2 cents on tire rubbing

[GreatDaneHummer]

Gentlemen and Ladies,

I have read and heard so many times the age old question for Hummer owners; "What is the maximum size tire I can run with no rubbing"... I thought I would add my 2 cents in on this and say there is no perfect answer. Before you get all up in arms think of it this way. Every tire is made differently and with the many differences the only way to definitively answer this question is braking it down by individual tires. So I thought I would start us out from my personal experience. Please do not post up anything that you cannot 110% promise you have seen with your own eyes.

STOCK HUMMER = Not lifted / Not leveled
LEVELED = Lifted 2.5" front / 1" rear
LIFTED = 3"+ front / 2"+ rear

Define Rubbing: Full tilt left and right does it touch anything!

- Mickey Thompson Baja Claw 315/75/16 : STOCK RUBS / LEVELED RUBS

- Goodyear Wrangler Duratrac 285/75/16 : STOCK NO RUB

How are you accomplishing a 1" rear lift on a leveled rig? Rearch? Extended shackles? Is 2.5" even possible in the front without shredding half shafts?

Leveled - rubs with BFG KO A/T 295/75-16, BFG KM2 305/70-16, Hankook MT 315/75-16. Sway bar is nice and shiny

Rubbing really isn't that much of an issue at full lock, just back off a tad. Granted I've got a 2, but my stock tires rubbed at full lock. No biggie

Mine rub a little at full lock only! I just bought TOYO 315/12.5/17T ... Not really anything to worry about, i suppose? In fact, the truck rides nice with the big tires on it..

To answer your question accurately it would not be perfectly "leveled". Most of the leveling kits on the market IE: Rough Country provide extended shackles. Yes I currently run 2.5" in the front with no issues at all. I have done "Bulletproofsteering" upgrade to correct for it but it wasn't needed. To raise my rear I put on Old Man Emo leaf springs with extended shackles. Really not the point of the thread though. I was trying to help with the tire rubbing discussion.

Stock, no rubbing on 285/75r16 Duratracs.
Stock, no rubbing on 285/75r16 Nitto Terra Graplers
Stock, light rub on 315/75r16 Kelly Safari TSR
Cranked t-bars, heavy rubbing on 315/75r16 Kelly Safari TSR
Cranked t-bars and shackles, light rub on 285/75r16 Duratracs
Cranked t-bars and shackles, heavy rubbing on 315/75r16

IMO, the side-biters on the shoulder and sidewall of the tire make a big difference in amount of rub, but stock t-bars seems to have the least rub on anything. Based off observations on our 2 H3's.

35" KM2s on stock wheels (315/75r16). TB crank leveled, rubs sway bar in front, rub fenders when fully articulated (partially ripped out front portion of front fenders while backing off an obstacle at full articulation. Also rubbed upper portion of rear fenders when fully articulated. 1" body lift fixed rubbing in fenders but still have shiny spot on front sway bar.

Thanks. I think a lot of folks just crank the torsion bars to 23.5 and call that leveled. Back to the topic. Hijack over.
