Cooper Discoverer RTX Reviews

Cooper Tire & Rubber Company is headquartered in the United States. The company has always been renowned for its variety of top-notch tire collections. Therefore, we will analyze and review their pretty new product line called Discoverer RTX.

The best thing about this manufacturer is that their tires come with a warranty. Moreover, the mileage warranty and 45-day road test ensure your safety and satisfaction with the product.

Specifically, Cooper Discoverer RTX is a light weight, deeply threaded truck tire featuring a robust and aggressive design. This tire is equipped with great traction on and off the road, so you’ll find it handling traction pretty well, both in the snow or on soft surfaces.

Here are the primary specifications of the Cooper Discoverer RTX We Tested:

  • Tire size: 235/75R15
  • UTQG: 500 A B
  • Load range: STD
  • Sidewall: OWL
  • Approved rim width: 6 – 8
  • Measured rim width: 6.5
  • Section width: 9.3
  • Overall diameter: 28.66
  • Tire weight: 31
  • Max load: 2039
  • Tread depth (1/32″): 13

Pros and Cons

  • Terrific traction
  • Quiet driving
  • Sturdy tread
  • Equipped with useful stone ejectors
  • Perform under many circumstances, including rain, snow, dry surfaces, and off-road
  • Worn out after 30,000 miles
  • Rugged look

Tire Drive Test

We have just completed a 64,000-mile run using Discoverer RTX tires, and we were so pleased with them that we went out and bought another set. We were surprised at how excellent its traction was, and these tires handle our truck’s speed perfectly.

In addition to the satisfying quiet drive, we found no difficulty handling our truck under the rain. The stone ejectors are a big plus for Cooper, although we don’t know how long it’s going to last until we have to replace them.

After a few trials, this tire left such an impression on us that we felt obliged to tell others about how amazing they are, especially for the price. Because we have spent a lot of time on racing automobiles and motorcycles, we truly appreciate this product.

This Discoverer RTX is not only quiet and smooth, but it also performs well in every circumstance, including braking, sudden turns, acceleration, and even off-road.

The only problem with these tires is their rugged look. Cooper Discoverer RTX is not suitable for you if you prefer more medium-sized, elegant sets of tires. Besides, you are likely to need to work on fixing or replacing new sets of tires after you’ve reached 30,000 miles.


With this reviews, we have come to the conclusion that it would be a great choice for your truck. Not only does it handle abrupt movements perfectly, but it also performs amazingly under all conditions.

    I’m delighted to have upgraded my 2014 GMC 1500 with these new tires! They not only provide a quiet and comfortable ride, but also great traction for all of my outdoor adventures like hunting and fishing. All in all, I’m thrilled about this purchase.

    It was an absolute pleasure driving the 64,000 miles of epic adventure with my Discoverer RTX tires. They glided effortlessly on my RAM 1500 Express and handled its wilder moments superbly – better than even the SRAs that came included! I felt perfectly safe in stormy weather too; these wheels were truly a reliable companion for every mile.

    Years ago, I decided to take a chance on NTB and their RTX tires. Little did I know that the decision would prove invaluable during one of Boston’s worst winters! They had superb responsiveness, and cruised quietly down highways while being able to confidently tackle any driving condition thrown at them – even unplowed roads rarely necessitated 4WD activation!

    My long drives upstate were made much more enjoyable with my newfound Tyre confidence; it was like being in control no matter what mother nature threw our way. The Michelin LTXs didn’t stand a chance compared to these trusty RTXs- perfect for those unpredictable conditions who want peace of mind when navigating wintry terrain.

    A 2004 Lincoln Aviator AWD may not seem exciting, but it delivers true performance even after 189,000 miles! Last winter I installed tires that provide amazing snow grip and have given me a smooth ride in warmer temperatures.

    Even when the temperature drops below 20 degrees they remain comfortable under my feet while driving – so no matter what time of year you’re behind the wheel this car still has your back. Thank you for taking the time to learn more about its capabilities!

    These tires were an absolute steal – but, unfortunately, their long-term performance wasn’t quite as good. After two years and over 20,000 miles of flawless driving I’m now looking for a new set to replace them.

    Even though these are great for lighter vehicles like sedans or SUVs it’s probably not the best choice if you own a heavier pickup truck. The ride was always comfortable with no noise even once they had worn down to 2/32 inches of tread!

    This Discoverer tire has been a pleasant surprise – providing an impressively quiet and smooth ride, all while ensuring reliable performance. Its extraordinary ability to handle acceleration, braking and cornering on both dry and wet roads was more than I could have asked for in this 2006 Expedition!

    After five years of driving these tires hard, their quality still remains consistent even when the wear indicators are worn out- making it hands down the best tire experience one can ask for.
