So I have 41,000 miles on my stock 13 4Runner tires with about 8/32 on some and 7/32 on the others. I am thinking about replacing them in the April/May time frame. After one of our other members posted about the Toyo RTs I started to look at hybrid cross AT/MTs. I had the Mickey Thompson ATZs (on my Tundra) and liked them a lot, but in rocky terrain the edges did chip (albeit I didn't air down).
What I want to know is who is running Cooper St Maxx tires? What are your thoughts about this tire? Mud, snow, wet, dry, ice, etc? I would say 85 to 90% of my time will be spent on pavement unless I can get out more this next year.
-
I have about 4000 on a set. They ride nice and I like the traction so far. I think I'm getting better mileage than the STTs. I've been to Montana with them and over the pass several times. I was worried they'd be like the the TOYO ATs which I wasn't impressed at all with, but they have a little more aggressive tread and seem to have good traction. I had over 50k on my last set of STTs so I wanted those again but they were on back order and I needed something new for Montana. Discount said I could turn them back in even though I told them I was going to put some miles on them when the STTs come in but I'm thinking about keeping them. They are a tough tire.
-
What are you running them on TMike?
-
I put a set on my 2500HD in October. They were great in the mud and snow of hunting season,but they were brand new so take it for what its worth.
Been great in the rain and are very quiet for as aggressive as they are.
-
I ran Cooper tires for a lot of years. Only one set of these though and they were studded up. I had nothing bad to say about Cooper tires new. For the first half of the tread life they were as good as anything I've ever run. Problem I had was with the second half of tread life. They seem to road harden badly and lose their ability to shed the sharp rocks and grip with the ferocity they did when new. My last year running them I think I had a half dozen flats. When one single weekend I blew three tires I decided that was it. Went to Bridgestone Revo's and have never looked back. Could probably buy Coopers at half life twice for dang near the price of one set of Revos though ;)
-
I have around 7000 on a set and I love them so far. My truck sees a lot of dirt roads as well as pavement, no buyers remorse at all. Was always a Toyo /BFG guy but I see myself buying another set of these when the time comes unless they just turn to crap for some reaso.
-
I run cooper STT's, I like them a lot as they are aggressive off-road, but they don't last very long with my F-350 diesel and doing a lot of heavy hauling and towing. My son has them on an old Toyota and they last twice as long. The ST Maxx's look like they should be a longer lasting tread design. I'm interested in hearing more about them as I have considered going to a less aggressive tire to get more mileage out of them on my F-350.
-
I've ran through a couple sets of the SST's which I had zero complaints about. Still have a set with 70% tread after 5 winters (3 1/2 months). I've went through a couple sets of the STT's also. Impressed with the length the lasted. I've never had a flat with a Cooper Tire. I've had a lot of flats with LS tires, primarily anything Wild Country. My last two sets of tires have been Hercules Trail Digger M/T because of the unbeatable prices I've paid. They've been the best performing tire I've used in the winter on the backroads. I'm needing a new set of summer rubber and I'm going with the ST Maxx. I've been in a couple rigs with them and they handle great in all applications. One set I know of is going on 35K and they are still in good shape. All these tires have been on Toyotas.
-
I had two new STT's blow out once within a short time of each other, I think they were just bad ones, I've probably bought 20 or more of them and that was the only time I had troubles. The rest have been tough till worn out. I would assume that most of the cooper traction tires are of similar construction with the variance being in the traction design?
-
10 ply's with 3 ply side walls, right?
-
I usually buy 235x85x16 STT's which are load range E a 10 ply rating. I don't know what they put in the sidewall, but they are pretty good tires, I put them through hell, going places lesser tires have blown out regularly in past years. The sage and rocks in Utah will test tires like nothing else.
One time about 15 years ago I tried Big O tires, they were good traction and the warranty was excellent, I could have kept getting new tires forever, but I got tired of having to change flats in remote areas. :chuckle:
-
Tires of the big rigs sure seem to go quicker with more flats and that's understandable. Load range E all the way for me these days even on Toyotas. That's one reason I think I had all the flats with the Schwab tires because they were all 6 plys. One tire I've seen do very well and I'd definitely run on my fullsize 3/4 ton are the Toyo M55s. Seem to get as good of mileage as I've seen and preform well while being very durable.
-
The ST Maxx has the Armor Tek3 carcass which I believe is 10 ply. All the St Maxx only come in Load range E. The reviews I have been reading have said on the highway it is a quiet tire. Another thing I like is the stone ejectors. On the Mickey Thompson ATZ I swear I would empty out half the driveway once I got out on the road and up to speed.
-
I had a set on my f150 and really liked them, they were very tough tires, extremely thick sidewalls and they were very heavy. I drive on a lot of rocky roads around Yakima and never got a flat with them. I usually had to run around 55 psi in them because I don't like my tires having very much of a bludge in them. I'd buy them again on my next set.

Mine are on a dodge 2500. 295/70/17

Modern radial tire plys have about zero in common with the ancient bias ply construction.
Bias ply tires needed 6,8,10 ply etc for the load they were rated to carry.
A load range E radial is 10 ply equivalent. That doesn't mean they're 10 ply,that means they'll carry the same load an old 10 ply bias tire will.
I think a lot of you guys would be surprised if you looked at how many plys your tires actually have vs what the tire store told you they have.

