Back in August, we were lucky enough to receive a set of Cooper Discoverer AT3 XLT tires. Big, beefy, but also subdued on the road, the XLTs were a tremendous tire that we were stoked to test out, and we went with a 2018 Wrangler JL as our platform. Our initial impression was that the XLT was a terrific tire, but is that still the case?

We caught up with Adam Montiel of MaxTrac Suspension, the company that owns the Jeep Wrangler. Adam has had the most experience with driving the Jeep since the installation, so he was the best man to talk to about how the XLTs have performed over time.

In our conversation with Adam, we learned that the Jeep has made treks all over Southern California, totaling about 3,000 miles. “We’ve driven the Jeep to several locations,” he said. “We’ve been to the Oceano Dunes, Holy Jim Trail, and Big Bear Lake.”

This has exposed the XLTs to a variety of terrains, including dirt, rocks, and sand. “I’m impressed with the XLTs,” said Adam. “I’ve taken it off-road many times and rarely had to use four-wheel-drive with how grippy the tires are. Even on the sand, I was waiting for the tires to tell me to air down, but I never had to. The only time I aired down was at Big Bear.”

On the street, the XLTs have performed as well as ever. We noted how refined the ride was on asphalt, and it seems the XLTs haven’t lost their edge. “The tires are very quiet on the street and have good manners,” said Adam. “There’s no road wander, even while driving on streets with cracks.”

So far, the wear characteristics of the tread are optimal. “It’s very minimal,” commented Adam. “The wear is even and normal for how much mileage we’ve put in.”

The Discoverer AT3 XLT continues to be a home run of an all-terrain tire, taking the MaxTrac JL to and from work and trails. We recommend you visit the Cooper website to find out more about the tire and which size is right for your rig.
