There is an area where the AT3 XLT excels, though, and that’s towing and hauling. Again, it’s not a class-leading tire in this regard, but it is out there. Your truck or SUV will feel stable, even at higher speeds, with good traction for acceleration and short stopping distances. Nonetheless, when it comes to traction and stability, the AT3 XLT works very well. And Cooper already has such a product in its lineup – it’s called the Discoverer AT3 4S. Some people might want that, but for general driving, a more responsive tire is better. What that means is that the tire won’t be as responsive and feel more truck-ish. How does it behave on a dry tarmac?Īs a result of the off-road-focused design, the Discoverer AT3 XLT could feel a bit more cumbersome in the corners. Cooper Tire also provides a 60,000-mile treadwear warranty, which is outstanding for LT-metric heavy-duty tires. The AT3 XLT is among the most durable all-terrain tires, with very good resistance to cuts and chips but also long treadlife. Thus, when the tread depth reaches the lowest point, the TWI’s will be flush with the rest of the tread.įortunately, that won’t happen soon. These are narrow rubber bars that sit recess into the grooves, in this case, 2/32 inches from the bottom, which is the minimum tread depth on this tire. The Discoverer AT3 XLT features the industry-standard tread wear indicators (TWI’s). Ultimately, the Snow Groove Technology with saw-tooth block edges improves traction in snow. The tread pattern also features stone ejectors, as well as Rugged Traction Shoulders for hardpacked surfaces. Meanwhile, the Durable Tread Technology gives the tire a very long treadlife.įurthermore, the Discoverer AT3 XLT features the Even Wear Arc that optimizes the footprint for even wear and Cooper’s Whisper Grooves design to quieten the ride. For starters, the tire is made from a shred-resistant silica-based compound, which should resist cuts, chips, and punctures better. The Discoverer AT3 XLT has all bells and whistles that Cooper has at its disposal. What are the features of the Cooper Discoverer AT3 XLT?
