Cooper Discoverer RTX Reviews: Pros and Cons

  • Terrific traction

  • Worn out after 30,000 miles

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 Cooper Discoverer RTX Tire 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.

    Just finished a 64,000 mile set of Discoverer RTXs and loved them so much, I decided to look for another set. These were mounted on my RAM 1500 Express. I was impressed by their smoothness and how well they handled the truck’s speed. They were more responsive to puncture and handling than the SRAs included with the truck. I felt confident in the rain. They were great for all the miles.

    I had planned to purchase tires from a warehouse club a few decades ago, but I stopped at NTB first and got a great deal on a set RTXs. This was right before the worst winter Boston has ever seen! These tires were fantastic! They were quiet on the highway but had good responsiveness. I seldom had to use 4WD even on unplowed roads. My 500+ mile round trip to Vermont was regularly made by these tires. They had better traction than the Michelin LTX tire that I replaced. There is nothing better than knowing your truck or car can handle any driving conditions and won’t leave it stranded. The RTX makes driving in bad weather fun. I like to be that guy people can trust no matter what the circumstances are. This tire is a great choice.

    A 2004 Lincoln Aviator AWD is all I have to be excited about. It still runs great after 189,000 miles. Still a little smooth. These tires were installed last winter at B 4. They provide excellent snow grip. Although they can be a little rough when temperatures are below 20 degrees, the tires do become more comfortable as you drive. Now that summer is near, These tires ride extremely smooth in warmer temperatures. I hope this helps. Thank you for reading.

    These tires were a bargain price. However, after two years and approximately 20,000 miles, the treads are almost worn out. I now have to look for a new set.
    They’re great for lighter vehicles, though I don’t know if they would be recommended for heavy-duty pickups.
    They have been worn flawlessly even with no cupping. They provide quiet riding, down to 2/32 inches.

    Excellent tire! Although I don’t usually leave reviews, this tire impressed me enough that I felt compelled by its quality to share my thoughts with others. A well-performing tire is something I have valued and appreciated my entire life. This Disoverer is quiet and smooth, and it excels in all weather conditions. They are very reliable, even though they were purchased for a 2006 Expedition. I have driven them hard and they handle acceleration, braking, and cornering well on both dry and wet roads. They perform better than expensive tires, and even after five years, when the wear indicators have finally worn out, they still ride and handle great! This is hands down the best tire I have ever owned and the only one I will ever use on my Expedition.
