I have a 2015 denali 2500. I'm leveled and running kryptonite UCA's. Currently running 20x10 wheels with 33x12.5x20 tires. I just picked up some stock 20" denali wheels and got a great deal on some 295/65/20 ridge grapplers.

My question is will I be able to run these without a lot of rubbing? My main concern is rubbing on the control arms. Thanks for any input!

Did you ever try this out or find an answer? That's the setup I'm wanting on my 2018 but want to know before I spend any money.

No you will not be able to run those without rubbing on the UCA. You will need wheel spacers.

You sure @denarli6.6? I'm almost positive I ran that setup on my 2015 without issue.

Yea I am tryin to find where i saw it at where they referenced exactly the thickness of the wheel spacer they had to run for it not to rub.

Yeah I did it. And yes it does rub on the control arm at full turn. That’s the only place it rubs. 1/4” spacer should fix it. But man it looks great.

Now that I think about it, I did have 3/16 or 1/4" spacers that I ran to keep them from rubbing either the UCAs or the frame at full lock.
