Dean Mud Terrian SXTs 285/75/16

After running these tires for three months and 4000 miles on my LJ it's time for a review. The Tires in question are Dean Mud Terrrians SXTs, made by Copper. The tires are made in the Findlay, Oh plant on the same carcass as the Copper ST. Originally I was looking at the ST or at another set of ******** Cepek FCIIs like I run on my Ram (great tires by the way). Since the Jeep is my daily driver and weekend woods runner, I was looking for a tire with good road manners, long tread life, and still be able to handle all the winter snow & ice, PA mud and the forest roads and trails the Jeep would be seeing. A couple of buddies of mine suggested the Deans to me after switching to them on thier snow plowing, oil field and logging trucks.

Here's a shot of the Deans mounted. I choose 285/75/16s mounted on a set of ProComp 7089 16x8 rims with 4.5" BS. They didn't need much weight to balance and seemed pretty round. I paid $143.00 per tire mounted and balanced, about 60 dollars less per tire than the ST and FCIIs I was looking at.

And one of the tread.

So far these tires have pulled the Jeep down miles of highway and interstate, followed a certian black Tundra through the forest roads of Rapidan WMA in VA, traversed hundreds of miles of PA forest roads, churned some mud at my buddies old gravel quarry, and weaved through the hemlocks, hardwoods and mud tubs in our part of the world. The are surprisingly quite, more so than the Cooper ST that Jim runs on his Tundra. There's just enough hum to let people know your coming but that's better than any stereo system to my ears. I found that my ride has improved over the other tires I was running even though the Deans are load rated D and my old tires were C rated. The tread handles rain extremely well, when we were caught in a huge downpour there was a couple of inches of water running down the streets of town and never a hint of hydroplaning to be found. They also churn mud pretty darn well also, both in sloppy black mud and in the clay. It didn't take much wheel speed to clean them out and they never packed. Much better in the mud than my Ram's FCIIs and worlds better than the BFG ATs I use to run. In VA they handled the looses shale and rocks of the road we were on without complaint and never once seemed to be looking for traction. They handle nicely on the blacktop and ride smoothly. The only downside so far is that they like to pick up rocks and fling them back at you. and they're not small ones either more like #2 limestone sized. Kerpang! Right now I'm running them at 28 lbs of presure and have a nice contact patch and good even wear. I ran them at 18 lbs in the mud pit and on a couple of backwoods trail and that seemed to be a good pressure for more serious work. Now all we need is some snow and ice to see if these Deans are up to that, though I've been told they work great in the white stuff.

Hers' a final shot of the Deans pulling the Jeep down a forest road north of Kane, Pa during a good thunderstorm.

I really like these tires and if they perform in the winter like I've been told I'll probabley mount a set on the Ram when it's time for new meats.

That's exactly the same problem with the ST's! The BFG's picked up little tiny gravelly bits and threw them all over the wheelwell, making irritating ticking sounds; the ST's pick up much larger rocks and don't throw them until you're really rolling...aaaggghhh! Stone chips on my pretty truck!

For anyone else, what Haggis speaks is true, the Deans seem to be a quite affordable and viable BFG AT alternative.

Les Schwabbe sells those in 33x9.50/15 and I'm really leaning towards them as my next tire. Thanks for the review.

Good write up...........

I tried searching for these around the Scram Diego area.....and could not find them!


I wonder why?

I'm gong to need new tires within the next 20K miles or so.....or sooner if I decide to do the Rubicon!.....LOL....ya right!........so time to start lookin'...........!

I'm leaning toward the Cooper SST's...............!

Agreed 100%.

I really really like mine. and for about $250 less for a set installed instead of the Toyo M/T that I had for about two days, I can say they also give a much better ride.

In fact, I will be getting these when I have to buy tires again.

Interesting that your Deans are less expensive. Out here in the West Deans are readily available from the Les Schwab chain (where I buy most of my tires) but would have cost me much more per tire than the relatively inexpensive price I paid for for my Cooper STs (255/85) from an independent tire shop.

I had a set of SXTs in 255/85 on my LJ a couple years ago, nothing too good or bad to report. I did chew them up a bit spinning them slowly w/lockers engaged on some loose rocks trying to get going on a hillside (not the chip resistant version).

Sweet, who else sells them? Their site seemed to have been hacked and I get a malicious site warning.

Assuming it's: http://www.deantires.com

Always interested in other-than-BFG options in 33x9.50/10.50 sizes on 15" rims. Cooper only lists tires in 33x12.50x15 and so I am wondering if these share a mold with the ST that maybe the Dean is actually a 33x12.50. But if it's a 33x10.50, I'll be looking into them in a couple of year I think!

