Cooper STT or BFG KM2s?

After 6 months of looking I had decided on the BFG KM2 and was intending to sipe them because I drive alot on snow and ice and now I saw a few posts about the Cooper STT. Any experience with this tire particularly offroad (I have LTBs now and abuse them) and onroad in snow and ice? How would you compare them to the KM2s?

Bfg km2

Have 12.50 33 15s on an 01 TJ. I have a 4 1/2" Rubicon lift. Getting a fair amount of road hunt with these tires. Have rebuilt front end (tie rod ends etc) and alignment. Do minimal amount of mud bogging. What tire would be a better choice? Thanks for the input....Chuck

If snow and ice is your game with some off road thrown in and a DD to boot, then the Goodyear Duratrac is what you want, it'll do much better than the KM2/STT.

I guess I should have mentioned I need a 35 12.5 15 and they dont make the Duratrac in that size. Otherwise, I agree though I am concerned with the side wall strength of the Duratrac. I wish GY would make the Duratrac with the MTR w/K carcass and the Duratrac tread (in a 35).

Yeah, no 35's for Duratrac, and the 2 belt sidewall isn't weak, it's just not bullet proof. I wouldn't drag the side walls across jagged rocks. If you're wanting bullet proof, Maxxis Bighorns are good tires. the STTs do better in the rain reviews and on side hill traction than the KM2. I've read the Pro-Comp Extreme MT tires are very good all around tires, and aren't noisy on the road due to advanced design and siping. I think Procomps are actually made by Cooper.

STTs hands down, I walk through mud with those. Best 1000 I've ever spent. 25,000 miles later and they are missing only a 1/8th of the original tread. They are nearly silent as well, mostly because they don't cup (as long as you rotate them regularly) I should get 50k out of mine

I am not sure about the KM2's but I have a friend who runs the STT's on his Suburban, and it rips through the mud really well.

I've thought about getting those for my ZJ, in the 31" flavor, but I can't swing the $800 they want for em.

STT hands down. I've run both, and the difference between the two is night and day.

Better sidewalls, lower noise, safer in foul weather, lower cost, etc. Oh, and my STTs were made in USA too.

Do the coopers balance well?

I'm BFG loyal, always have been always will. I just got another set of 33s. Always got real good mileage out of them. DJ

Mine did. I had 33s and they balanced perfectly fine. I assume the 35s would balance fine too. I loved those tires. The performance offroad was fantastic for me. I don't rock crawl. On road they were almost like riding on ATs.

You ran both?

You ran both the KM2 and STT? I was hoping maybe someone had direct experience with both. Alot of people seem to think the Coopers are 2nd class tires and I dont know if I agree with that. I think its just that they dont advertise much and sell under different names more. I feel like the KM2s might be a tougher tire (and could be wrong) but, with no siping, cannot be as good on road. I am particularly concerned with snow and ice. Any comments on how the two compare with snow/ice? I know neither are Blizzaks...

Well here's the deal.. Cooper makes LOTS of tires. ProComp, Mastercraft, American, etc. They are one of the largest tire manufacturers in the world. The fact that a huge majority of their stuff has "Made in USA" stamped on it is just a cherry on top. Personally, I'd pick Cooper over BFG (French) any day of the week.

BFGs are the most over-rated tires on earth. We can trash the KO all day long for it's failures, but you are specifically looking at KM2. The KM2 is horrible in ice and rain. I ended up selling my KM2s to a forum member and the following week they told me they almost rear-ended a car because of those damn tires. Not to mention, MY set of BFGs was loud too. Like, deafening loud. A lot of people talk about the KM2 being a quiet tire. Those people must need new batteries in their hearing aids. To be fair, they were load range "E" which does not belong on a Jeep, but that was all that was offered. This added to the stiffness and sh*tty ride. I basically just hated the tires the whole time I had them which wasn't very long.

The Cooper on the other hand has siping and a better tread arrangement. So it does a much better job as a street tire in my opinion. And it digs hard offroad. It has ArmorTek 3-ply sidewalls, so it trumps the KM2 there as well. I've seen people get outstanding mileage out of the STTs. I just personally think the STT is one of the best all around tires on the market.
