    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.
    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.

    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!

    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!

    I'm really considering these tires for my next set. My truck is relegated to weekend warrior/long trip duty. Any idea of these are much louder than my duratracs?

    The only true mud terrains I owned were on an 85 Blazer... so can't really compare that noise to a Tacoma.

    Which Duratracs? Compared to the Duratracs M/T; the Coopers are much quieter.

    They're louder than the A/T's but not obnoxiously loud like Toyo M/T's or something.

    I had Duratracs M/T's before...HOLY HELL those were loud.

    Almost all tires are quiet in the beginning. :spy:

    Just wait! :laugh:

    Seriously, though, good looking truck and nice review. :hattip:

    Figures the'd be a little louder, Thanks, which I knew somebody close by that was running them so I could hear them. Noise is not a huge issue except for an annual 1500 mile round trip.

    I'm actually a little worried about that. The duratracs started off very quite for as aggressive as they are, but then the wore and got quite a bit louder.

    Spend some quality time sound proofing your cab, it will make a tremendous difference in your travels.

    I had duracraps which I ran for 40K miles. I think I remember them getting loud around 20K of wear. I know some guys get more life out of them, but mine were pretty smoked at 40K. :burnrubber:


    These Cooper ST Pro's look pretty tough... I'm running Toyo MT which I love... When it comes time, though I'll shop the Coopers too. ;)

    Thanks! My duratracs got louder around 20k also. They only have about 30k on them now, but are chunked pretty badly in the tread and I've had 2 sidewall failures. Plus they(the remaining original ones) are around 5 years old. I'm looking at these for something that will be tougher in those areas.

    No clue TBH.

    I had the M/T's before. Horrible in snow and ice, very heavy, and very noisy.

    Would you recommend these tires for someone that spends 90% of time on road? I do occasionally like to go off roading and I do a lot of camping. I live in socal so I don't really deal with mud or rain just some snow during the winter months when I go snowboarding up in the mountains. I have a 2wd truck so I'm trying to get the best combination of at/Mt to make my life a little easier on adventures.

    I was looking at these tire really hard, I ended up going with the Cooper ST Maxx though. Although my truck is not a daily driver, it's a long way on the highway to the the places I wheel. You may want to check those tires out..... Aggressive AT may be the best bet for you. I had duratracs, but wanted the Coopers for there better puncture/sidewall strength. I tore up the duratracs pretty bad. I see lots of 2wd trucks with mud tires, but w/o 4wd, you really aren't getting the full benefit.

    Other than snow, and some occasional mud- I'm mainly on all paved road.

    I did my research on the duratracs and the consensus seems to be they tear/chip easily and don't wear very well so I've ruled those out. I'll check into the st Maxx, I've also been really intrigued by the new Nitto ridge grapplers just waiting on more reviews of those to come out. I still like the stt pro and all the reviews I've seen had nothing but good things to say so for now I'll keep them in the mix. Thanks for the reply.

    How's the ride and noise level?

    For mud terrains these aren't nearly as noisy as my Toyo M/T's were.
