tire height

[dochummer]

Hmm..., if you're current tire diameter is 34" and you're moving up to a 36.8" diameter tire, that should only increase your total height by 1.4". Isn't that the way it's supposed to work? So, you still won't be able to fit because that's .15" too high. But, if the 36.8" is not the true height, and it's actually lower, then you'll be fine. Did you say that you don't have the air suspension now? Then, just throw a couple of salt bags in the back to weight it down until your tires wear down enough to fit into the garage without the extra weight.

Have you already adjusted the garage door to make sure it goes all the way up?

It's the actual frame that's there. My door is up out of the way. I looked at rasing it up a little. I may be able to get another 1" if I remove one trim part and get a longer rubber flap for the seal. But that may not work. I have to have someone take a look at it.

Tim, how high is your garage threshold or frame or whatever the technical term is?

I was thinking of doing 37's aswell. I was unsure of what the add would be to the height. My opening is 83.5" and I have the roll up door is set at 86.5". I figured worst case, I would remove the roof rack bars.

I modifed my garage opening as you're describing. Your door is probably fine/tall enough and a standard 84" Door. I removed one trim piece to gain about 7/8" of clearance. With 37's the stealth rack just clears the weather stripping. I still need to paint the door top that is now exposed, but it turned out nice.

Tim,
If you have 1.25" of clearance now and you want to go from a 35" to a 37" tire it will only raise your veh. by 1", so it "should" fit. (When you figure the radius of a circle or tire, if it's 2" taller, 1" is on the bottom and 1" is on the top. If you went to a 4" higher tire it would only raise your hummer by 2", etc.) The thing you have to be careful of is what the actual diameter of the tire is. You really need to go measure the tire you want to buy. Example: a BFG mud terrain that they measure as a 35" tire is actually only 33" in diameter. Conversely when you measure a Toyo tire when they say it's 37" in diameter it is actually 36.5". It all depends on which company makes the tire. I can tell you this: I just changed over from 35x12.5x17 BFG's to 37x13.5x17 Toyo M/T's and before I had about 2 1/2" of clearance. Now I have about 1/4" clearance. I just barely squeak that baby in now, but it fits and that's all that counts. Bottom line is your gonna have to measure the tire yourself, do the math and hope for the best. Les Shwaub Tires let me take the Hummer home with the new tires to see if it fit in the garage and if it didn't they offered to take the 37"s back and change me over to 35"s. Give it a try. Good luck.

Tim, you could alway load your truck up with wheeling supplies, parts, etc and that would lower the rear enough for you.

To be honest Ken, I liked your other avatar better.

I agree, the fake bootie is kind of well, fake.

I'll change it now.
