Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Will 37/12.50/17's fit on a stock H2?

I wasn't sure if the previous owner re-geared the H2 or not, but she didn't struggle at all going up steep hills and overpasses.
Okay, got it. Your question was more about gearing, drivability, etc. I've done no regearing and she drives perfect, everywhere.

Sorry to bother you. Happy Memorial Day holiday. With those 37 inch tires, do you experience any shifting issues with the transmission?

None I can think of.

Thanks, for the feedback. I think I'll try the 37inch tires on my H2. Hopefully, she can handle that size with little to no issues.

Didn't re-gear putting the 37" on the 2008 with 6 speed. It feels slightly slower, but really that's only if you're looking for it. I do want to get a tune added to adjust for the different tire size, which should adjust transmission shift points and correct the speedometer. But if you didn't do any of that, it's just fine.

Thanks. I appreciate the feedback. I just don't want to go too big of a tire to the point where I adversely affect the transmission. I made a similar mistake when I lifted a FJ Cruiser over a decade ago. I put 35's on her, which caused the tranny to steady hunt for gears, even on flat road surfaces.
