Description: Cooper Discoverer STT On / Offroad Tires


The Discoverer STT is Cooper's premium high void off-road light truck traction tire designed for drivers who want the utmost in off-road traction. It is offered in a wide range of commercial and large diameter flotation sizes and is designed for use on pickups, SUVs and off-road vehicles.


DEEP BUTTRESS LUGS


The Discoverer STT's aggressive tread design extends far down the sidewall of the tire to enhance its soft surface traction and also provide additional “bite” in rock climbing applications.
RIM FLANGE PROTECTOR


Strategically placed in the lower side wall area, this feature helps protect the wheel and tire from hazards in off-road driving conditions while enhancing appearance.


TAPERED STONE EJECTORS


An integral stone ejector rib extends down from the center lugs to the buttress blocks to help prevent stones and debris from lodging between the tread elements while contributing to the overall soft surface traction.


SUPER TRACTION TREAD


The Discoverer STT's computer designed, non-directional tread employs a combination of features including deep buttress lugs, notched and scalloped shoulder lugs, and a unique center traction zone to create a bold, aggressive tire for tough off-road applications.


ARMOR-TEK3 CARCASS CONSTRUCTION


The heavy duty carcass of the Discoverer STT is constructed of two radial polyester body plies and one angled polyester body ply to deliver 3 plies of protection for superior resistance to impact breaks and bruising.

Pros: Last longer than expected
Cons: None

The only tire I will use now.. I have 37 X 12.5 on 17" Rims and they last such a long time. People are always asking where I got them from and how much they cost.

Pros: How good they work
Cons: price

I have used them on mud, sand and gravel. Great all around tire, I have them (285/75r16) a 3/4ton Suburban with 3" lift. WOW I was impressed with my first outing in the mud, drug both axles and this was with a open rear end. I have since added a locker and it took me to bury the truck down to the frame axles and rear bumper to finally stop it. Took 4 trucks and 18000lbs of winching to get me out. They are a great general mud, trail but are not a bogger. They have gotten me by for now. They are quiet on the road handle daily driving real good.I'll keep buying them until they change them.

Pros: Excellent on gravel and dirt as well as the street
Cons: None

Any tire on any vehicle when driving on ICE you need chains.


CHAINS, hey knuckle heads Chains, do you understand chains.


Some sent me a video of a city bus going down a STEEP paved CITY street and the bus went side ways hittting a city electrical pole breaking it and then moving on down the street.


The driver should have been fired, for not chaining up, and the top people at the bus organization should have been fire IMO for not proper training IF they had not told drivers that THEY must chain up when it is ICEY and going down city streets.


NO tire is Safe on ice with out chains.


Thank you.

Pros: Not sure not unless the complaints are boogus
Cons: Don't know

I live north of Syracuse,NY in the fabled Lake Ontario snow belt. I ran these tires on an 04 Ram 3500 Quad Cab with Cummins engine, and granted it's a heavy truck but these tires are the worst I've ever had for tread life, 13,000 miles and they're nearly slick!



I use my truck to tow and haul heavy payloads, but all well within the trucks legal capacity, and I run the pressure around 74 psi front and rear. The tires were also rotated frequently and they still suck for wear!


UN QUOTE


Could Cooper reply on this one.


I have a one ton GMC, and a couple of times a month I will haul heavy but NOT over limit whats so ever on snow, and gravel.

Pros: ran for over 60,000 miles
Cons: vibrate really bad when worn down

I have a set of 315/75/16 on a 2003 ford f150 and these are the best tires I have ever owned. I have had super swamper tsl, maxxis bighorn, bfg all terrain, and destination MT and these are by far the best. They get insane milage out of them and on top of that will go anywhere you point them. The only complaint is the vibration and noise when they wear down but they still aren't near as bad as my TSL's. I will never own another tire and actually just bought another set. They are a little expensive but defiantly worth it!!!!

Pros: good traction
Cons: prone to flats from sticks



had two flats in two different tires this weekend. driving in the snow no less. both punctures from sticks. not driving crazy, would not buy agian.

UN-Quote from previous poster.


I have used michelin XPS traction tires 235x85 16's before on my one ton GMC 4x crew cab.


I have purchased coopers for the more aggressive tread for use on low snow with chains. The Michelin XPS tractions were great on rock/gravel roads going home, but chains were needed were on snow above four inches.


I have never had over the GMC limit on the truck and average wait hauled is 300 pounds.


So if my new tires get flats on sticks "Hard To Believe" that complaint or the Side wall blows out on my 8 miles of gravel road hauling my trailer or 3 to five hundred pounds in less than ten thousand miles is there a WARRANTY ?


I am not talking about Abusive use whats so ever.


Please reply cooper as your web site has silch on warranty. ?


