Hey all
Has anyone done or know anyone who has put 40s or 42s on a Hummer H2.

Does anyone have picture?
Any info on a how much lift?
Any info on if a new drive shaft is needed?

Thanks

BIG 2 DABANK, with the 38's,, are these 38x13.50are your rims offset? 4.25 - 4.50 backspacing? Are you experience any issues with the drive train or does it feel like the engine and drive train worker harder? Did you lose gas mileage?, about power? Are you please with the 38's or you feel you should have stayed with the 37s?

The tires are 38"x13.5"x18 Toyo MTR and the wheels are 18x9 with a -12mm offset (~4.53 backspace). Very slight rub on the frame rail at full lock, not any more than stock or even the 37s I had. I usually offload this thing pretty aggressively and have never had an issue at full compression of the suspension front or rear. I have 4.56 gears and do not experience any sluggishness or notice the drivetrain working any harder. The truck still has plenty of power. In fact I towed 6,500 lbs of flooring and trailer this morning. However, If I knew 8 or 9 years ago when I re-geared to 4.56 that I was going to eventually end up with 38s I would have went with 4.88 gears. But I have not wanted to change them because quite honestly its not that that noticeable over the 37s I had. As far as fuel mileage, thats a tough one, I really don't check anymore the truck has over 250,000 miles and gets me from A to B without issues. It has a custom performance tune, long tube headers, high flow cats, and a flow master exhaust, and I love the sound of the engine too much to worry about fuel mileage. I would probably say the mileage has suffered slightly because they are a heavier tire and more diameter to rotate. I drive about 40 to 50 miles most days and its been years since I reset the MPG on the DIC, but the truck stays at 11 mpg on the DIC.

I would never go back to 37s I think the proportions of the 38s on the H2 just look and feel right and the leveling kit is perfect for me because I did not want to go with a full lift kit. The truck is more than capable as its currently setup.
