Description
Discoverer AT3 XLT All-Season. The Discoverer AT3 XLT Tire with Durable Tread Technology provides extreme durability for hauling heavy loads with less wear and are built to withstand ongoing assault from dirt and gravel. The AT3 XLT was designed to prevent shredding on rocky and gravel terrain while the rugged biting edges on the shoulder of the tire supply extra grip and resistance to punctures.
Even Wear Arc Technology. Cooper engineers designed the shape of the Discoverer AT3 XLT to strategically balance pressure at the tire-to-road contact area promoting even on-road treadwear and superior handling.
Whisper Grooves. The Discoverer AT3 XLT incorporates "Whisper Grooves" into the tread of the Tire to provide a sound barrier that greatly reduces road noise.
Stone Ejector Ledges. Cooper engineered Stone Ejector Ledges that easily eject stones and gravel to protect the Discoverer AT3 XLT from stone drilling into carcass as well as maintaining a clean tread for enhanced road traction.
Rugged Traction Shoulders. The Rugged traction shoulders of the Discoverer AT3 XLT provide increased off-road traction for rock crawling and mud handling as well as additional resistance to abrasion and punctures.
Application. This Cooper Discoverer A/T3 XLT Tire is designed for use on all makes and models. Sold individually.

These tires are beefy!
I really love how big these tires are, great in rain and on dry pavement but not sure about snow and ice yet.

2023 Rubicon - REDDER
SWEET!
Tires went on my baby BLACK Rubicon 2023 paired with candy red rims - it is definitely a high quality tire and also sweet on my eyes! Did not have a chance to test it off-road but is super sturdy on wet pavement.

So far so good!
Great for the multi-terrain use, feels great on the highway, and gets me going on the off road obstacles. Highly recommend it to people like me for the mostly daily, and the occasional off roader

2012 Wrangler - Tom
Great tire
Excellent customer support and shipping from ET. Tire is very smooth on the road, virtually no road noise from a 35 12.5x20 with this aggressive of a tread, I was pleasantly surprised. They grip the road well in wet conditions and with winter fast approaching in northern Ohio I’m excited to see what they’ll do !
