tire height

[timgco]

So I have talked with a couple people on this already and got some good replies, burt thought I would make this public to see if anyone else has ran into this.

I have 35 12.50 18 BFG MT's with 18 x 9 rims.

I have 1.25" of clearance left to hitting the garage frame (not the rubber flap that sits lower yet).

I want to go to 37's, but I know there will be around a 2" higher if I stick with the same rims. The tires I currently have a worn down good. They measure 34" in their current state.

the procomps i want to switch to are 37's (36.8" high is what their web states). Si I would be raising the vehicle height by 2.8" if this is correct.
And that won't fit!

Do you think I can make this work if I switch to a 17" rim? The reason I ask: I looked at older pics of my past H2's with 37's on the stock rims. There was more sidewall buldge on the 37 x 12.50 x 17 bfg mt tires. They all fit in the garage, but the past H2 all had air susp. This one does not and sits higher in the rear of the vehicle. Do you think the 37's on a 17" rim will have more sidewall buldge to make this fit?

Oh yeah,(for you smart a$$es) parking outside or airing down to fit in the garage is not an option.

Procomp Extreme AT's 37 13.50 17 or 18 is what I'm after.
