I love those tires. Have them on my 17ATX. What would increasing the tire size do to your rear ratio? I would love to get bigger tires but don’t want to change the ratio for the worse

Stock wheels are 18x8.5" with a 24mm offset. They are not 18X9".

275/70/18, 275/65/18, 285/65/18 are the three safest that I can think of without needing more lift or trimming.

Per rough country on stock wheel 285/65/18 is the widest their kit is designed for http://www.roughcountry.com/gm-leveling-lift-kit-1307.html

I have a 2" lift all around and stock wheels and I put on 285/65r18 tires, Nitto RidgeGrapplers... I almost think I could go one size taller, but then it's an oddball size and your choices will be limited...

You think this new thread will give any different information? There is only so many tire sizes. I would take all the info you have gained and do a chart of those you know fit, those that may and those that won't with out trimming and decide what route you are willing to take. Each is different, where some swear up and down they fit a 34 with out rubbing others need to trim with a touch over a 33, so many factors. That's why searching, gathering info and taking time to decide is best and what sounds best here.

The biggest tire is probably a 35, are you willing to trim? Different tires are different sizes depending on type, shape, ect. So what may fit a light AT tire a MT might not at the same size and so forth...

You got a picture of your setup ?

Here are a few from when I picked it up at the dealer after they tossed on the lift and new tires. I think it came out just about perfect. Maybe somewhere down the line I will lift it some more, or try 1 size taller tires, even if it means then cutting the wheel well and installing color-matched fender flairs... But to me it has a good stance, decent clearance without it being too top-heavy looking and compromising the handling much...
