2nd Gen Non-Engine/Transmission Cooper Discoverer S/T-C

[MBFARMS]

Anybody running these tires? What are your thoughts. I have previously been running the AT, they are great tires, but need some extra traction around the farm.

 

[TJany]

i don't have the ST-C, but i am running the ST (don't know if theres a difference or not)

i only have about 6000 miles on them but i love these tires, they clear nice if you can keep them moving. I've been in chisel plowed fields after 2 inches of rain and gotten through it without a problem. I have the 315/75 R16's and they do rub on the control arm if you cut the wheel to hard, i find the truck turns plenty tight without rubbing though. the majority of my miles are highway, the tires are fairly quiet and are yet to show wear... was reading a post earlier about BFG AT's losing chunks of tread... we have a bunch gravel driveways including right at my house and i have yet to experience any problems

a couple other things to remember, the S/t's have 21/32nd of tread depth where as AT's are only 18 (if i remember correctly) and i got my tires mounted and balanced at $164 apeice... so they'll prob save you a good $30 a tire over BFG's

Thanks for the reply's. A Local tire shop has them for $634 tax balanced and out the door. If they wear as good as the AT's I will be well pleased. Right now have 32,000 on the AT's and will probably get another 3-5 out of them before winter. They lasted a lot longer than the stock michelins that were on the truck and perform a lot better around the farm.

Discoverer S/T

I put these on about 1 month ago. Don't know how much, if any, differences between these and the S/T-C's you are asking about. I do know these are rated Mud & Snow. As TJany states, the tread depth is impressive. The pattern is more agressive than a A/T type. My son runs BFG A/T's, and really likes the look of these Discoverer's.



Now the downside. A week and a half ago, I stuck the truck pulling 2 gravity wagons. The mud on the farm road had frozen overnight and had just thawed out. It was very slippery. Wasn't the fault of the tires though. I didn't have enough speed to get to the top because I was talking on the cellphone with the combine and not paying attention. These tires do clean well though as there was mud EVERYWHERE on the truck and the first wagon.



Based on my limited usage, I think they will be good on the highway and around the farm. My $. 02.

I had a set of Mastercraft CT tires in 285/75R16 and they were great around the farm. As near as I can tell, the Mastercrafts are made by Cooper. The tread pattern was very slightly different than the Cooper ST-Cs, but they were great in mud, in the field, etc. They were also very good in deep snow, but weren't worth a darn on snow packed roads. I put 64,000 miles on them before pulling them off a couple of weeks ago, and replacing them with Firestone Steeltex R4S's in 265/75R16, which seem to do better on snow covered roads. Come spring I plan to get another set of the Mastercrafts and put them on my aluminum rims, and will buy 4 steel wheels to put the Firestones on for winter use.



Incidentally, the difference between the ST and ST-C is that the ST-C is designed to be more cut resistant, probably made of a harder compound.

 

[BigEasy]

Terry, you're correct about MasterCraft being owned by Cooper.

 

[ProMac1K]

Yep, the S/T-C's have a harder compound for rougher terrain. They would probably wear better than the S/T's given that fact.

 

[ProMac1K]

Here's a picture of the ST.

The only differences between the Cooper Discoverer S/T's and S/TC's are the S/TC's being a cut proof/chip proof tread design and they are also size limited(meaning they are not available in bigger sizes). They are designed for the guys who spend alot of time off road and rock crawlers. Now,I had run a set of the Cooper Discoverer S/T's on my 98 and got 55,000 miles out of them with regular rotation(I used to rotate them every oil change)and by keeping them at proper air pressures. Some like them,some don't But I had very good luck with them myself... ... ... . Andy

 

[Hammer]

One other thing to note with the "Mastercraft" line,is they are notably much softer and are well known to wear much faster than the regular Cooper line of tires... . Andy

What did you think of them for traction Andy? I see they have them in my size. I am running Firestone Destination MT's right now. They are awesome in snow, I mean great even with the light rear end of the dually. I went down a minimum maintenence road to test them out right after mounting them. Talk about traction. I was going through bumper high snow drifts and axle level snow in 2WD. There were times that I felt I should put it in 4WD, so I did, but I didn't have to. But mud was a different story with my truck. Sunk the truck down to the rear bumper in some CRP grass land this summer while checking some crops. I felt a little hesitiation so I put it in 4wd and went slow. Then I started getting nervous so I tried backing out and I just dug ruts. Shortly after that water started flowing in my ruts and literally surrounded me. I was done for. Overheated the engine a bit, and it took awhile to cool down but thankfully I never harmed that. Probably didn't help the transmission out at all, ended up rebuilding that this fall. :-laf However, the Destination's weren't bad in surface mud. The problem with them is that they don't clean out the mud with wheel speed. The mud fills the tread voids and sticks in there until you go down the road. Snow is a different story since it is either light or dense, but not sticky. Snow cleans out well with these tires. I think, and hope, I can get close to 30k out of these tires on my dually. I'm calculating ~1/32 every 1550 miles. The back ones wear great, with all the weight in the front end. I could get a lot out of the back ones, and by two new ones when the ones on the front wear down. Maybe that's the way to go.

I like the way they bit in the snow,the S/T's,and had very good luck with them as as I have said,I have no bad words about them. I,myself,this time switched to the Firestone Destination M/T's for a different look for show season and can not wait till it snows here to try them out. I stepped up a size to 285's for the larger look and am amazed on how much better it made the ride and handling of the truck. I now have 12,000 miles on my truck since The Mopar Show in Carlisle,PA where I first showed with them on. They have been kept at the manufacturers pressure reccomendations and show little wear so far. Towed my sons wounded 93 Intrepid open a open trailer with them this weekend has was pleasantly suprised how well they towed even.



At any rate,there are shots in my readers rig area of my truck with both sets of tires on and they both rate very high with me. I can not vouch for their ability offroad as my truck is VERY allergic to mud and dirt and you ever see a guy underneath it wiping down the frame at a show,that would be me. . LOL... ..... Andy

 

[Ol'TrailDog]

I'm running Cooper STs this winter and like them a lot. Good aggressive M+S tire and they are not obnoxiously noisy. We also have the Mastercrafts on a couple trucks here (see previous pictures above) and they are a good tire also.



Thumbs up!

I have been running the Cooper Discoverer M+S for about a month now and I can't say enough good things about 'em. Great traction in snow (on a frozen field or a road) and in mud (don't know about axle-deep mud, but there you need pontoons, not tires). Pretty quiet on pavement. They improved my truck's handling noticably. I can't speak to mileage as I haven't had them long enough... but I'm one of those guys who don't care about how many miles a set of tires give me. In my view, they're there to sacrifice themselves for my safety and comfort, that's how-come the lug nuts are so easy to reach.
