Cooper Discoverer AT3 4s Review 2024 [Off-Road Tests]

Cooper Tire has expanded its A/T3 series with the Discoverer AT3 4S. As a new addition to the AT3 lineup, the 4S has one significant selling point: its ability to provide excellent snow grip.

Treadmill manufacturers have made purchasing new tires a problematic task. If you had to select between the Cooper Discoverer AT3 and the Cooper Discoverer AT3 4S, you wouldn’t have to do so because the AT3 is no longer available. Several years ago, Cooper added the AT3 4S, AT3 LT, and AT3 XLT to its line of AT3 tires, all of which are designed for lifted vehicles and intensive off-road use, to the AT3 family. A whole redesigned tread compound and other extra features are included in the AT3 4S, and also the cooper discoverer at3 noise review is also mentioned in detail that it does not create sounds and noises.

  • Snow Groove Technology is the name given to Cooper’s serrated tread blocks. According to Cooper discoverer AT3 4S Review snow, the “saw-tooth” design keeps the snow in place for better traction in icy conditions. AquaVac channels are included in the tread of the Discoverer AT3 4S to help spit out water and prevent aquaplaning in all weather conditions, not just snow.
  • Another part of the tread is the five rows of tread blocks designed and developed to give traction on and off the road. Lastly, the AT3 4S has characteristic microscopic zigzag-pattern sipes in each tread block, which are another clear sign of winter performance and grip. These features come together to make the AT3 4S an approved winter tire with the three-peak mountain snowflake logo displayed on the sides.
  • Cooper places the 4S above the A/T3 as a decent all-terrain tire. As a result, it compromises some quietness and handling to provide the bundle it delivers so well. If you require even more off-road capability, Cooper has additional aggressive tires available.
  • The tire’s UTQG treadwear rating of 620 is impressive, given its off-road capabilities.

What to look for in Buying

  • Indeed, Cooper tires aren’t as well known as Michelin or Continental, but they’ve gotten to the top tier-one tire industry thanks to their impressive R&D efforts. Cooper is best known for its Discoverer tires, which are made for trucks and sport utility vehicles. In particular, the AT3 and the cooper discoverer at3 4s winter review and the cooper discoverer at3 4s towing check are compatible for both things.
  • In the beginning, Cooper only made one AT3 tire, and it was discontinued. Both critics and spectators praised it highly. Since Cooper is from Ohio, he is familiar with the colder climates that AT3 4S performs best in, so the brand decided to release specific versions for more niche truck audiences like AT3 LT for trucks and designed for carrying loads, and AT3 XLT, which is designed for lifted pickups (like the Ford Raptor) and Jeeps.
  • When it comes to performance and pricing, Cooper is the clear winner in the market.
  • There are two high-strength steel belts within the Discoverer AT3 4S encased in a two-ply polyester case with a single-ply nylon cover. Tyre’s lifespan and life are improved as a result of this. The structure of the tire’s sidewalls is two-ply.

A serrated edge is added to the tread blocks of the AT2 4S, resulting in increased off-road traction, as opposed to the original AT2. The sidewall design is a more conservative approach to reducing road noise, yet it is no less compelling. With its three-peak mountain snowflake emblem certification for harsh winter driving, the 4S is a four-season vehicle. An additional 10,000 miles of tread life are also included in the warranty.

zigzags of sipes on the ground

As everyone who has ever created a snowball knows, snow sticks to snow.

Frequently Asked Questions

On slippery roads, how does it perform?

When designing a tire that can be used in various conditions, rain must also be considered. The AT3 4S didn’t blow me away as much as it did in the dry. The tires include

Aqua Vac channels and sips on the thread blocks. Driving in rainy and slippery weather, what does this mean?

Everyone is almost pleased with the AT3 4S’ performance. However, despite the unfavorable conditions, the tires held on to the road. They were able to maintain their grip on the street, despite the grip being not as excellent as in the dry. Having predictable tire behavior allowed us to anticipate when and how they would lose traction.
