looking to put some new shoes on my 2020 Sierra 1500 SLT here. I have a 2" rough country leveling  kit and want to see if BFG KO2 275/65/20 will fit without any rub. Im assuming they will fit just fine but before I buy them want o ensure. 

Thanks

Looks like some of those cats are running 295/60/20 Nitto Trail which is a 34.5 tire and has no rub so a true 34.1 should be fine?

275/65/20 is standard sized on 20" wheels from the Factory with AT4 and Trail Boss - I have AT4 - plenty of room - don't think the 2" of Factory lift makes any difference in how they will fit.

275/60R20 AKA"33inch" is the largest factory size

I have the same truck and lift. 285/65/20 rub bad.  You will probably have minor rubbing with 275/65/20 since it’s still a 34” tire. I’d go 285/60/20 if I could do it again. 
 

let us know how it works for you.

I went with the 275/65/20 Ko2 so we will see look to be a 34.1. when measured it will fit but I guess we will see.

How did they fit? I am looking to put the same size on my Sierra with a 2 inch level.

For what it’s worth, I have a 21 Silverado Ltz stock suspension and it came from factory with 275/60R20 Goodyear wranglers

I have a 2019 Z71 RST with a 2.5" level and 20x9 0 offset mayhem wheels. I had 285 55 20 AMP Attack pro on there and no issues at all. I replaced them today with 275 65 20 Cooper discoverer AT/3 XLT today and had to minor trim the mudflap on the front. Had a small amount of rubbing at full lock in reverse.

2020 GMC Sierra with leveling Kit and I was able to fit the 275/65/20 Ko2s no rubbing no issues. Was skeptical at first but did a test fit and was surprised how much clearance there was compared to previous models

4” lift and 285/65/20

Hello, I’m thinking of doing the same. Mind telling me what leveling kit you used? Also, do you think the tires would clear without the leveling kit?

 

thanks!

Not really sure what brand leveling kit it was, I took it to a local shop who does all my suspension work but if I’m not mistaken it was just a plain leveling kit, but stock it will not fit this truck
