Duratracs vs ko2

Hey guys,

Been busy reading threads but nothing has been too recent about ko2s vs duratracs. It seems the ko2 are the poster child for the forum regarding tires. Ive noticed more 4runners running duratracs around town. I'm mainly interested in stock size . The appealing part of the duratracs is that they appear to come in P metric load. For the ko2 I'm interested in c-range. They weight of the tires are about the same 43-45lbs. I'm curious if anyone has owned both to see which one has the better ride/noise etc. I live in more of a rainy climate with little to no snow every year. I'll spend 10% off road and the rest on road. Thanks for any opinions!

KO2s will wear better then the Duratracs. The Duratracs will also be louder then the KO2. I ran the Duratracs and boy did they get loud after putting some miles on them.

Being that you are only going to do 10% off road I would steer you towards the KO2. Another good option to look at would be the Bridgestone Revo 2.

Moved to the proper sub forum.

awesome thanks for the heads up. I guess what keeps me shying away from the k02 is just the increased weight of the tire. I suppose c range isn't too big of a weight penalty.
 
I'm in the same boat. Ran the DuraTracs (fantastic winter traction) and now it is time to switch. I am thinking KO2s, especially since I just bought a travel trailer. Just need to sell the one unused spare and I'll be set. I'd also advise the KO2s unless snow traction is a consideration. The KO2s will simply not be as good. The DT is 80% as good as my Blizzaks on packed snow and possibly even better on loose snow....they dig in more.
 
I've had my KO2 for going on 4 years now and have had 0 problems in the snow with them.

i thought the KO2s had a good snow rating?
 
The DuraTrac is practically as good as a snow tire, and I am running Blizzaks this winter. The KO2 is quieter and decent in the snow but just compare the sipes. My friend with his KO2s slides/slips more on turns when the snow gets packed and we go up the same roads to go fat biking. It is relative...I think the KO2s are a good choice and better than most ATs in snow but ultimately not as grippy as the DuraTracs on packed snow. I use Blizzaks now in the winter (of course we hardly got any snow near Denver) but my only issue with using the KO2 is that they come in C-rated only in 265-70-17 and not 265-65-17 (E rated here). If I go up a size, my speedometer is off by 3-5 mph and I sometimes get slight tire rub if the snow gets icy and packs up in my fenders.
 
Has anyone tried E-rated KO2s on their 4Runner...especially 4th Gen? Any feedback on the ride and any weight issues?
 
I run Duratracs and have never even once thought they were loud, they can tend to chop up quick if you don't keep up on rotations thought. I rotate every 7-8k miles. Its a tire that's acoustically designed to be quite lol. I have never had any issue in rain, snow or dirt - haven't had them in sand yet but i figure with my sidewall budge on the stock wheels I wont need to air down much. Ive seen the BFG's be a little less needy on rotations and I'll admit i like the newer AT's better than the older ones, which I hated. I do road drive A LOT - these duratracs have been to Chicago twice, STL and Florida....still got plenty of tread.
 
The DuraTracs were relatively quiet till they got too about 11/32. I did not even notice the noise till then. Then they started to hum away as the space between the tread blocks became wider. They annoy me now. I'm try to figure out how to adjust the speedo so I can go up a size and open up my options.

As far as the tires themselves go, they have performed very well. My 4R does not see any tough trails but does see lots of dirts roads, snow, mild trails, sandy trails, etc. I keep my Jeep for the real offroading and the 4R is the daily driver. The DTs have done remarkably well. They grip really well too. However, I am not too happy with how loud they are becoming and I could use more life out of them. I'm not even as concerned about mileage if the darn things could be as about as quiet as they are when new.
 
So I swapped the DuraTracs out at 10/16 and sold them. I put on new KO2s. While the new KO2s are quieter than the worn DTs, i do not think they are as quiet as new DuraTracs. Still, not bad for an aggressive AT and they have done well so far on sand and rocks. On pavement, they behave well in corners. They feel slightly stiffer (both C-rated) than the DuraTracs and I have them at 34 PSI, and will likely drop them to 33/32 soon. At 36, the side most tread seemed just a mm or two off the road. I dropped 2 PSI and it seems like they fully contact the road.

Overall, I am happy with them since I also pull a trailer. The stiffer sidewall probably makes for a better-controlled ride while pulling the trailer. I have about 2,000 miles on them and no rain or major snow but they will see some heavy Springtime snow tomorrow. Hopefully they will last me a while. Even though I am tempted to buy a full size pickup to pull the trailer, I suspect I will keep the 4R for a while.
 
I ran 33" Duratracs on my Tacoma and they were great. I never experienced much noise with them.
 
I had Duratracs on 3 vehicles. They were great, but I did not get great miles. Best all season snow tire out there IMO.
I am fairly certain I am about to put KO2's on even through the last set of KOs that I tried were not that good. I think the D rated KO2s will ride softer than the E rated Duratracs. Yes I had noise with the duratracs halfway through tire wear.

I have mine 33f/30r and they make full contact. At 35psi the edges would not make contact. Chalk test really helped.
 
Like some of you, I love the Duratracs. Like some of you, at about 8mm (or half) of the original tread depth they got louder. I have also run a lot of different tires on a lot of different 4WD vehicles.
Not only is the 4R superior for my driving style and location in the snow it has been by far the best 4WD vehicle I have ever owned. Must be the weight distribution or something.

Now, after about 43k miles, it is time to get something new. Not only are they louder, but even at 32 psi they break traction in the rain at nearly every stop light. Yes, I do drive spirited as they say. and yes, I do have a lead foot. In the beginning though, I had to work to get them to break. Now, not a problem.

