Been on the fence about this for some time. I am overall happy with the 37's. Gearing wise and pretty much all the way around. Problem is there is not much in the way of choices for new ones or if I ruin one.
My tires still have enough meat where I can get a few dollars for them. So I'm thinking try and sell and replace with 35 inch KM2.
One of the drawbacks is since I moved the rear axle back the frame spring hanger is a rock magnet! The larger tire helps not get hung up so much. But all the trails I run a 35 will do just fine.

36's 8)
-
Honestly, I think 35's are probably my limit. 35's are more common which is nice. Also, by going smaller you can increase the trail difficulty a bit without having to do harder trails.
How about making larger skids for the spring hangers?
-
There's a little room to move the leaf spring eye up in the hanger and shave the hanger. Also seen some sweet frenched spring hangers in some of the 4wd mags.
There is such a large price gap once you get over 35" tires, that prolly limits a lot of wheelers.
-
Scott since a lot of tires run small including the old MTR's you could always go for a set of 35" krawlers and get pretty close to where you are at now. Those things are true to size. Also they are a pretty darn good tire for the rocky stuff, very little worries about cutting sidewalls and excellent traction

I did trim the hanger back a bit. With 37's it's about the same as a non trimmed with 35's. I thought about frenching it but don't feel like messing with the pinion angle. I have seen where people have moved the hole up a bit and trimmed the hanger even more.

Krawlers are a nice tire but HEAVY! Plus I don't trailer so I don't think they will last all that long.

For the trails I do I pretty much walk right thru stuff. So a 35 should make it a little more tough. I like the idea of having a common tire and size. I have been real lucky and have only put a hole in a side wall once. But you never know. Having a tire that is not in production or having few choices for replacement is not a good feeling.
-
I would move the hole up as much as the spring eye/frame clearance will allow. Your cutting didn't save you much, and looks like it would hang you up pretty hard when you catch on something. The stock hanger would have been angled more to help you up and over and not get hung up solid on an obstacle.

How much does say a inch if it's possible affect pinion angle?
You can see where I keep getting caught towards the bottom.
-
If you raise the bolt one inch you will lose 1/2 inch of lift at the frame over the axle and the bolt will be only about 1/2 inch higher off the ground. So if you french, you should consider doing both front and rear unless the front is already lower than the rear and you want to level the Jeep. And also, it you use shims to set the pinion angle when SUA, this will also reduce the lift a bit.

I'm not to worried about the loss in height.
Pinion angle shims are bad. I'd live with the vibes, or cut the perches and move them, or a bit longer shackle to fix before I did shims.
-
You know instead of cutting the hanger back you could have also lengthened it. This would decrease the angle at the front of the hanger so rocks would slide on it rather then getting caught up on it.

My thinking was to have less so it won't touch. I can see where a longer one will act more as a ramp. But from what I have seen if it touches it will hang up ,no matter what the angle.
-
Welp, a potential buyer is supposed to come over this weekend to look at my tires.
I need to find out how soon I can get some KM2's. I guess they are not avail for some time.
What else is worth looking at besides the MTR Kevlar?
-
Truxxus MT's?
-
I was thinking the same idea of a small ramp. You could look into adding roller blade wheels/rv roller as part of it as well. Before all the trends of today's articulating and soft riding 4wds, the old school leafed 4wds used rollers outside the front shackles when approaching obstacles here in Moab.
Looks like you'll have to redesign the mounts for the size tire you'll be running, ie just like you did with the 37's. Too bad you can't get up in wheel size.
Another tire option is the Cooper STTs. They have 35s in 15s.
-
I would hunt around for the new MTR's, a friend of mine just had a set put on so they ought to be available somewhere
-
I'd go with the Cooper STT, great tire. The MT/R seems overpriced and overrated, just like the old MT/R it replaced.
I ordered a set of 35" BFG KM2's yesterday, the tire wholesaler had one set of 4 in stock and they'll be in Monday :hump:
-
Truxxus MT's?
They have those in 37's. I'd like to stay away from that brand. I drive on the street to much. I've read some real good reviews and some real bad ones. I wish it was more consistant.

That is my 2nd choice. I have seen and read where lots of people are having a easy time of popping the sidewalls.

I have heard the Cooper STT is a nice tire. I have not seen anyone run it.
I think I'll hold out and wait for the KM2. I don't use my Jeep for weeks on end so if it sits on jackstands for a while it's not that big of a deal.
Besides I like the fact BFG donates money to keep the trails open!

Looks like there is a $60 rebate on the BFG's and $80 on the MTR. Just a FYI.
-
www.4wd.com has $69 shipping right now on 35" BFG tires, might see if they have some in stock. My local shop matched the best price I found online and included mounting/balancing.

I called America's/discount tire. They will take the old ones off for free. They are going to match price of $208 ea. Plus I get the $60 rebate. I like to buy from them for their replacement warranty. It can't be beat!
This is the first time in about 12-13 years I have bought brand new tires for the Jeep. 33's-35's-37's all used.
They should be here sometime next week. (fingers crossed).
-
I had cooper stt's not bad offroad, had a hell of a time to ever get them balanced and just like procomp tires they have thin sidewalls. Cost wise they where close to MTR's the last time I looked
-
+1 Goodyear mtr's over rated
-
When I look into those tire prices....makes me wish I lived in the US :fitz:
31x10.5-15 BFG's Km2 are 300USD each one down here
-
I've had the Trxxus MT's on my rig for more than two years. I rotate and balnce for free a couple of times a year and love them...on road and off.

interco has some nice stuff thats for sure
how do they hold up for wear I know the swamper boggers don't last for wear

What is the used tire market like? Any 4x4 clubs or forums that you can look at for used stuff?

I thought about those in a 37. But I have read so many conflicting stuff on them I choose to go with a tire that had great reviews all the way around.
Glad they are working out for you. They do look nice.
-
The Truxus MT's I had on my XJ were terrible. Cupped very badly, impossible to balance, noisy as hell. Never took them offroad before I sold them though, probably do pretty good on the trail. Dunlop Mud Rovers are the best all around tire I've run for the money. Sidewalls were a tad thin but that was my only complaint.

Waiting for my new junk to show up.

All I can say that if you do not daily drive it go 35" krawlers, excellent rock tires and tough as nails. Just tried mine out today, besides being noisy as heck I am very happy with them. No real noticeable difference in power that I can tell even though they are close to 2" taller than my 35" MTZ's, doesn't seem to hurt milage all that bad either.
For the rocky stuff MTR's or Krawlers are the ticket unless you like replacing tires with cut sidewalls

The Krawler looks like a nice tire. I need something more quite. I grooved my old MTR's and they were real loud.
I have KM2's coming. I bought the America's tire replacement plan. If I start going thru them due to trail damage I'll replace them one by one with something else.
The new MTR just has not grown on me. I don't care for the look at all. I don't like the white lettering, yes you can run them black out but still. There are a number of guy's in my club that run them and seem to be happy with them. Only 1 guy is running the KMs on Isham he seemed to do fine. Another guy has 2 KM2 and 2 old MTR's he is slowly getting the MTR's off.
I guess time will tell. I do a fair amount of rocky stuff for sure. I'll be sure to bring my plug kit :thumb:
-
On the plus side the tires you bought seem to bite pretty good on rocks, from what I have seen so far. The new MTR's look a bit goofy but seem to work very well on rocks
and also run big for a 35. It's a tire that works well for rock crawling in spite of it's looks. Because of the funny pattern it might actually run quiet for most of it's life unlike a lot of other tires that start out fairly quiet and get a lot louder as they wear
-
On the tire thing, this is the thing that has had me vexed ever since my Jeep was 3 months old. Stock tires drove straight, BFG all terrains no lift pulled to the right, lifted it still pulled to the right, changed tires to 33" copper stt's pulled to the left with no change to anything. Switched to 32" goodyear MTR's still pulled to the left, changed to 35" Mk MTZ's still pulled to the left, changed front axle adjusted and centered everything still pulled to the left, changed to 34" Krawlers with no other change than swapping tires it goes straight with a very slight wander to the right. You go figure that one, must be a Jeep thing, it has me stumped

I am sure they improved them over the old style. They look like they would be a fairly quite tire on the road. Those that I know running them seem happy with them. Who knows maybe it will grow on me by the time I need a new set. I know when GY switched from their MT to the MT/R I did not like the looks of the MT/R, so who knows.
On a side note I also like the fact BFG donates money or used to to help keep trails open. I wish more MFGer's would do that!
-
That is very true BFG is quite active in the offroad business and do a lot towards trail awareness and such. I guess the 35" might just put a lot of the fun and challenge back in wheeling. Should make the last part of the Dusy more fun, I really wanted to turn around at the end and run the last part the other way also, I guess we will save that for the next trip and Swamp lake.

Very true it did turn into a point and shoot kinda thing. Another bonus is not stressing the drivetrain so much. I was real worried about snapping a rear shaft. Infact I was pricing the 35 spline shafts and a 35 spline ARB. Mileage might improve a tad also. Looks like I get to monkey around with getting my speedo to read correct. I will also swap out the longer bump stops in the front for the stock size ones. I should get a bit more flex out of the old girl!
Plus in low-low first I go from 35 feet per minute to 33 FPM. :lol: On the highway the gearing should be pretty peppy. I might even get a speeding ticket :roflol:
-
You can always flat tow it lol, that is the only time my Jeep hit 100mph going downhill behind my Frontier coming back from Moab. 100 downhil 20 uphill lol.
The beastie will do 85 if I really stomp on it and cruises pretty nice at 70-75.
We will see how the other one will do with those big round flotation devices, kinda curious how well it will drive on the street.

One thing is that the non-directional tread patterns do slope opposite ways on the outside (and inside) edges for example when viewed from the front. It would be interesting to see if the different pulls corresponded to opposite slopes and if a directional tire like the Baja Claw would drive straight.
A quick check just now showed that the MTZ and Krawler slope in opposite directions. Haven't checked the others.

We are going to run Swamp Lake with my daughter, then a few weeks later my dad is going to run Dusy with me. He is driving down from Portland. PM me with you dates. Are you gonna do the Dusy then go and hit Swamp?
-
Have you gotten them yet?
they're honestly pretty damn quiet on road, I've been driving an average of like 45-50 miles a day on mine and the more I drive the more I like 'em. I still wish the MT/R's would have come in so I could have given them a go but I'm happy as hell with the KM2's.
What made you go back to 35's? Was it just because there's really not a lot of streetable tires in a 37X12.5X15?

Picked them up Monday, went wheeling on Tuesday :doggy:
Like what others have said about them they are quite on the street. With just one fairly easy trail done they seemed to work great.
I don't like the looks of the Kevlar MT/R.
Ya pretty much the lack of tire choices for a 37 in a 15 inch wheel. I wish I could have stayed on a 37 but for the most part I really didn't/don't need to be on a 37. Plus I found someone local to buy my old tires so I thought it was a good time to sell them while they were in fairly good shape. I was really afraid of ruining one and not having a way of replacing it. I know there are still some tires out there used. Infact I looked at a set of darn near new 37 MTR's but the beads were tore and I wouldn't want to run 3 torn beads. So I thought that was a sign to get out of mine while I still could. And a brand new set of 5 35's cost me about half price after selling my 37's.
-
Really surprised how quiet my 35" KM2's are on the road. Mine won't see much trail use, the TSL's are tougher.

They get a little bit louder as they wear a bit, but nothing to write home about...

Lol yes, yes I do. I actually haven't had the MT/R's for almost a year anyway! :pirate: just been too lazy to change it. Never pay attention to it either.
I dig how quiet they are, every time I drive my Jeep I think about how nice it is to have quiet tires with the top off. I'm young butI hate loud, but I do like loud music :smokes:
I've only done a hill climb in 2WD on my friend's property and that's all mine have seen off paved roads so far but they had damn good traction going up hill. I was actually rather surprised I made it...
-
The Jeep looks good on 35's and you have lots of fender clearance now and more flex.