Thank you


I just purchased

Pros: Decent mud and trail tire
Cons: Wear fast and unevenly, tough to balance, flat prone

For being Cooper's "premium" mud terrain tire I was disappointed. Tires were great first 4000 miles, then they rock chipped to bits and wore very uneven despite having my truck (GMC 2500 HD) aligned twice for no reason. The tire shop had a hard time getting them to balance initially as well. They are decent in snow and mud, but I've ran other tires (MT/R's, BFG's, Duratrac's, Destination M/T's and Bridgestone MT's) that performed way better and held up longer in the field.

Pros:
Cons:

I have used Michelin XPS traction tires 235x85 16's before on my one ton GMC 4x crew cab and the XPS are on my Chevy Dually and wonderful gravel road tire, but again Chains with snow. The XPS have do not have traction up hill on snow that the STT's do.






I have purchased Coopers STT's for the more aggressive tread for use on low snow with OUT using chains. The Michelin XPS tractions were/are great on rock/gravel roads going home, but chains were needed were on snow above four inches going UP mountain gravel roads.


++++++++++++++++++


Okay, my STT's are new, and they rode wonderfully brand new at 55 MPH one a two lane pave road going home, smooth and Quiet for deep treads.


My Question is this There have been some complaints on this forum that seem totally Bogus to me, but there are some about premature severe tread wear using them on Gravel ROCK Roads.


Note to Cooper, I may ride 8 miles of Gravel road, but the roads are in good shape climbing 2500 feet.


I never have over loaded any of my pick ups at any time, my trailers are four wheeled double axels.


I hope this tires get 10,000 and the not what some claimed on here.


If the these reveiws are all by end useers then IMO the majority did not have problems and that alone speaks well of the tires.


When I get 5000 miles on my STT's I will report but that won't be till around June 2011.

Pros: quiet, good in mud/snow
Cons: dig too fast

I really like this tire i have the 33/12.50/16 on an 02 tacoma and they do really well however when in thick mud they tend to dig down too fast. but overall great tire.

Pros: Awesome traction, treadwear is good, look great!
Cons: Takes a lot of weight to balance, a little noisy but tollerable

I've had a set of 285/70/17 on a 2002 F150 for 2 years now. They have 20K miles on them and they look brand new. I rotate twice a year, so I just dont understand why folks complain about the tread life. Seems like Dodge owners complain about every tire. Well, on my truck these tires dont wear at all and traction in every element (except ice) is great. I drive through deeeeep snow all the time with no problemo. Heck, I have to pull other trucks out of the snow banks and ditches all the time, but these idiots have street tires on their rigs. I'm getting a new truck in the spring and I'll put these same tires on the new rig. People complement my wheel/tire looks all the time.

Pros: great looks and truck goes everywhere its pointed
Cons: NONE AT ALL!

excellent tires, highly recommended, performs great in all terrains never had any problems with these tires, ive run both stt and the st for about the last 7 years and i dont think ill ever buy any other tire. and of course no tire performs good on ICE without chains so thats no excuse for underrating these tires. the price is right. im currently runnint the st with about 50k on them and getting the stt again for a more aggressive tire for the sand. amazing performance and recommend to everyone i know thats looking for new tires. i run 285/75/16

Pros: Rugged, Great tracktion, Good Looks, Durable
Cons: Heavy

I drive a 2007 Toyota FJ Cruiser 4x4, and these tires have improved the rugged looks of the vehicle. Snow tracktion is awesome! These tires will dig their way through the snow to get to the ground and get you where you need to go. Mud driving is very good if wet mud, but almost all mud tires suffer a little in the peanut butter type mud. Road handling has actually imprived over my AT's because of the stiffer sidewall, and these tires have a soft rubber compound which lends to better grip on wet,or even slushy roads. I is normal with all tires (IMO) but they have served me well with the deep lugs grabbing onto anything they can to start and stop in bad weather. Buy these tires and you will not be dissapointed. They are pretty quiet (so far) for a mudder, with a pleseant humm as they move.

Pros: great price
Cons: none so far

I have only had the tires for a week so i dont have a whole lot of input on them but so far they are quit on the street and aggressive enough to cut there way through the mud.

Pros:
Cons:

Okay, here is a field report.


I used a 97 Ford 3/4 ton 460, with a 410 rear end. A dump trailer had TOO much gravel loaded !


I should have dumped a third of it.


I climbed a steep gravel Mountain road, and made up the worst part. Barely, and I won't do that again, but If had, had any other SUV, Cooper, Michelin, Good year MT's etc, I would have slipped back sideways off the road.


COOPER STT's at 65 PSI did the impossible.


I now rate them Champ

I now rate them Champion tires that are quiet for what they are, and proof you don't have to have stupid looking big mudder tires on your work rigs.


Thank you Cooper, and that nine mile trip with over loaded dump trailer is the last for me.
