Thanks Axe. Very helpful. Guess I'll either stick with what I have or go with 37x12.5. How much of a spacer do you think a guy would need to clear that UCA. Not a fan of spacers, just considering options.I've tested 37s. They will work, but limiting factor is clearance between UCA and tire. With stock offset, the tire is already close. Larger tires make it very close. Need wheels with 0 or -12 offset in my opinion, especially if they are 9+ inch wide rims.
You can see the photos and info here.
37s on AEV 18x9 Wheels
I was doing some test fitting of some 37x13.5R18 Toyo MTs. It looks pretty good and more aggressive. Fills the wheel well up pretty well and has plenty of clearance front and rear in the wheel well. The problem I was concerned with is that these wheels have 0 offset, maybe positive offset, so...www.chevyzr2.com
You could actually run the setup I tested if your not airing down or heavy offroad where you get a lot of deflection. Too close for my liking.Thanks Axe. Very helpful.

Yes 13.5s, as part of my objective was to get a wider stance. Also want a balance between proportions height to width.Nittos 37x11.5s might serve well here. How wide is the ZR2 wheel? I'm assuming 9 to 9.5. I have all the ZR2 suspension parts (sans the hard to find knuckles) and am converting over soon but am going to be using Alaskan edition 18x8s.
Axe, from what I saw didn't you try 13.5s?
Thanks.
I live in the Sonoran desert, so my rig doent see much snow.37/12.5/18 nitto fits fine with zero issues around the upper control Arm. At 40 psi almost 1.5 inches of clearance. The toyo mt is still a good tire but is out dated now, on my 2008 3500hd I run a maxxis MT 38 inch that make less noise than the toyo and tow my 15k excavator great. Another good pick is the mickey thompson MT. I moved away from the toyo mt because of the terrible snow performance.
