Cooper Discoverer S/T Maxx Review

I have to admit that I am an avid off-road warrior, I thrive driving in muddy and rocky terrains, anything that makes things more challenging. However, without the proper vehicle and tires, it is pretty much impossible to do it. For that reason, I am a little more nitpicky when it comes to all-terrain tires, and today we have the Cooper Discoverer S/T Maxx. If I had to trust my off-road buddies, these tiers are pretty much the best to deliver a balance between amazing off-roading and comfortable asphalt performance. It seems a bit impossible but we will see.

Main Features Of The Cooper Discoverer S/T Maxx

Target Audience

The manufacturer has stated that these tires are designed for tough terrains, which can include anything forms rocks, gravel, mud and much more, yet while still delivering great on-road stability and performance. It has captured my curiosity and I have to see what these tires are capable of. Most of the time I have either seen a good on-roading performance with a sacrifice to off-roading or the contrary, but further testing should deliver a better idea about it.

Specs and Features

As proper tough off-road commercial-grade traction tires, the Cooper Discoverer S/T Maxx’s come with an extended feature and spec list that have impressed me from the get-go, but maybe it is all tech jargon and mix and match. So let’s start looking into them. The company provides a limited tread warranty for these tires for tire uniformity, workmanship, and materials for the whole life of the tire, which is pretty good to see. These also come in different sizes to suit different vehicles as they fit into light trucks, SUVs, jeeps. CUVs and even light vans, with rim sizes ranging from 15 to 20 inches.

First off let’s talk about the 3-ply Armor Tek-3 construction of these tires which is the best in the market in my experience when it comes to durability and enhanced strength. Moving on it also has new silica and natural rubber compound that is super tough, and it is guaranteed for chipping and cutting. This combines very well with the Armor Tek-3 construction, making this a great off-roading tire, at least in the paper. To make things better the company has also added an angled ply construction, which should spread the taken impact to keep the tire intact. The buyer feedback has confirmed this as well but we will see that in testing.

Moving on it has a hybrid 4-5 rib tread design which in theory should perform excellently in all-terrains on and off-road. I also liked the tread block pattern that allows the water to escape from under the tire effectively increasing the performance in wet pavement and mud. It is also packed with some nice extras including the stone ejector ribs, that are packed onto the lateral grooves to get rid of debris, stones, and mud. Without forgetting I should state that it has studdable lugs for those that require better snow performance.

First impression

The first thing that I felt when I saw these tires was that these are badass. These can definitely get through anything that is on their way, and yeah, they are pretty heavy and sturdy as well.

I installed these tires on the Ford Ranger, and I got to say that these looked exceptional on it. Then again after the first spin around the block, I didn’t notice any big difference between these and the regular touring tires, further testing will reveal their true nature.


During my two months of testing, I have put these tires through a lot of different scenarios, from dry and hot pavement to rocky off-roads, muds, and even some thick snow, which gave me a nice idea about these tires. I can say at first that these tires wear pretty evenly and exceptionally, they should deliver a pretty long tread life. Also, I have noticed that these deliver a pretty good performance when it comes to comfort and noise, even on highway speeds, which I clearly didn’t expect.

On dry traction these tires were, how should I put it, a little underperforming. Not bad by any means but not as much as I expected. Well, my standards are a bit high for these tires since I expect nothing but the best from Cooper. However, during driving on the highway, I noticed that they delivered a great deal of confidence and traction. During the rain, these were exceptional though, and I live in an area with a lot of rain during late fall. They definitely overperform in this department, mainly due to the 4-5 rib tread pattern and the hybrid compound of these tires.

When it comes to off-roading though, these tires have no competition, top-marks. They went through every terrain without any problem, mud, rivers, rocks, grass and even snow, the Cooper Discoverer S/T Maxx’s are definitely the best. These tires have no limits they can go through everything without a problem, traction and grip were all over the place, even when paired with heavier vehicles it posed no challenge for these tires. The drive quality was off the charts, no competition for these tires.


If you are anything like me, and want to enjoy a bit off-roading every weekend, but also want plenty of comforts when you are on asphalt, then these tires are your best bet. Then again these are well worth the price, and you shouldn’t worry about anything as the company definitely has outdone itself here.
