Yes lots of rubbing. I did all the fender mods without cutting metal to make them fit.

2” RC level, 1” block 285/65/20 BFG KO2

I’m getting vibration with my new tires around 70 mph. Bfg ko2 285/65/20. 2 balances and still have it. Didn’t notice it before. 2019 gmc crew

I’ll save you some trouble. I put this size on my Sierra with a 2” level and could hardly turn without major running. I ended up heavily modding the fender wells and made them fit but it was a pain. I’d go 286/60/20 on a stock AT4

What kind of lift do you have? Looks great.

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.

They are the AVS ones, I had some trouble with the edges stopping the window so I super glued the edges in place in the channel and have worked great since. I am hitting that same bolt head so not much I can do except take it out I suppose.

Your not gonna have a lot of options without a level or doing the fender support removal. The gmc fender wheel is narrower than the Chevy and previous years. I am running 286/65/20 bfg at’s with both of the aforementioned mods and still rub.

Thank you for the feedback, that is very helpful. Do you mind sharing a picture?

Need some help, I just installed 285/65/20 BFG KO2’s on my 209 Sierra with 2” level and they are rubbing the mud flap and back fender well bad. I removed the bracket and pulled back the fender liner but still rub more than I want. I think I am going to switch to a 285/60/20 or a 275/65/20. Does anyone have experience with these sizes on a Sierra? I want zero run and not willing to cut the mud flap. I appreciate any help.

Just got 285/65/20 ko2’s on my Sierra with 2” level and they rub the rock guard bad. Think I’m going back to stock size.

I just put on 286/65/20 BFG KO2 with a 2” RC level and it runs the mud flap pretty bad.

Has anyone tried these? Just put on new tires and rubbing right at the mud flap.

Anybody have this kit installed yet?
