Before delving into the following comprehensive examination, let us examine the remarks made by other users regarding the Cooper Discoverer ST Maxx, STT Pro, and MTP.

  • I recently embarked on a long road trip that covered 1,500 miles straight. I only stopped for food and gas throughout my journey, but the Cooper STT Pro tires I had equipped my vehicle with made the drive truly enjoyable. Having owned many different types of all-terrain and mud tires, I can confidently say these tires are a game-changer. They handled exceptionally well on the road and made the drive much smoother than other mud tires like mtrs or km2s would have. Overall, I am incredibly impressed with Cooper’s STT Pro tires and wish they had come out sooner!
  • After some research and pondering, I finally settled on the STT Pro for my vehicle. And I must say, I am pleased with them. One of my primary concerns was how they would perform on the highway, but they have surpassed my expectations. I noticed they were louder than the previous tires I had used – even more so than my old and worn-out KOs! That was quite surprising to me. But despite the extra hum, it is not bothersome to me, even when cruising at 75mph. It’s noticeable enough to remind me that these tires are designed for performance and durability.
  • Recently, I have had two different riding trips where I had the opportunity to test my ST Maxx tires. The first was a three-day camping trip two weekends ago, and the second was a day trip last Saturday. Both journeys required me to travel for about two hours each way at speeds ranging from 45 to 70 mph. What impressed me the most about these tires is their ability to maintain excellent highway manners like street tires. Overall, I am happy with the performance of my S T Maxx tires and would highly recommend them to any rider looking for reliable, high-quality tires.
  • Regarding off-road tires, the MTP and STT Pro are two popular choices that offer reliable performance for various terrain. The MTP is known for its decent winter capabilities on hardpack snow and ice, though adding siping may cause an increase in treadwear rate and a greater risk of chunking when driven off-road. This tire also boasts a 2-ply sidewall, which prioritizes ride comfort. However, if you frequently encounter rough or rocky terrain, the STT Pro may be a better choice with its 3-ply sidewall.

The Cooper ST Maxx may not be the show’s star, but it puts up an intense fight in an off-road performance. This tire performs exceptionally well in rough terrain thanks to its combination of rugged silica and angled ply construction. The ST Maxx is designed to withstand even the most rugged conditions, providing drivers with peace of mind on their off-road adventures.

The Cooper ST Maxx also boasts Amor Tek-3 technology, which can also be found in the STT PRO. This further proves that this tire is built for durability and longevity. While it may not be as impressive as its counterpart, the STT PRO, it still places a close second on our off-road performance analysis and is an excellent choice for those looking for a reliable and sturdy tire.

The Cooper Discoverer MTP is a tire that occupies the last position in its category. Unlike its competitors, the MTP lacks 3-ply construction, which explains why it performs poorly off-road. In general, there is concern about this tire because it only has a 2-ply sidewall. Some features of the MTP improve its performance on rugged terrains.

One of these features is the staggered blocks and alternating scallops on the shoulders of the tire. This help to provide improved traction on rough and uneven surfaces. The unique MTP design allows for better handling and stability when driving at high speeds.

Despite these positives, there are still concerns about the overall performance of this tire.

On-road Performance:

The Cooper MTP may look like a beast of a tire, but it offers surprising on-road manners. This is due to its unique combination of supersized tread blocks and chamfered edges, which work together to provide better stability and handling on the highway. These tires remain steady and predictable when driving at high speeds, making drivers feel confident behind the wheel.

The ST Maxx is another Cooper model that excels in highway drivability. While it’s marketed as an off-road-ready tire, the ST Maxx performs exceptionally well on paved roads. It offers impressive traction, handling, and steering response, making it a standout choice for those who split their time between city streets and rugged terrain. The ST Maxx proves you don’t have to sacrifice comfort or performance when choosing an all-terrain tire.

Snow and Ice Performance:

Off-roading is an exciting adventure for many, but it requires reliable tires. While most off-road tires perform well on rocks and gravel, wet conditions can be challenging for many. It’s crucial to have a tire that offers excellent traction in wet and dry terrains, providing safety and performance.

The Cooper STT Pro is one such tire that stands out. Its aggressive design allows it to easily tackle challenging off-road conditions while providing superior performance on wet and dry roads. The unique silica compound used in the tread enhances the grip on wet surfaces, giving drivers more confidence even in slippery conditions.

While other Cooper models like ST Maxx and MTP may not perform exceptionally well in icy conditions, they still offer impressive features that make them suitable for winter driving.

Noise Level:

Cooper ST Maxx (Less noise than STT Pro and MTP):

Notwithstanding the aggressive tread, the Cooper ST Maxx has impressed many drivers with its minimal road noise. Unlike other models that produce a roar while on the highway, this tire ensures smoother and quieter rides for those behind the wheel. The hybrid thread used in the ST Maxx works exceptionally well to reduce pattern noise. This critical feature sets it apart from other competitors in its category.

Another tire worth mentioning in terms of noise-dampening qualities is the Cooper STT Pro. This model sports a 3-2 rib pattern which cancels out road noise and provides quiet and enjoyable rides for long hours of driving. Despite being an excellent choice for heavy-duty purposes, it falls short compared to other models due to its lack of dedicated noise-reduction features.


Cooper ST Maxx:

When it comes to off-road adventures, having the right tires is crucial. While traditional off-road tires with aggressive treads are great for tackling rugged terrain, driving on regular roads can be a nightmare. The jarring effects of rocks and other road obstacles can make for an uncomfortable and dangerous ride.

This is where the ST Maxx comes in. Its unique hybrid tread pattern perfectly balances off-road capability and road comfort. With its unique design, this tire protects you from those jarring bumps while giving you excellent traction on even the most challenging terrain. Whether you’re heading out on a weekend camping trip or need to navigate some rough backcountry roads, the ST Maxx has got you covered.

Treadwear Warranty:

When it comes to purchasing off-road tires, there are several factors you should consider. While the ability of a tire to handle challenging terrain is undoubtedly important, it’s not the only aspect that matters. Warranty protection is equally crucial, as it guarantees that your investment will last and perform optimally for an extended period. Cooper’s limited warranty protection is one such option that offers peace of mind to drivers.

One notable aspect of Cooper’s warranty protection is its allowance for testing tires before committing to a purchase. Customers can test-drive their chosen models for 45 days, putting them through their paces on various terrains and in different weather conditions. This feature assures you that you’re making an informed choice about your tire selection.


When purchasing tires, price is often a significant factor that people consider. The MTP stands out as the lowest-priced tire on this list, starting from just $170. This may seem attractive for those looking to save money, but it’s important to remember that prices aren’t everything. Cheaper tires may wear out more quickly than their expensive counterparts, meaning you’ll spend more money on replacements in the long run.

On the other end of the spectrum, we have the Cooper ST Maxx – which is by far the most expensive tire on this list, with a starting price of $249. While this may seem steep at first glance, it’s worth considering what you’re getting for your money. The ST Maxx boasts a durable tread and robust construction that should last longer than some of its cheaper competitors.

Final Thoughts:

All three tires – Cooper Discoverer ST Maxx vs. STT Pro vs. MTP – offer excellent off-road performance and durability. The ST Maxx is a great all-rounder with good on-road manners, the STT Pro is best suited for extreme off-roading, and the MTP offers excellent traction on mud terrain. Ultimately, the choice depends on individual requirements, driving style, and budget. Investing in a high-quality tire that meets your needs for a safe and enjoyable driving experience is essential. So, weigh your options carefully before deciding and hit the trails with confidence!
