    SimpleTire’s view on Cooper Discoverer STT Pro tires

    Cooper designed the Discoverer STT Pro to be used on Jeeps and light trucks as it features alternating shoulder lugs for strengthening traction in mud and other soft surfaces, and the Discoverer STT Pro's mud release dimples force out loose soil and mud to further strengthen grip. Built with inner tread ribs that reduce noise and increase stability, the Discoverer STT Pro is engineered with an Armor Tek3 construction for added durability. The embedded stone and mud ejectors within the tread help this tire to stay clean for great traction, while added sipes help prevent cracking so that the tire has a longer lifespan and making This is a solid mud terrain tire, but if you compare it with the Maxxis Razr MT-772 then you get a warranty of 40,000 miles, increased tread life, and superior traction.

    Vehicles the Cooper Discoverer STT Pro is a good replacement tire for

    Consider the Discoverer STT Pro if you drive a Jeep Wrangler, Toyota Tundra, Ford F-150, Nissan Titan, Jeep Gladiator, Toyota Tacoma, or similar vehicles.

    Worst tire I've ever owned. Cupped after 7k miles, Cooper wouldn't even consider a swap unless I bought a new pair and sent the ones I bought in for evaluation. Horrible tire and horrible customer service by Cooper. STAY AWAY!! Horrible vibration, and yes I rotated my tires as recommended.

    I've been running these on my Toyota tundra since I got it back in 2009 and I gotta say they've never let me down.. Ever! Just like every other MT tire you have to keep them rotated every 5000-10,000 miles if you want them to wear even. This winter we got like 8 inches of snow with ice underneath, people were in ditches wrecking, all along I didn't spin a tire. I recommend these to anyone. My only grip is when I first started buying these you could get them for about 260.00 a tire and that's for 295/70r18 now they are 314.99 a tire. I see Kumho just redesigned their MT tire and they are around the 250 mark anf from what I've seen and read they're pretty good, might have to give them a try next go round! Cooper sst pros are worth the money so don't think I was saying anything bad about them lol, I'm just cheap I guess!

    I've had a set of these for almost 2 years now and there's still plenty of life on it. I drive a Toyota FJ Cruiser with a 3" lift and i decided to make a change from BF Goodrich KO2 LT285/70R17 to Cooper Discoverer STT PRO LT305/70R16. I love the way it looks on the truck, very aggressive looking and perform well on trails. I've taken these tires to trails in Colorado, CA and Arizona and it hasn't failed me once. I've taken this on long road trips from LA to Oregon, through heavy rainstorm and felt completely safe driving up and down the mountains in harsh weather condition. This will be the first set or many, i plan on getting another set when this gives out. Great job Cooper!

    I have these on my 99 1ton Cummins and they handle the torque exceptionally well. They grab mud awesome which is what I need out of them since it's a farm truck/daily driver. I've got 30k miles on them and they're hardly wearing down at all. They do whine a little bit going down the road when you get over 60 but the positives far outweigh the negatives. Couldn't recommend them more.

    Would not recommend these tires had them put on my 2017 alumduty and the handle on them are pretty rough and way too noisy you can't even have a Conversation in the vehicle with out yelling. And the tires are heavy and give bad fuel mileage so all an all I'll never buy them again the price is not worth it. So I don't Know how all these guys are giving these tires good reviews.