Your Dean tires link took me to Cooper Tires but this bookmark I had still worked and took me to Dean

http://www.deantires.com/us/en/default.asp

I don't see a 33x9.5R15 or 33x10.50R15 listed for either the Cooper ST or Dean SXT.

I was looking at the Cooper ST ever since Jim got that set on his Tundra. I was really impressed with the way they worked on his truck. When I went to price them around here size 285/75/16 STs were ranging from $195 to $210 at the local shops. We don't have any chain tire stores in the area and I'd rather buy local and keep the money here then order online if I can find want I want. Those buddies of mine were shifting over from the Cooper STTs to the Deans on their work trucks because the STTs were getting ridiculously expensive around $260 a piece and pointed me towards the Deans. I bought mine from the local tire place we've been dealing with for years. I checked on 255/85/16s when I was trying to decide what size to mount, but the STs were around $220 apiece around here and had to be special ordered.

Update: Snow Review

Here's an update for this tire review now that we've had snow for the last month or so.

I've now got around 8500 miles on the Deans. They're still doing quite well, ride is good, wear is even, and are still holding to my earlier comments on they're preformance. For a modified all terrian tread, they handle the late fall/early winter mud quite well, tossing mud nicely while not seeming to search for traction. We've had quite abit of snow and the Deans have shown they're positive and negative traits.

The Bad; icy conditions show that abit more siping would be nice. Don't get me wrong, they're O.K. on ice, but not as good as my FC IIs. They tend to want to wander in the prevailing track on the road surface. The Good; on snow packed roads or in the woods running deep snow they're great. They pull nice and clean themselves easily. I ran up onto the clan's hunting grounds when there was 16" on the ground and didn't have a problem. The tires pulled straight and true and didn't need any additional velocity to clean themselves of packed snow. And if you saw the steepness of the road up to the cabin you'd know how much of a challenge that could be. My Dad's wouldn't even try it with his Titan and the Discover ATRs that are on his truck.

We've run some rocky trails in VA and WV and don't have any signs of chunking, but since rocks are not the main fare that this LJ sees, take that as you like. I'm guessing I'm going to get around 45,000 miles out of these the way they're wearing if the tire's treadware continues on par with current preformance.

Hope that adds abit more to this review if there's anyone still checking these meats and this thread out. I'm pretty happy with them so far and depending on what the actual wear in the end is they stand a good chance of ending up on the Jeep again.

Further Update...

Those Deans keep on rolling with now around 18,000 miles on them. As reported before, they are preforming well and have shown themselves to be a good mud tire for their all terrian background. On our PA Ridgerunner run last week they handled the coal mine sites clay, shale, gluppy muck and tailings hill climbs without any drama or a single wheel spin. Snow traction is good, but still not as good as the DCIIs. At the current rate of wear I should see at least 45,000 miles of wear out of them and will probably break 50,000 miles. Tires are being rotated every 4500 miles and the wear is even across the tread.

I'm now running a set on my Tundra and have experienced the same results other than they do growl louder on the blacktop probably because of the extra weight of the truck over the Jeep. While on our UP trip they handled the sand covered roads of the UP's roads very well. We'll see how they do on the beach next week when we head down to the Core Banks of NC.

I was looking at some Dean SXTs on a truck at a stop light the other day... They appeared to not have lots more void than the DCII. 'A little' more void in the center of the tread, but the outer lugs appear to be about the same void ratio. And Dean SXTs have less void in he center than Cooper ST... do you agree with those generalizations?

Well I rolled at an old DCII out in the shed next to the Tundra's Deans to compare. The Deans have more void in the tread across the center surface of the tire and about the same on the outer lugs. As far as the Sts, i'd say they have very close to the same void across the whole tire, it's just arranged different. Where the Deans are staggered like a lightning bolt, the STs are more horseshoed in arrangement though I think there is more void in the center rib(?) of the STs the way the tread is made. I know that on my Tundra and Jim's with the STs the noise level is about the same from tire hum so I would conjecture that the void should be similar also, right?

Agreed.

I prefer the center void area of the Cooper ST and think it may help with slightly better evacuation of wet stuff.

Yes, I think noise is generally related to void. With a few very modern whiz-bang exceptions, I agree that void contributes to noise and void helps with traction. Got tread noise, Got traction. I like the sound of that :)

I have run the Dean SXT's in 255/85/16 for almost 5 years now. They will need replacing this fall. After less than a year the side walls started cracking. Les Shwab wouldn't do anything about it so I was stuck. In all honesty I will be glad to be rid of them. They have a really hard rubber compound that is horrible in snow and ice. They have cupped really bad and in the last few months have been impossible to keep balanced. I think one of them has started throwing a belt. I'll dig further into that last problem this weekend and replace them now if that is the case. It's hard to think about 5 new tires $$$.
