Cooper Discoverer AT3 4S reviews

As trucks and off-road vehicles become more and more popular, the demand for their spare parts also increases, in which tires are an extremely important part. Being a familiar name in the truck tire market, is this tire that good? Check out this Cooper Discoverer AT3 4S review to find out!

Introduction 

The Cooper Company 

Cooper is an American tire brand with its headquarters in Ohio, USA. The famous brand owns four main manufacturing facilities in Ohio, Mississippi, Arkansas, Mississippi, and several other Europe, Mexico, and Asia. 

With more than 100 years of construction and development, Cooper has become one of the most prominent names in the automotive tire market worldwide. The company’s products are always durable and high in safety thanks to strict production processes.

The Product Line

Cooper Tires‘ tire lines are quite diverse and suitable for many different vehicles such as crossovers, luxury SUVs, real SUVs, etc. The Cooper Discoverer AT3 4S for off-road trucks is currently the tire model that receives the most attention from customers.

The Features Of Cooper Discoverer AT3 4S

Overall, the enhanced features are the most appropriate explanation for this tire’s massive support from customers since its initial release.

The Discoverer AT3 4S is ideal for pickup trucks, large SUVs, and crossovers. It is the perfect combination of off-road grip and comfort that drivers need since it can grip the road or other surfaces. Thanks to this feature, your car can confidently move even in areas with heavy snowfall.

Its zigzag grooves and serrated technology help this Cooper tire move in the snow much better than previous versions because it helps generate more traction. The five-rib design also makes the AT3 4S more suitable for terrain types such as sand, gravel, soil, and rock.

In terms of dry handling and traction, the Micro-Gauge ZigZag sipes help it stay balanced if it has to move on slippery surfaces.

Additionally, the dual-layer construction of polyester and nylon adds stability, durability, and responsiveness to this representative of Cooper. It also helps your vehicle to move more smoothly and quietly.

Cooper Discoverer AT3 4S: Tire Drive Test 

After taking in all the features of this popular tire, it’s time to dig in some of our experiences using it!

Are The Features Of Cooper Discoverer At3 4s True To Actual Use?

It is always better to try the product to make the correct judgment. As people who have driven with the AT3 4S, here are our thoughts on this tire:

First and foremost, its dry performance impressed us. This tire model had no problems with dry tarmac. It did well in corners, and the navigation was pretty neat.

There is a small note here that driving speed would affect the traction of the AT3 4S. The faster you drive, the less grip you have on the road. However, I find this not too serious because not everyone is a speed lover, and this tire is for SUVs or trucks, not race cars.

Regarding the wet-dry performance, this tire can move well on slippery and wet roads. The road grip of the AT3 4S is quite excellent. If compared to when traveling on a dry road, the traction has decreased but not too much.

So what about snow? Normally, snowmobiles require specialized tires with a soft structure. Regular tires will not perform to their full potential in the winter, and the Cooper Discoverer AT3 4S is no exception. Still, we highly recommend it because it’s perfect for casual drivers.

One more thing that we want to mention is noise. Like other off-road tires, the AT3 4S emits noise even on highways. This flaw is the only point we hope Cooper can improve on in the future.

In general, we have had quite a comfortable experience with this tire line except for some minor drawbacks.

Which Customers Will Be Suitable For This Type Of Tire?

The decision depends on your preferences and needs. If you need a light off-road tire and have to drive all year, the Discoverer AT3 4S could be the tire you’re looking for.

As analyzed above, this AT3 4S tire is a model that can travel on many types of terrain, in any weather conditions, with high safety, and ideal warranty. It is a relatively good choice for those who use trucks or SUVs. Despite some of the drawbacks we have mentioned above on this Cooper Discoverer AT3 4S review, it’s still a nice option to take these tires home!

    This is my second set with Discover AT3. They are my second set of Discover AT3. This is because they were very similar to the first set. These tires are far superior to the Goodyear Wranglers I had on my Jeep. These were changed a little early due to winter approaching and I wanted a better snow tread. These tires are great for driving on the beach. Even the soft sand is not an issue. They were fair on ice, as no tire is great on ice without studs. These tires are a great choice for anyone who drives an SUV or truck.

    I have two sets of Cooper Discoverer AT3 tires. I used to only use BF Goodrich AT Radial tires. The Cooper is a better tire than the competition. These tires can do all I need them to.

    The second set of Coopers… Great tires! 4WD is great for summer riding and cornering. Coopers was my first set of goodyears OEM tires. After 20,000 miles, I realized that 4WD was necessary to get the car started at any grade or incline. They are fantastic.

    These tires are durable, quiet, and traction-enhancing. I have switched to them on 3 large SUV’s and 1 truck in the past 15-20 years. These tires are great for driving on highways or in the city, as well as the upstate NY winters.

    At 7,000 feet, I live in Vail Valley. These tires are excellent for all seasons. Cooper tires have been my choice for 13 years. I used to use the ATR 10ply. Two sets of Cooper tires gave me 50k miles on my old Titan. Many full-sized emergency vehicles in the mountains use the ATR 10ply and the newer AT3s. They are able to withstand all weather conditions and provide excellent traction.

    P-Rated tires were the best option for my Chevrolet 1500 series. I have a lift and wheels that require 10 plys, so I wanted the ride to be as smooth and comfortable as possible. The older AT3 P-rated tires got me far less mileage than the newer ones. I’m hopeful that the AT3-4S P rated tires will have a longer tread life. They are quieter, more comfortable and provide a solid sidewall to support my 7K lb trailer.

    I find the winter tread to be as good, if not better than the older ones I’ve had. I don’t often switch to 4WD when there is snow on the roads. The snow, wet braking, and acceleration are excellent. They are predictable and quickly regain their traction if the tires do wear. They have only been driven a few thousand times so I can’t comment on their wear.
