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: Great looks! Excellent performance
Cons: more siping would be better for icy traction

Purchased (5)LT285/75R16 SST's about 1000 miles ago. Installed on an 08 FJC. Loved the look, feel and performance since mile 1. On the street, I air up to 50-ish psi to help with the mpg factor; on the trail, down to 18-20psi and these things grip like mad. Could probably go down to 12-15 psi to get the most out of the rubber, but I lack bead locks (don't think you'd need it with this stiff a tire) In the mud, on the trail, I have ZERO complaints. Even the loosest, nasty wet deep sand was no match. Quite impressed with the performance! On road there is a bit of noise (to be expected with an MT type tire), but way less than the Goodyear MTR's I used to run. They corner well, ride smooth and the "rock ejector" feature really works! No click click click as you are driving down the road!


I would definitely buy these again.

Pros: Great tire for price
Cons: So far so good

These tires are on my 2003 FX4 f-150. They are 285's. They are very aggressive tires that work well on all surfaces that i have been on thus far. Overall a great tire. I have seen no tread wear and ive already put ten thousand miles on these tires. All around GREAT!!!

Pros: Quiet, for such a rough tire
Cons:

Have got a set of 35 12.50 17 on an 02 f150 and like them alot. They do great in the mud and handle nice on the road. I have about 40,000 on them and they are ready to be changed out. Not to bad for an agressive tire. Going next week to get another set.

Pros: Queit, good in snow, wet roads, mud
Cons: Horrible in cold weather on slick roads

My friends all have these tires and when I finally wore out my pro comp xtreme a/t's they couldnt get me another set for 8weeks so I threw these on. They were $50 more/tire but my buddies raved about them. They are good in most conditions and just as quiet on the highway but the front end of my truck slides when I take corners with a skiff of snow on the road, where my pro comps didnt. And I am reasonable I know ice nothing grips but I think most ppl mean slick roads. Compared to the pro comps they suck in cold (under -25) but that is my only complaint. Just gotta find out how long they last.

Pros: I hope they are a great tire
Cons: If not oh well lol

I have taken the day off Monday and Tuesday. Monday I will put my lift on new ball joints and new pol bushings. Tuesday I go down to the tire shop and get my new stts mounted and balanced and an new alignment. With a fresh new front end these tires should wear and work perfect

Pros: good looking tire and quite
Cons: mileage

I got these tires after lifting my 2008 Z71 4x4 and i did not have any troubles with the tires. The only beef I have with them is that they lasted me 8 months and about 15,000 miles. Past that they were a good tire..I would not buy again. I got a set of NITTO MUB GRAP. and i love them.

Pros: Great in mud,snow,gravel roads, and wet/dry conditions
Cons: not best on ice(but what is)

27,000 miles and still half tread on a 04' Frontier! Last a long time compared to other mud tires, not the best on icy roads, but you cant expect that out of a mud tire, i live in wisconsin so i experience every condition possible, they work great!!!

Pros: Long tread life, stable at all speeds, good off road traction.
Cons: None

I have these tires on a 2006 F250, very stable at all speeds, on and off road. Snow or mud, I have no complaints. I put 25000 miles on them and never rotated them until 25K when they started to chop but soon smoothed out.

Pros: Good for any every day driver/ weekend wheeler
Cons: Full Size Trucks

You people dont know shit about the tire until you buy it. So quit making up shit to make other tires look better. Ill admit that there are some better tires. But i dont believe that there is a better tire at this price. NO TIRE will candle good on ICE unless you have studs. If you want a different tire then buy it. I have a set of 32x11.50s on my dodge dakota and about 35,000 miles with well more than 50% tread still on them. Dont judge the tire until you buy it.

