Cooper Discoverer AT3 LT - all-season tires for light trucks, which are aimed at year-round intensive operation. This rubber was presented to the consumer in May 2018. The tires were introduced alongside two other models, the AT3 XLT and AT3 4S. Thus, the Diswarer range has grown significantly and now covers the entire off-road segment of the tire market.

Tires belonging to this model family have high traction characteristics, unsurpassed cross-country ability, and a high degree of the resource. According to the manufacturer, rubber has significantly improved performance properties compared to earlier representatives.

The Cooper Discoverer AT3 LT is a light truck tire with a symmetrical non-directional tread pattern designed for all-season all-terrain use in countries with mild winter conditions. They are characterized by reliable adhesion properties and effective braking that are not affected by weather changes, as well as wear-resistance and durability.

The Cooper Discoverer AT3 LT tires, along with the Cooper Discoverer AT3 XLT and Cooper Discoverer AT3 4S models, have entered the updated 2018 Discoverer AT3 range. Their appearance was due to the increased demand from owners of commercial vehicles for durable tires, which, moreover, could feel confident off-road and provide a comfortable ride.

2018 AT3 Extended Range Models

Because the Cooper Discoverer AT3LT tires are designed to carry heavy loads, their key feature is their high wear resistance, which is guaranteed by the manufacturer's patented Durable-Tread technology found in this off-road model. They prevent cuts and chips that are inevitable when driving on gravel for a long time.

Discoverer AT3 LT's innovative scratch-resistant rubber compound significantly improves the tire's rough terrain performance and reduces tread wear.

The tread pattern of the Cooper Discoverer AT3 LT provides not only uniform pressure distribution in the contact zone, but also stable handling. Called Whisper Grooves, special tread elements create a sound barrier that reduces road noise. Rock-repellent lugs on the walls of the circumferential grooves prevent stones and gravel from getting stuck in the tread, thereby extending the life of the tire.

The tread design of the wheel has hardly undergone any changes during the design and inherits the general outlines of the tread of the Discoverer AT3 wheel. The figure has a symmetrical appearance with large macroblocks. The tread blocks have special sipes of medium dimension to provide decent driving and traction qualities. Despite the rather short braking distance, according to preliminary estimates, tires can serve about 96 thousand km off-road or on a country road. It should be added that when assessing the wear resistance, the features of the operation of the wheels were also taken into account - the tire wear was assessed on the off-road.

Whisper Grooves technology involves the production of specially shaped grooves. The rubber grooves reduce resonance noise, so driving at speed is quite comfortable and quiet. Of course, the aggressive tread and rigid construction do not give the effect of complete silence, however, in comparison with similar models of other manufacturers, the Cooper Discovery AT 3 LT tires have a noticeably more pleasant level of comfort.

Z-grooves improve mud and water flow and help repel rocks and dirt. The depth of the channels is optimal to prevent aquaplaning.

The design features of the tire allow you to maintain the integrity of the wheel, as well as to have an impressive carrying capacity. In the production of the novelty of 2018, exclusively new developments in the field of raw material processing were used. First of all, the company introduced a new compound into the tire design with a large amount of polymer and silicon additives that prevent damage to the cord.

The Cooper Discoverer AT3 LT rubber compound offers more than just protection from the external environment. The new compound allows you to maintain elasticity and high-quality driving characteristics throughout the entire period of use. The impact of wear on the rubber is minimized. The clutch remains the same grip throughout the entire service life.

Rubber for SUVs Cooper Discoverer AT 3 LT is:

  • limiting wear resistance within 100 thousand km;
  • improvement of traction ability by 5-7%, in comparison with the previous tires;
  • The stable grip on wet, snowy, and dry surfaces;
  • acoustic comfort on an asphalt road;
  • the highest carrying capacity and decent driving performance when the car is loaded;
  • new compound.

The all-season Cooper Discoverer AT3 LT has been designed for the transport of heavy loads and is characterized by increased durability. Durable Tread Technology avoids deterioration in handling and flotation on mud and gravel. The new cut and chip resistant compound significantly improves the performance characteristics when riding on sharp stones and increases the tread resistance to wear.

The tire profile has been designed to evenly distribute pressure across the contact area of the tire to the road, further enhancing tread wear and mileage. Introduced in the Cooper Discoverer AT3 LT, the new sound barrier technology at the bottom of the Whisper Grooves tread reduces the level of road noise, and the rock-ejector lugs on the walls of the grooves increase the tire's durability.