True reading more about these tires they only have 3 plys not the 10 I thought before. From my investigation the only difference between load range now is how much psi the tires will handle. The ST Maxx will handle 80 psi making it load range E. Reading on Exposition Portal guys run these tires on Tacomas, 4Runners, Explorers and they run lower psi to compensate.

I'm aware this thread has been dead for a month but for anyone reading it...
I know it's cliché but the Nitto 315/75/16 I've ran are well worth the money. Incredible traction in both the trail and mud grapplers. Worked well for towing and solid load range.
I ran the Cooper ST's for a few years but wasn't impressed with how they held up with offroad time. Sidewalls were lacking in strength I thought.
-
I've ran 2 sets of the original ST's as well as a set of the STT's several years back as well. This new ST Maxx is quite a different tire. I wouldn't compare the two in terms of judging the new Maxx off of the older ST model. :twocents:

I've got the ST Maxx on one of my trucks and it seems a little more at home on a lighter (half-ton) pickup.
-
They have a 3 ply sidewall which is quite rare these days, most tires, even E rated ones only have 2 ply sidewalls. Go down to the side shop and grab ahold of one and you understand real quick why they are such a tough tire.
-
I've had them on my '11 F150 ecoboost crew 4wd for 60,000mi. They have never flatted and I pound them chukar hunting, flatted stockers 4 times prior to replacing with the Maxx's. They've gotten slightly noisier with age but it's still more than acceptable. Not the greatest wet pavement or ice tire because they don't have a ton of siping not that it's actually ever been an issue, just the truth. I will run on my next truck too but will likely have the center lugs lightly siped to better the traction.
-
I ran ST Maxx on my Duramax (285 x16) and got 55K out of them and I used them hard. Always ran Coopers til one time tried Toyo MT- crappiest tire I ever had - got 22-24K and gone.... Right now I am waiting for the dealer installed tires on my Ram to be bad then going back to Cooper ST max's again... Normally put 40K+ per year on truck so get new tires every 18 months or so...
-
I'm ordering a set of ST Maxx's in 295/70r18, hope to have them on Friday. First time I have gone with cooper, time will tell and I'll try to remember to give a report in awhile.
Hope the fit ok on my stock 13' f-350.....

I've had the stt and now have the st maxx they seem to be a great tire. They are tested daily in the woods!
-
I ran them on my Duramax and they were good tires, they just didn't last as long as I expected. I had 10 ply 285s on it and I got about 35000 mile out of them with regular rotations. That was a couple years ago, so maybe the quality has improved. I loved the Cooper AT3's, they were a great, long lasting tire.
My worst set has to be the Mickey Thompson ATZ's I am currently running. I have taken them to 3 different shops to have them balanced, and no one can do it. I like the fact that they are not loud on the road and get decent traction, but at 45mph I feel like Im on a washboard. When they wear out I am going back to the Coopers.
-
In general Cooper is a pretty good tire company. Most all of their tires are made here in the USA. They also make a lot of Private lable tires for larger tire dealers. I know that they have made some of the tires for Les Schwab in the past, as well as no name lables for other franchies.
-
Cooper Tires are the only tires at LS that I would consider running anymore.

Waiting to hear your thoughts.
Thanks for all the other reply too!

Had the tires installed this morning (after a long wait due to nation wide back order, found the tires in Idaho finally).
They fit great! Had the truck in 4 wheel drive today at work in some mud and they performed very well. However, I had to make a run over to Seattle and the tires performance on the highway was not very good, they rolled very badly and drove like I had 37" tires on 15" rims!! It was much like driving a boat when quick input was given at high speeds. I have driven lifted trucks with much larger tires my whole life and have not had such bad handling. So on this note I am not very pleased with the tires, but it is not to the point where I am going to go on record as saying I would not recommend them, as the road manners at high speeds were not so bad I won't get used to it. But they are bad enough I won't be excited about my wife taking the truck on the free way, for fear she won't be able to handle the truck in a quick reaction scenario.
I am sure these tires would do much better with 20" rims in this size 295/70, which most guys run. I have 18's.
Anyway, I am going to check the pressure in them tomorrow and I will check back in a few months with a more detailed report!
Thanks,

We install a lot of ST Maxx on crummies. Those guys are hard on tires. We usually pull them off around 40,000 miles. Very few punctures considering 90% use on freshly graded logging roads.
-
Thought I would do one more check in on these.
The tires are great! The bad road manners were due to low inflation, the guys who mounted them only had them in the low 40's. Once they were up to good pressure they drive great and hook up in the snow and gumbo mud very well. I drive my truck daily on gravel and in mud, highly recommended!!

Good to get some opinions here. I'm presently debating between the STT and the ST Maxx in a 285/75 16 for an 89 F250 ext cab. On one hand the STT has great traction, but I'm wondering about highway use and longevity. I've heard they're pretty decent for a traction tire. The Maxx seems like it might be better on highway and snow and ice while still being good enough in the woods....

IMO for a mostly over the road vehicle even a 4x4 you much better off getting an AT and purchasing good link chains. youll get better on road handling, wear and puncture protection... the down side is less off road traction... BUT if you own 4 chains that makes up for the less traction for the 10% of the time you need it. :twocents:
