Just looking for some opinions on these tires. There is info everywhere on these two tires but more input from different sources is always nice to have. The Jeep is a 06 Rubi. Not sure what tire size I'm gonna go with yet, but any info on either or tire no matter what size you run would be great. Even if you just have an opinion on one or both of these tires and don't run them yourself fire away. It be great to hear from as many people as possible..

Thanks

Edit: Just a little more info. For what it's worth This TJ is going be my D.D and wheeled only once or twice a month


PS: http://www.offroaders.com/tech/AT-MT-Tires/ has become more addicting than porn in the last few weeks :cheesy:

Those are two of my top 3 favorite tires, the other one I'll add to the mix is the MT/R Kevlar.

Either way you go, you'll love any of them. I don't know much about the STT other than is a rebranded Toyo Open Country MT, the Toyo being the more expensive of the two.

I will say however the KM2s and Kevlars both have excellent wear characteristics compared to all the other MTs, Kevlars have better sidewalls, and are less prone to slipping sideways. The Kevlars also are slightly quieter on the road since they have that stripe where the tread is mostly filled.

That said I love all 3 of these tires, I used to want the KM2s no doubt, but since the Kevlars have become more available and in more sizes thats what I'm going with,

It was explained to me like this:

Goodyear and BFG have a rivalry,

First there was the AT KO, then the MT or KM1, then GY came out with the Wrangler MTRs (Rubicon tires) then BFG came back with KM2s now GY is back with Kevlars.

Now realize this isn't exact since there were the BFG Krawlers (KX) and the MTRs both of which came in Red Label or Sticky variety for sponsored race teams only but that's not very useful to this since we're (at least I'm) not sponsored.


So another option is wait for BFGs next beast tire.

I've had both and really liked them for different reasons. The Coopers do very well in the snow/ice, probably because of the siping. They are great on the rocks, but chunk easily...also probably because of the siping.

The KM2 are just amazing in the rocks, but I have yet to run them in the snow/ice...I sort of expect them to perform like my old GY MTRs. Which wasn't that great.

On road the KM2 seem a bit noisier, but both aren't that bad for a mud tire.

I really hate mud, so no comments there.

The coopers would be my choice for a daily driver, but it just depends on how you use your jeep.

The Kevlar's are an interesting looking tire.. Unique in there own way. Tread pattern wise that is.. Right now I'm leaning towards the STT's but that is changing by the hour. Don't be shy, More opinions are welcome

the coopers do wear nicely, my stepdad's heep had them. they don't do that bad in the mud, but couldn't keep up with my 50k mile mud grapplers so if your playing mud you might rethink....and yea my heep with the grapplers is a DD. :lildevil:

I've had the KM2's for two seasons now and really like them. Great in the rocks, I'm always getting commonts on how well they grip. On road I found them quieter than the BFG ATs that I had on when the jeep was new. Haven't tried the STTs or MTRs..

before I decided either the KM2 or STT was were I wanted to go. The Nitto's were what I wanted and still would love to have. But at the same point I realized or felt and tell me if I'm wrong, That the Nitto just wasn't a good choice for the amount of time I would be on the road. Also I wasn't to keen on that wide of a tire.. Seem like a turn the radio to full blast tire?

Jimmy B, What size you running ? Do they rub for you at full lock?

i'm running 33x11.50x16's....and no they don't make that exact size any more. i'm running spacers because i'm on a BB and they don't rub at all. as for the amount of time your on the road, when i drive mine to work i run 40ish miles one way each day. they do get louder as they wear, but it's surprising how well they wear and honestly i think my stock tires were worse with wear and noise. they balance well so they run smoothly for a mud tire, if you were closer i'd run you around so you could see lol.

I bought my jeep about a year and a half ago with 35" coopers on them and my brother has a set of 33" km2's on his tj. We always wheel together and its amazing to see how much of a difference a tire alone will make. I think the km2's have way better traction on the rocks and on muddy hills this may be because of the difference in rubber compounds. As said above the coopers tend to chunk easily especially on the rocks. I dd my jeep and believe that the coopers would outlast the km2's as far as street life goes but when the time comes I have no plans to look into the coopers. for what I use my jeep for I think there are way better tires that fit the application. I have herd a lot of good things about the mt/r's and seen them perform very well on the trails.

Been a little off put by some of the STT reviews. Even with the weird ass tread pattern, The MTR Kevlars have gained my attention big time..

Here's my .02.....I hated the GY MTR Kevlars when they came out, even though I was a huge fan of the old MTRs for how I wheel and use my Rubi as a DD. I was set on some KM2s. The KM2s are smooth on the road work great off road....but as it got closer to tire buying time the GY Kevlars started growing on me and it seemed like every truck and Jeep had KM2s on it I decided to go with the Kevlars. I love them. On road they seem a hair louder then the KM2s but that might just be the difference between my TJ Rubi and DAA's LJ Rubi. They roll smooth and look new even after a few trips. In the little snow I had them in last season just after I got them and the rain, I feel they grip on road much better then the old MTRs. Off road, they seem to grip the rocks better as well. I'm very happy with my choice, but I'm sure the KM2s would have been great too.

I don't have too much experience with the SSTs so I won't comment but I feel that you couldn't go wrong with the KM2s, SSTs, or even the GY Kevlar.....I know the tread is weird....but don't totally discount the GYs.....


Good luck with your decision.....and enjoy your new meats whatever you may choose. :D

Friends had STT on their Ram. They swapped them for Toyo's due to problems cutting sidewalls. They didn't crawl the truck, but somehow managed to get several cuts in the sidewalls on a few occasions. Fust food for thought. They may be similar to the toyos, but the STT's sidewalls are not as durable, that for sure.

Jonathan, mushroomax has the new MTR's on his full sized tahoe and they are holding up pretty good on a heavier rig than our jeeps. I have mostly always ran MTR's, they have always done me good.

Out of the two you started this tread with, I would go with the STT's due to daily driver and snow. If you don't mind siping your own tires, get the KM2's.


Glad you liked my quote about "hummers"...LOL!!

Yeah, Hummers are good.. In 3 days I will be living in Florida. Won't see any snow in person till the 2011-12 winter. I'm likely heading for the KM2's.. I can always have them sipped as it is not one of my talents yet

I was looking at the KM2 and the MTR Kevlars and then ended up with Mickey Thompson MTZ tires. Didn't go with the KM2 because of all the comments about weak sidewalls that I saw and the lack of siping. Didn't go with Kevlar's due to the diretional treat pattern. After getting the MTZ's, I think they're awesome! After a couple wheeling trips, no issues with chunking or sidewall damage and they are much quieter than my old MTR's (stock tires, not Kevlar).

I spent many hours trying to decide which tires to get. I went with the stt's for their on-road performance since I dd mine. After about 10,000 miles or so and a jamboree trip to windrock I have nothing but good things to say about them. Awesome in the winter and flawless off-road. As a side note-cooper makes/owns Mickey Thompson and Pro Comp tires. I saw more baja mtz's at the jambo than anything else, or at least it seemed like it. Good luck and happy trails.
