I've run Toyo 35's on 15" rims for about 30k miles now. IMO this is the best tire out there that I have seen by far. Though I have not personally run the KM2's, I've followed more built rigs over tons of stuff that they had trouble with.

On the trail I run them anywhere from 8-12 psi, which probably helps them just stick to stuff like crazy. If you look at them, the side lugs are practically as big as the tread lugs, which means that extra contact patch is put to good use. The KM2's are close, but not as beefy on the sidewalls. I have never had a flat in lots of varied terrain, never rolled a bead, etc. I feel like I could even go lower than 8, but I generally don't want to chance it.

On road I run them around 26 psi and they're super quiet. I've even had non-Jeeper passengers comment on how quiet the ride is.

One thing to note: They completely suck in the snow and ice on the road. I feel like this is probably true of any mud tire. Though you say they are "siped" I don't really think the little groove down each lug does as much as the numerous grooves present in AT or winter tires. The compound is soft in the summer, but gets much harder in the cold stuff. I don't know how they would do on a snow run -- I've never tried it -- but I'm guessing not good. I'm thinking my next set will be 37's, and I may actually have them properly siped if I can convince myself it won't lead to chunking, etc.

Anyway good luck with your selection -- though I love the Toyos I don't think you can really go wrong either way.

 

personally ,i think, considering the off-road performance,amount of miles and great on-road ride you get out of them the price is fair

 

I'm interested in this Toyo MT KM2 conversation as I'm thinking of upgrading from 35's to 37's. I currently running KM2's and have been extremely happy with them; until winter came. My driveway is long and is crushed granite so it doesn't retain the suns heat like blacktop and once the snow packs and it ices up it stays that way. The KM2's weren't doing too good. That plus the fact that we were going to Moab for some winter/snow wheeling caused me to get the KM2's siped at Discount Tire. The tire is much much better in the packed snow and icee than it was before.

The machine Discount tire uses puts many more sipes in than I see in pics of the Toyo or any other "siped" MT or AT tire. The Bridgestone Blizzacs on the wifes car are heavily siped and work great. I'm at the point were I don't really consider what they Toyo has as siping except that it's enough to claim it is siped. The sipes don't run across the tire like the Blizzacs but follow the pattern of the lug.

I wonder how the Toyo would do in snow and ice if properly siped. Whatever tire I get next I'll buy the Ideal Tire Siping Tool and do it myself. I think I can do a better, neater, more complete job.

How did the siped KM2's do in Moab? We got into quite a bit of snow on two of the 5 days we were out and I was impressed. There were a fw places where it was very icy such that it was hard to walk on and I felt in complete control in the Jeep. The KM2's might be better to sipe since they don't have the "siping" from the factory that looks like it would get in the way of proper siping.

Either way I'm enjoying the info in this discussion. I just get the nagging feeling that the Toyo is too heavy and too stiff for the weight of a JK. On a 3/4 ton or 1 ton PU I'd definetly get the Toyo. My 3/4 Ford 4x4 diesel goes across the scale at 9500# and the Toyo's would probably be great on it.

 

I've been running KM2's for about a year. I got them because of the great reviews and the much lighter weight when compared to the Toyo's. I've chunked out the rears a bit (heavy foot I'm told) and they're not as good in the snow as I'd like. On Ice I'd rate them as poor. I'm going to try the Toyo's next and see if the weight gain is worth it. WayofLifes comparison of the 2 tires is right on. With you living in BC I'd think that the Yoyo's would be better for your area.

 

I have the KM2's and i really like them, but i will be checking out the Toyo's next time i buy tires. Also i have read that right now the KM2's are on back order for awhile.just something to check into and to think about if time is an issue.

 

hmm, interesting this is opposite of what I've read on here...somewhere in the KM2 winter issues thread people seem to be much happier with the toyos when it comes to winter conditions.

 

Like I said, I can't directly compare with the KM2's in the snow. Compared even to the stock AT's that came on my rig, they are horrendous. I grew up in snowier areas and have a pretty good amount of experience driving in the stuff, so it's not like I'm just gunning it all over the place. I picked up a set of chains for when I need the traction. Not a big deal for me since I probably only drive in snow a few times a year when I go snowboarding...

 

when it comes to snowy/icy roads, NO MT will perform as well as an AT as there are a lot fewer edges to bite with and give you traction. having said that, of all the MT's i have driven on in snowy/icy road, toyo's performed the best.

 

That's good to know. And I imagine with some additional hand siping they could do even better. Stock the KM2' are wose in snow than I thought they would be. Siped they are pretty damn good but not as good as an AT.

I'm still havin a hard time wrapping my head around a 10 ply tire with s 4300# weight rating at 65 psi. Can it get soft enough to do well in sand and give a good ride? I accept that it's a good stout sidewall and that is good and I suppose I can deal with the weight as it's low. Does it wrap around rocks as well as an aired down KM2?

I wish Toyo would come out with a load range C tire with a stout sidewall for lighter vehicles like the JK.

 

I like the KM2 because it comes in 255/80R17.
