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 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.

Pros & Cons

No matter how much positive feedback a product can get, no product is perfect without flaws. Below is a summary of the pros and cons of Cooper Discoverer AT3 4S:

Pros
  • Ideal winter capability, high dry and wet on-road
  • Good off-road grip
  • Warranty up to 65,000 miles treadwear
  • Relatively comfortable
Cons

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 review, it’s still a nice option to take these tires home!

    For my second go around, I chose Discover AT3 tires and have been very pleased with the results. With winter quickly approaching, I opted to make a change in order to ensure better snow traction – happy that these proved far superior than their predecessor (Goodyear Wranglers).

    Even on soft sand they handled beautifully while providing fairly good adhesion on ice-covered roads – though no tire can guarantee such performance without studs installed. So if you’re an SUV or truck driver looking for dependable year round service out of your tires, then investing in some Discover AT3’s is truly worth considering!

    After 20,000 miles of exploration on my first set of Goodyear Coopers, I realized that 4WD became indispensable to tackle any grade or incline – a great investment for adventurous summer rides and exhilarating cornering!

    Having been loyal to this tire brand for the past two decades, I can vouch that they’ve kept me safe and sound on 3 large SUVs and a truck! The tires offer quietness, durability and great traction which has made them ideal for all styles of driving – no matter if you’re navigating through busy city traffic or hitting the upstate highways. And with how harsh winters in NY could be at times – these have proven their strength year after year.

    With 7,000 feet of elevation and all-season weather conditions in Vail Valley, it’s no wonder I chose Coopers Tires for my car. For the past 13 years they’ve been working hard to keep me safe on treacherous mountain roads with their reliable ATR 10ply & newer AT3s; full sized emergency vehicles use them too!

    Most recently I switched to P-Rated tires that promise a smoother ride than before – plus an impressive 4S tread life which is ideal for transporting my heavy trailer where traction counts most. Here’s hoping these Coopers can stand up against whatever Mother Nature throws at us!

    The winter treads offer an impressive performance for navigating icy roads. The wet braking and acceleration provide a reliable experience, allowing me to confidently drive in slippery conditions without having to switch into 4WD mode. Even after only driving it a few thousand times I can feel the traction instantly recovering if any wear does occur – making them ideal in snow-covered areas!