I think the type of snow tire that works best for you (this is mainly directed to the OP) has a lot to do with the type of snow you get. All my snow driving is on asphalt and where I live our snow is mostly wet. The BFGs I tried other vehicles would load up so bad they were slicks. Yes, I knew how to spin it out, trust me. But for safety reason you may want to go slow sometimes. Sometimes... Our snow is like silica sometimes and slippery than anything I've ever seen. We rarely get dry snows. I think this matters immensely.

So for me, from my experience, even with only getting about 43k miles on them (cause' they aint cheap so it stings) I might be sticking with the Duratracs. Unless someone can sell me on something that is a Hybrid MT/AT with as many sipes and tread depth and groove width. Oh, and I have a vanity issue. I like aggressive looking tires. Oh, I tow too. Not at max weight anymore and it is a tandem axle. That helps a little.

I would like to think that there is a better tire now than there was 3 years ago. My cousin has a 2015 4R, and last year got the new BFGs. They look cool, aggressive enough, but for me, the tread looks the same as the older models so I am scared. I need something I know and can trust. I would love to try something new that looks good and gets more than 45k miles on it though.

So like the OP, except for his specific comparison request, what is out there that is better than the Duratrac in wet, heavy, slushy, slippery snow and even some ice, (which the Duratracs are amazing on) or clay based mud, that will last longer and look as Bad Arse? Oh, and up by me, the Duratracs are not only on 4Rs. I see them on everything including Jeeps. That should say something too. Location Location Location. It's all about your type of snow..........

I may try these rear PSI specs and see if it gets any better in the rain. At this point I have nothing to lose.
Thanks!
Rob

EDIT! Took some pics after checking psi after picking it up from the dealer. It was at 36psi on all 4 corners.

Like some of you, I love the Duratracs. Like some of you, at about half tread they got louder. Enough to give me a headache sometimes.

I have run a lot of different tires on a lot of different 4WD vehicles. One was a Ram diesel (forgive me) so the weight thing was not an issue LOL. Before the 4R I had a 12' Tundra. After nearly crashing is 4" of snow in a turn, it got Duratracs too.

Not only is the 4R superior for my driving style and location in the snow it is by far the best 4WD vehicle I have ever owned. Must be the weight distribution or something. The Tundra had a cap too. My driveways are so steep that an inch of snow or less will keep any front wheel drive car at the bottom. Even trying to go up backwards (can't believe I fell for that one).

Now, after about 49k miles and still (like I said) about half the tread, it is time. Not only are they louder, but even at 32 psi they break traction in the rain at nearly every stop light. Yes, I do drive spirited as they say. Yes, I do have a lead foot. But in the beginning, I had to work to get them to break. Now, not a problem. Nannies light up all the time and smack my wrist. I can feel some breaking too in the lateral traction department on tight curves at highway speeds. By tight I mean 40 mph max curves (dry). And at highway speeds I mean 50 - 60 mph.

I think (this is mainly directed to the OP) it has a lot to do with the type of snow you get where you live and not so much what I tell you about my tires or driving habits. All my snow driving is on asphalt. I live in the country, in Maryland, but in the northern region and our snow is mostly wet. The BFGs I used to run, man, those tires would load up so bad they were slicks. Yes, I knew how to spin it out, trust me. But for safety reason you may want to go slow sometimes. Sometimes... Our snow is like silica sometimes and slippery than anything I've ever seen. We rarely get dry snows. I think this matters immensely.

So for me, from my experience, even with only getting about 48k miles on them (cause' they aint cheap so it stings) I am sticking with the Duratracs unless someone can sell me on something that is a Hybrid MT/AT with as many sipes and tread depth and groove width.

Oh, and I have a vanity issue. I like aggressive looking tires. I never go on any trails with my trail. Not until it is paid for. I do off road but it is always a controlled situation. Nothing crazy like some guys do.

Oh, I have towed too. At the limit. But both trailers are tandem axle. That helps a little.

I would like to think that there is a better tire now than there was 3 years ago. My cousin has a 2015 4R, and last year got the new BFGs. They look cool, aggressive enough, but for me, the tread looks the same as the older models so I am scared. I need something I know and trust.

I would love to try something that looks good and gets more than 45k miles on it. I have even considered going the other route since I never hard core off-road and going with a Nitto or something with longer tread life. Something more higher snow than off-road rated. Maybe even something with a shorter sidewall and maybe more diameter. I like the 4R wheels but would maybe like a 18" or 19" if possible. I don't mind a +1 if I have too, cause I don't care about the speedo being off. The computer will adjust on that in 2 or 3 tanks of gas. +2 and you might have some issues. I also don't mind lifting a little but I don't want spacers at all.

I have a friend in NM and he swears by the Mich LT/X on everything he has owned. But his snow is mostly dry and never that icy.....too tame for me....

I have had several different tires including the BFG - most recent Nitto Exo. IMO you simply won't find one that does as good on snow (except for dedicated winter tires) as the Duratrac. That said, I am considering KO2s right now due to possible smoother ride and possible less noise. The Duratrac is #1 if a person is willing to deal with the less-mileage/noise after mid-tread. Dang, I have almost talked myself into going back to Duratrac...
 
I have around 2500 miles on the KO2s now, having switched from the DuraTracs. The one place it is not as good as the DuraTracs is slush/snow. I simply do not see how it could be either, given the DuraTracs extra siping and softer compound. Other that that, it is a very solid tire...good on rocks, sand, pavement, and so far- decent in rain. I like the KO2s but will be more cautious in the winter. If the KO2s wear out fast or start to get too loud, I'll go back to the Duratracs and simply sell them at 11/32 tread.
