Biggest tire size - no lift

[Intimidator3]

Looking to replace the tires on my Avy and want to get something a little more aggressive. Currently have 20s but will probably upgrade to 22s. What's the biggest tire I can run without leveling? I did a little research and it looks like Felix was running a 305/40/22 before he leveled. I'm looking at terra grapplers right now but am open to other suggestions. Hankook dynapro ATMs are nice but it looks like they only come in 305/45/22. Too big? I should also note that I do zero off-roading. The truck is mainly highway driven.

Also, what's your thoughts on running CK375s on both my Tahoe and Avy? Too much of one wheel?

Thanks

did you decide on tires? i would like to see pics if you did.
also, is your truck currently lowered in your sig?

Im running 275/60/20 lowered 1.5/3, was running 305/45/22 before that at the same height. If youre stock height you wont really have any rubbing, I didnt have any rubbing at stock height until I lowered it, and then it was just fender liners. Heated up and remolded the front, cut the rears slightly and its all good now.

what offset are your wheels at?

On my '12 Avalanche I had 305/50/20 Terra Grappler G2's on stock wheels and suspension about 8 weeks ago. Zero rubbing on the fronts and that includes minor off roading with the snows we've had here. Occasionally, the rear's slightly rub backing out of our sloped driveway if I approach it at just the right angle but it's not anything that cannot be fixed with a heat gun (I just have to get around to doing it).
