Cooper Discoverer A/T3 XLT Overview

If the superhero concept were to be applied to all-terrain tire development, the result might look something like the Cooper Discoverer A/T3 XLT.

Everything about the Discoverer A/T3 XLT is pumped up, from its off-road capability and durability to its load ratings and long tread life. The Discoverer A/T3 XLT leaves no question, it belongs squarely at the heavy-duty end of the all-terrain tire spectrum. It offers a diversity of off-road, towing, and hauling talents that only the most robust tires in the all-terrain tire category can deliver.

Cooper’s been in the tire business since 1914, and throughout that 100+ years they’ve made no shortage of high-quality truck tires beloved by enthusiasts. The Discoverer A/T3 XLT is part of the latest generation of Cooper all-terrain tires. The XLT builds upon the original Discoverer A/T3, which was a roundly successful all-terrain tire, and a favorite among 4x4 enthusiasts since 2011.

Here are a few things to know about Cooper’s most versatile and capable all-terrain tire:

1. Specifically designed to withstand wear under heavy load

Cooper’s Even Wear Arc Technology helps ensure even and long wear, especially when under heavy load, which is where most tires struggle to maintain ideal wear characteristics.

The contour and shape of the Discoverer A/T3 XLT facilitates even dispersal of weight across the tire’s contact patch, which prolongs tread life and also improves tire and vehicle performance in extreme towing/hauling conditions.

“Tire shape engineered to strategically balance pressure at the tire-to-road contact area promoting even on-road tread wear and superior handling.” – CooperTire.com

2. Incorporates mud-terrain tire features for maximum off-road capability

The Discoverer A/T3 incorporates tread design features typically reserved for dedicated off-road tires, including:

• Stone Ejector Ledges sit in the tread voids and work to eject stones and gravel, which keeps the tread clear of accumulating debris and the tire tread at maximum function. These ledges also help guard against tread damage caused by rocks embedding in the tread.
• Rugged Traction Shoulders contribute additional lateral grip during rock crawling, as well as when churning through soft soil and mud.

• Cooper’s Durable Tread Technology is specifically designed to prevent tread degradation and shredding on rocky and gravel roads, even when under additional load during hauling or towing.

“And off road, the AT3 XLT delivered on its pedigree. It got us through dirt, gravel, inclines, and rocks with minimal slipping or sliding. With less tire pressure, it would have performed even better.” – OffRoadExtreme.com

3. Cooper’s Whisper Grooves technology limits road noise

Cooper’s infused the Discoverer A/T3 XLT with all types of heavy-duty qualities, but with limited downside when it comes to routine on-road commuting.

Much of that achievement is due to Cooper’s Whisper Grooves, which work to quiet the irritating road noise typically associated with aggressive all-terrain and mud-terrain tires.

4. Delivers most of the off-road performance of a mud-terrain tire, but without compromises

A look at how Cooper compares the Discoverer A/T3 XLT to more extreme mud-terrain counterparts like the Discoverer STT Pro reveals its advantages, especially for most vehicles that are used on an everyday, on- and off-road basis.

The Discoverer A/T3 XLT delivers the majority of mud-terrain off-road capability, but with tangible advantages in terms of practical on-road use.

“Awesome Tire!

Put these on my 2017 RAM 2500 and love them! I believe Cooper has set a new standard in all-terrain tire. They are great on gravel and great in heavy rain so far from what I have experienced in 5,000 miles. Also no road noise so far.”