Pros: good all-around mans truck tire
Cons: not all that amazing in serious mud, sand, or wet pavement

have a 98 dodge ram 1500 4x4, with a 5.9lt v8. i bought the truck about 3000 miles ago when i moved to NC, its got the 285/75-16's(supposedly 33x11.5). since then they have worn/chipped considerably; mostly because my own fault, becoming familiar with more miles in trails/open woods that will will for the most part fit a full sized truck than the roads going to and from work (military) like i should have.


trails, creeks, steep hills made of grass, clay, mud and rocks that i thought i would have a hard time with but went up with surprising ease. sand pits, mud, water holes, and the occasional rafting trip that more or less had to with the flotation abilities of my truck and not of the tires. yeah, bad choice but it didn't look that deep at the time, until i saw a solid wave of water ramp 10 feet off my windshield in slow motion and my truck began to shudder from the water filling up in the intake and the exhaust bubbling out from under water.


but believe it or not, after my truck sunk to the bottom, those tires caught something and slowly (limited to the low speed of engine) dragged it safe onto semi dry land.. both times.. from different areas.. that should mean something, right?


saying that, like all tires are horrible on ice, these tires are scary bad in dry deep NC sand. 4wd wasn't working well because of the water in diffs from last canoeing experience mentioned above. ultimately 20mins later still in 2wd, i got out, but from now on, i avoid dry sand unless i have a backup truck with a long tow strap and hit the sand with speed, then its no problem. especially if the tires are deflated, but as with most of us with daily drivers, its not fun to deflate your tires, bettering the risk of a bead blow out, then driving to a gas station to re-inflate your tires meanwhile your tires wear faster than normal due to the lower pressure. impractical, but hey, what can the average joe do about that. loose sand stinks like driving on ice.


in mud:
these tires i must admit are less than amazing. they load up in the thick mud or other sticky devilish stuff, but with most "mud" tires, apply speed, and they will "self clean". no awesome mud slinging, bog broiling mud tires. but then again that's why they have "super swampers" and "boggers" and "ultra mega mud tires". they are there for the die hard mudders that have money to spend on their super soft compound tires built FOR mudding, not everyday street use on the daily commute. like me, or the average joe, who lives paycheck to paycheck. i have yet to see a tire that does it all. heck, i just happened to buy the truck with these stinkin' tires on it that turned out to be an exceptionally above average, average working mans truck tire. at the same time i want to say a disclaimer that these super duper miracle mud tires that people get all worked up about are the best at what they do (churning mud while moving steel), and eventually i plan on getting a set of interco ssr's. that is when and if i get a lot of money. until then i will stick with the ones I've got, which work insanely better than stock tires, probably even my truck with the coopers in 2wd would work the same if not better than stock tires in 4wd, under some mud situations that is.


Now on to the wet weather handling. recently I've had a lot of miserable in the forecast, and here in NC it only seems to pour while I'm driving to and from work. when i said pour, i meant that if my windshield wipers worked about 3x faster than max, i could see out my windshield. regardless, these tires could either use more weight in the bed or a weaker engine (my 98 5.9lt v8 with a K&N intake and Hypertech programmer is pretty stout in torque department), or they could just be to worn to have normal wet traction. im not sure which one, it could just be these tires stink in wet weather, but one things for sure, its fun to drive when its wet out. i can punch the gas going 30mph and posi will kick in when the rear tires are lost somewhere in a high speed heaven, and the rear end drifts off to somewhere where cops love to pull you over. because of this in wet weather i take low speed turns slower to the point of it being probably more dangerous due to road rage than it is of sliding out of control and hitting, no.. ramming something with my dodge. just like no tire is perfect on ice or in deep sand and perfect in another area. id assume that it is normal for this tire to be less than amazing on very wet pavement. but it is more than acceptable in terms of wet performance with a "mud" tire. just like there is no such thing as an "all terrain" tire, sorry, "un-named tire brands", but that was a great sales pitch until people who actually value the usefulness of their trucks realized that they would be useless in the everyday drivers schedule except to look pretty.


there is no such thing, and wont be until cars fly, as a tire that does it all great. PERIOD. anyone care to prove that wrong please feel free to make your argument and let the other people post on that, but this is not what this post is about. saying that no tire can do it all, i would have to say that these old coopers would come pretty close to being a do it all tire for the average joe. but then again it all boils down to how much money you can spend in rubber towards what you want your truck to do realistically. so look around and find a good deal or just spend alot of money and buy some new tires. everybody is different, so find out for yourself. i hope this helps everyone.
