Cooper Discoverer A/TW Overview

Light Truck All Terrain Winter

An all-season, all-terrain tire, the Discoverer A/TW is designed for use on light trucks and SUVs and offers drivers strong on- and off-road capabilities along with a 50,000-mile limited tread life warranty.

Features & Benefits

  • All-season tread
  • Black sidewall
  • 50,000-mile limited manufacturer tread life warranty
  • Features a Three Peak Mountain Snowflake symbol thanks to its ability to perform in severe snow conditions
  • Drivers who want to conquer any terrain need to make sure their tires are up to the task, and the Discoverer A/TW from Cooper Tires does that and more for light truck and SUVs drivers. Featuring a siping design that optimizes all-terrain performance, the Discoverer A/TW includes twin tie bars within its tread that provide stability and confident handling while also reducing irregular wear. Self-cleaning grooves improve traction on snow and loose surfaces, and the Discoverer A/TW also features a snow groove that puts more rubber on the road to further boost traction on snowy roads. The Discoverer A/TW features a Three Peak Mountain Snowflake certification thanks to its strong abilities on snowy surfaces, making it a common choice for those who drive a Chevrolet Suburban or Tahoe, and other half-ton or full-sized pickup trucks.

I bought this tire to replace one that got a piece of metal through the sidewall. The other 3 have over 20,000 miles on them and are only 1/2 worn. No cupping and still quiet.
Bought these based on the good reviews. Had them on my 2014 Tacoma double cab. Wasn’t impressed at all. I must have got a bad set? They were completely dry rotted in less then 2 years and wasn’t impressed with the winter traction. Went back to general grabber at2, can’t beat them for the price.
