i haven't had a chance to drive the mt/r in snow or ice yet ,,, but i do know the km2's suck in snow - ice

 

MT/R with Kevlar, great on road and off. I can verify the on-road part so far (I just got mine yesterday). I had KM2s prior so can give some feedback comparison shortly .........So far very smooth on the road and not loud. Very similiar to the KM2.

About to get KM2 in load range E want to hear from others does it really hurt performance ride that much as stated below THX

 

I ran yokohama Geolandar MT's on my last 2 TJ's, and absolutely loved them. Awesome on and off-road performance, way quiter than the MT/R's that i had, and great mileage. Has noone else ran that tire? Only thing i'm not sure about is i think they only come in a R15.....

 

While I don't disagree with planman on what was stated in regards to load range E tires, there are two distinct advantages of them. Less sidewall punctures and less tire sway on road. They'll definitely eat some power, but you need to figure out what you really want out of your new tires.

 

I would also like to know the differance between the 2.

The performance is definitely debatable as thinner side walls will wad up more, promote cupping of the contact patch and don't necessarily provide better traction. The right feel for a load range C and a load range E is totally different and you'll tend to see the load range E guys aired down more.

The better argument is definitely weight as load range E tires are heavy, but at the same time I don't see as many punctured sidewalls on things like the Toyo MTs as some of the lighter sidewalls. I also don't see the Toyo MTs getting stuck with any greater frequency than other lighter tires.

 

not sure about the other 2 tires, but have heard alot of complaints on the KM2's. That they are great with road noise and in mud and sand, but have weak sidewalls when rock climbing. I know a few guys who have puctured the side walls on minor climbs. They were not happy. I am running super swampers and so far love them, but haven't had them that long. Only time will tell.

 

I know you didn't mention Nitto Mud Grapplers, But have you considered them?
I just mounted my 37" Mud Grapplers myself onto AEV Pintler beadlocks at home in my shop. I put them on the jeep and took it up the road, fully expecting the ride to be really rough ( I am used to super swampers). I could not believe how smooth the ride was. I don't think that I need to balance them. I have had them up to 65 mph and still smooth as glass.

You may not want to rule them out.
