A Brief History of Cooper Tires:

Cooper is an American manufacturing company that started its journey in 1914. Though they began their journey with tire patches and repair kits, soon they became one of the main replacement tire suppliers in North America. Now their products are compared with the most renowned brands like Michelin and Bridgestone. 

The tires are considered the most affordable on the market with exceptionally good qualities. Cooper also had Original Equipment (OE) contracts with brands like Volkswagen, Mercedes-Benz, and Ford. They manufacture tires for cars, SUVs, trucks, minivans, and off-road vehicles. Where other tires cost around $800 to $1000, Cooper’s provides high-quality tires at a cost of around $600 to $800. 

Cooper ATW Vs. AT3: Differences

General Durability

The most important factor in all-terrain wheels is durability. When it comes to durability, the Cooper Discoverer ATW falls slightly short of the Discoverer AT3. The latter has a longer lifespan than the former.

Carcasses and Sidewall Durability

Experts believe that carcasses and sidewalls are another way to determine a tire’s longevity. Two-ply polyester casing, a single-ply nylon reinforcement, and two high-strength steel belts are used by the manufacturer on both tires. ATW and AT3 share a common carcass. 

The difference is in the sidewalls; AT3 has the thickest sidewall, making it the most durable. ATW, on the other hand, has a thinner sidewall and a lower load range, making it less durable than AT3. However, there are no significant differences between ATW and AT3 regarding durability.

Off-Road Performance

Off-road performance is the main attraction of all-terrain tires and Cooper’s Discoverers are in a top position. The Discoverer AT3 is the best choice for off-road performance because it is designed to withstand extreme pressure and heavy loads. That doesn’t mean ATW isn’t good. When comparing these two, AT3 outperforms ATW in terms of off-road performance.

Winter performance

There is no worthy opponent to challenge their performance in winter performance, in particular snow traction. In severe winter conditions, Discoverer ATW is the most viable option for SUVs and vehicles weighing less than 2 metric tonnes. AT3, particularly its 4S and XLT versions, is ideal for heavy applications and vehicles weighing more than 2 tonnes for snow traction. 

Dirt Traction

Manufacturers pay special attention to this feature, particularly in countries such as the United States. In the United States, it is common to have to deal with dirt. Though both perform well in dirt, experts prefer AT3 because of its deep sipes that allow for smooth performance even on dirt.

On Mud

When it comes to mud performance, AT3 lags behind ATW. The deep tread made AT3 difficult to navigate in the mud. Though both have a limited capacity for self-cleaning, AT3 is more problematic in this regard. ATW tires can maintain a higher level of consistency in mud.

Fuel Efficiency

The fuel efficiency of a product is determined by its weight. The more weight there is, the more fuel it consumes. Since ATW weighs approximately 61 pounds and AT3 weighs 37 pounds, ATW is less fuel-efficient than AT3. 

Road Noise 

ATW comparatively makes more noise than AT3. For pickup trucks, the noise should not be a major distraction, but constant road noise from one’s own vehicle can ruin the driving mood and comfort. On the other hand, AT3 rarely makes any noise. 

Cooper ATW Vs. AT3: Similarities

Gravel performance:

Both ATW and AT3 perform exceptionally well on gravel. Also, they are made of top-notched rubber and their strong sidewall protects them from any punctures.

Air-down performance:

ATW and AT3 are both trustworthy options for air-down driving as well as rock crawling. Their flexibility and strong structure made them best at air-down driving conditions. However, among the three versions of AT3 tires, the 4S is the most viable option for this. 

Dry road performance:

For all-terrain tires, dry roads are not a big deal and these two are very good at it.
