How important are 37" tires?

Can't you get 37" military surplus tires for cheaper than 35" tires?

Yes, Yes you can.

Maybe, but I like having a good ride on the highway.:meh:

I like having a good ride on the highway too, and my '37 surplus tires ride as nice on the highway as my Mickey Thompson MTZ's. They have even been more than just acceptable in the snow and ice. I think the MTZ's may arguably be a more agressive tread. I think of the hummer tires as a super agressive AT w/ really deep tread rather than a true MT. But that's just me.

It also made me sick when I punched a hole in the side of my MTZ w/ about 25% tread left, cause I didn't want to spend $300 on a single tire to replace it. Was cheaper to buy 4 - 37's (which I've damaged two so far, one with a tree, one with a nail in the sidewall). I was finally to the point in my wheeling that I was afraid I'd be damaging more tires and it was going to get expensive - guess I was right. If I had endless money, I'd go back to the MTZ's, but I don't, so I'll stick w/ my Hummers.
 
It's not just the cost of the 37s It's also the gears you will need. If you are running 37s with stock gears you're fooling yourself ( just try some really steep ascents and descents) I feel the gearing on mine is way too high and I'm only running 285s
 
2.5" lift and 4" BS'd rims. No rubbing.

i ran stock 4:10's and 37 inch swamper ssr's all the way through the con on my last 93 with no issues...just had to give her a little more skinny pedal

Your CEL is on. :hillbilly:

A little off topic but a little on topic, a compromise if you will, is there a good 36" radial option out there? I aware of an Interco bias ply 36", but I haven't seen or heard of a good 36" option.

used to be able to get a buckshot mudder in 305/85R16 I believe.

A better option might be something like the Interco Truxus - one of the few 35x12.5R16's out there - it's a legitimat 35" where as most 315's are more like 34-34.5"
 
Yes rock crawling is one thing, but steep hills are something entirely different

Actually 37's with 4:10 are a little better on the hills then 35's with 4:10. With 37's you down in 2nd gear at 65 with a RPM of ~3700. 35's at 65 in 2nd is ~4100 a little high without much headroom.

What did you not like about the 37"s? Mine has had them for about 70K miles with stock gears and prefer them in every way to the 295's that they replaced.

Eggactly, with the 37"s drop to second gear and climb, at 65+mph, setup perfectly for it. Unlike the 295's that wouldn't pull third, but would over rev, have to slow down in second.
 
Interesting that this thread should pop up now... I will soon install J's & long-travel shocks. I'm running older 33's now, and I've been grappling with the decision to stay on 33's when I replace these, or go to 35's. With 35's, I'd need 5 (for the spare), so the cost would be substantially more. I've been wondering how much real benefit a 35 adds when aired down, as compared to a 33 that's equally aired down; and whether that benefit offsets the lower performance on stock gears. Mine is a DD, driven to & from the trails, and occasionally loaded down on mountain roads. Decisions, decisions...

That doesn't make up for all of the nuns that would still be alive if you had stayed with 295's.

Sounds like where 37s really shine is on all out rock crawling type stuff. Since I'm going the expedition style route with my 80, 35s sound like they should be fine. As long as I can make it through Canyonlands...:steer:

Yer missin' the point. 37's shine at Starbucks. That's because when you look at your rig out the window sippin' on your latte you get a big shiny white smile on your face because your tires don't look like training wheels anymore.

You can tell a 37" guy from a 35" guy because the 37" guy isn't constantly walking around his 80 trying to find one visual angle that makes him happy that his tires actually look as big as they are.

35's are plenty of tire for the trails that an 80 is well suited to run without a material risk of body damage. 37's make those trails easier, but if you go up in trails as you go up in tire size you are going to start trail modding your 80.

37's satisfy like a Snickers. That's why these threads go on and on :flipoff2:

What hills have given you problems on 37"s?

Mine goes right up this. From the driver seat:
