Topic: Thinking about going from 37's to 35's

[aw12345]

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

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.  On the highway the gearing should be pretty peppy. I might even get a speeding ticket

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.

  Crap man, most towbars are only rated at 45-55 MPH.

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?

[TahoeYJ]

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?

EDIT Tahoe  you need to change your sig 





Picked them up Monday, went wheeling on Tuesday  
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...
