Cooper ST Maxx is the first to analyze on the list. Cooper Tire & Rubber Company has long been known for manufacturing great heavy-duty tires for automobiles, especially medium to heavy trucks and motorcycles. ST Maxx is one of their best products.
It features an extremely durable and efficient structure that can withstand the hardest terrains. The most highlighted feature is the Armor Tek3 construction, built to support the tread and sidewall under the weight and pressure from all directions.
Thanks to the surface designed with symmetric patterns with sharp edges, it adds more traction to the tire and prevents hydroplaning. The structure has stone ejector ribs and groovy walls to prevent small rocks from sticking while extending the tire’s expectancy by removing stone drills.
On icy or wet trails, ST Maxx shows its strength by draining the water away more quickly with the specialized patterns. The cut-and-chip resistance design works like road claws, improving balance when traveling on soft and unstable dirt roads.
Cooper offers various sizes for a wide variety of cars, including pickups, 4x4s, vans, SUVs, huge crossovers, etc. These tires can provide great performance in every terrain under snowy, dry, and wet weather.
The interior of the tires consists of two hardened steel belts to enhance the sustainability of the tread, along with the nylon protection above them. These features allow Cooper ST Maxx to utilize the total speed of the vehicle.
Last but not least, multiple plies constructed along the sipes help reduce the gap between the body cords on the sidewall. The reinforcement significantly improves the durability during high-speed traveling.
Some reviews pointed out that the tire’s resistance to puncture is limited. The damage becomes clear after traveling for 20,000 miles. They are also pretty loud, as the tread can cause a lot of noise while pressuring on the dirt, mud, and rocky paths.

This tire is designed specifically for medium-sized trucks, from pickups to military jeeps, to take on the extreme road types with amazing traction forces and durability. The patterns on the tread were computer-optimized to increase its performance to the highest.
Like Cooper ST Maxx, KO2 features a cut-and-chip resistant tread compound to extend its useful life. The sidewall armor has an extra thick layer of rubber which provides even more traction by the “road-claws” to help to steer on unstable dirt.
Not only that, these tires boast single strand beads that are wrapped into many layers to improve strength, which contributes to the wheel’s stability and boosts driving quality. This feature significantly facilitates driving under heavy snow, branded with the 3PMSF (three-peak mountain snowflake) symbol.
The internal structure of these tires includes a set of twin steel belts wrapped in a spiral shape by nylon, plus 3-ply polyester cords on the sidewall. Such structure is the secret of the tires’ strength and durability.
Due to their bulky and heavy sizes, the tires are difficult to balance after approximately 20,000 miles. There is a noticeable vibration, which can affect steering. The structure is thick and tough, so it is difficult to remove small rocks and debris once they get stuck in.
