    I wanted to write a quick experience about the Cooper STT Pros thus far. Granted, I have only had these tires for just over 90 days, I felt I should give an update on my personal thoughts as I have suggested these tires numerous times, and several have followed suit!

    Unfortunately, (or fortunately- depending how you look at it) we are in summer so I was unable to give these an in-depth review in our snow.

    A little background on Cooper:
    Cooper Tire & Rubber Company has a manufacturing history spanning just over a century and is currently the fifth largest tire company in North America. Cooper offers a handful of different SUV and light truck tires from very mild to all-terrain to mud-terrain. Each tire in the lineup is meant to provide competent highway handling but serve a second need in the dirt, with increasing levels of tread aggressiveness.

    Features and Benefits:
    The Cooper Discoverer STT Pro is summed up to be the biggest, baddest and most extreme tire that Cooper has ever made. Get ready to pulverize the streets and hammer through the mud with Cooper's newest offroad offering. This mud terrain tire is constructed with a 3-2 inner tread pattern and large depth side bitters to enhance traction, handling and steering response. The Discoverer STT Pro is equipped with 3-ply Armor-Tek 3 carcass construction for maximum strength and durability in any off road terrain. Coming through with great refinement, this tire also delivers on road with a quiet tread design, and solid road manners; Cooper's Discoverer STT Pro will truly show everyone what your truck or Jeep is made of.
    Source
    • Armor-Tek 3 carcass construction: stronger and tougher composition to provide more protection in extreme off road conditions.
    • M+S rated: Durable in snowy and muddy conditions with enhanced traction.
    • Flex groove: maintains flexibility of the STT PRO, for a smoother ride.
    • 3-2 inner tread ribs: delivers excellent handling, traction and even treadwear.
    • Large depth side bitters: improves grip and traction on loose surfaces.
    • Staggered tread pitch: delivers a smooth and quiet ride, despite the large, biting lugs.

    upload_2016-7-23_19-56-45.jpg

    Dry Traction: The grip is great! I am running the 35" (305/70/18) STT Pro's and their ability to stay in line with minimal correction at the wheel is definitely top notch! With as bad of roads as we have in CO, the wander was minimal in comparison to previous tires I have ran in a 35" (or close to) size.

    upload_2016-7-23_19-57-14.jpg

    Wet Traction: In CO, we sustain a decent amount of rain during our early/mid summer months. Actually, flooding is normal at some points. I had the opportunity to take them down some flooded roads (safe to travel) and multiple wet streets. On my previous set of tires (Nitto Terra Grappler G2's; 295/70/18) my tires would hydroplane in small, unavoidable flood spots leaving my heart bouncing out of my chest at times. I have yet to experience this with the STT Pro's!

    upload_2016-7-23_19-57-42.jpg
    Road Noise: I have several personal friends who run the STT Pro's in this size and prior to obtaining these tires, it was a large concern of mine due to fearing they would be as noisy as the Toyo M/T Open Country's I ran on my last truck. Despite having personal friends who stated very similar, I needed to find out myself.

    To much of my surprise, these tires are not close to, or even half as noisy as the Toyo's!
    These tires are surprisingly quiet for such an aggressive tire. These are the quietest M/T on the market. There is some "road noise", but not as loud as you would think. They are louder than the KO2's, but not much.

    In Closing, I would easily run these tires again! I have recommended them to multiple users on this forum, and other social media sites that took my word and share similar thoughts on this tire. So, if you're on the edge of purchasing these- Just do ETTTTTT!

    Good review Sean. If I was to ever drive a MT tire on the road, these would be at the top of my list.

    How would you compare this tire with Nitto Trail Grappler?

    Speaking of rock crawling, I have had a few buddies run these Cooper STT tires in some of the roughest trails and they did very well for a tire you can drive every day. (Not everyone tows their junk)

    Most of the local 4 wheelers I met/saw in Anchorage were running with the Discoverer STT's. No doubt would see a lot of the new STT Pro's up there. I was quite frankly surprised by all the Cooper tires on 4X4's up there. It made me think what the hell am I missing? Not any longer.

    I had Trail Grappler M/T's. Definitely a decent tire, although I wasn't even remotely impressed when highway driving in the snow even though the Graps are M&S rated. Very good in deep snow by the way. Tread wear just average. Louder than the STT Pros. The Pros have a lot more siping. The Pro's are $125 cheaper and just as good, if not better IMO. I need to do some winter driving but all the reviews for winter driving are positive. I still think the Good Year DuraTrac is the best all around non M/T tire for the money.

    I can't speak on that as I ran the Nitto Terra Grapplers- not the trail grapplers.
    The Terras are an A/T tire.

    Awesome review! These are definitely some amazing tires. I made a review also for these https://www.tundras.com/threads/cooper-stt-pro-review-all-you-want-to-know.3850/#post-64388

    People need to understand although these are considered a Mud tire, they are actually built for the road and hwy as well. I have driven with these 90% road/hwy and these perform amazingly! Road noise is low, amazing traction and cornering. Not to meantion the armor-tek 3 carcass. I never really worry about where I go with these tires as they are built strong.

    Nice review too! Coopers tread engineers hit the nail on the head with the Pro's. Expect copy cats from Nitto and Toyo very soon. The S/T Maxx doesn't actually suck either for a hybrid tread AT version.

    Definetly get the PRO's you! You will be happy you did. Ive had mine for about 7 months not with over 10k miles on it. Tread wear seems to be surprisingly great on these. I Barely dropped 1/16 of tread in both front and rear since purchased. Rotated every 5 k

    Just buy a few cases of Kraft mac & cheese, maybe a case of rice-a-roni for a change in menu, use the rest for the STT's. See how easy that was???
