I was running 34" MTR w/k on my JKU for about 6000 miles when I came across a deal on four 35" KM2s. Soooo, I installed the brand new KM2s. ($980 inc. mounting and balancing) The jeep felt like it rolled a little easier and noticed it didn't downshift as quickly on a particular hill and went back into OD sooner. With the MTRs the highway mpg was a bit over 18 on the computer. Today I made a trip that included elevation changes from 3500' up to 4500 and down to 2500' and then the return trip. There was no wind in either direction. The computer indicated 19.5 mpg for the trip. I'm sure both numbers would be lower with actual fuel used for miles driven, but it indicates a gain from the KM2s. I didn't buy them for that reason, but I can definitly feel the difference and they are slightly quieter.

Another difference is in the body width. The tread width is pretty much the same between the 34" MTR and the 35" KM2, and the KM2 is about .8" taller, but the body width of the KM2 is narrower giving me more clearance for the rear sway bar links when extended. The ride @ 30 psi of the KM2 is "slightly" better than the MTR.

My comparison was run @ 30 psi and 62 mph. I think they are both great tires. I went for the KM2s for three reasons. One, the 305/70R17 MTRs only came with WOL (didn't know that until they arrived) and I don't care for white letters on a Jeep. Two, I have seen how tough the KM2s are on my ZJ. And three, I couldn't pass up $240/ tire installed. What I didn't expect was the added bonus of improved economy.

Of course, none of this matters to anyone but me. Just thought it might be of interest to some.

 

I'm new to this forum, have been researching tires. Wife likes the KM2s, if she's buying...
I am undecided, not to fond of the stock BFGs now that they are wearing down.
Have been considering Goodyear, Cooper, DC, Mickey Thompson, probably come down to price.

 

Kind of off topic but.... I am often in Stevens Point (graduated from UWSP and have a bunch of friends up there) but I was wondering if there is any place around there to wheel?

 

Is this actual measured height, or mfg's spec? From what I have read, the mtrk's are tall for their size, and the km2's are short for their size. Soooo, my first thought was that the 34" mtrk is actually taller than the 35" km2...

 

Wish there was, but the closest is up near Lakewood or Apple Valley near Chetek. It's all private, mostly crop land. That's why we spend our winters in AZ, where the wheeling is pretty good.

 

Yeah thats what I figured there was one logging trail that I found off of river road up by the Du Bay dam. But it wasnt anything to special.. Just a fun place to go play around. Or there are also the roads down in Rapids but those are mostly puddles.

 

No, the 35" KM2 is close to 3/4" taller than the 34" MTR. That is actual measurement. I also had to increase the tire size to get the speedo to match the GPS. The rolling diameter of the 34" MTR is 32.25" to get the speedo to match the GPS. The 35" KM2 has a rolling diameter of 33". Both @ 30 psi. Those are the values I had to use to match the GPS.

FWIW, The specs for the 35" MTR is .8" taller than the 34". I haven't measured a 35" MTR, so don't know what actual is.

I also took a measurement from the floor up to the bottom of the fuel tank skid before and after the tire change. Before it was 13 7/8" and after it is just over 14 1/4" for a gain 3/8" in ground clearance
