Awesome tires!

I have had my Copper AT3W for about 3800 miles. They are still in fantastic shape. Treadwear is excellent, road noise minimal. Wet traction is amazing! Dry excellent. I have not run this set in the winter yet but I have run same tire in the past and my experience was excellent in snow.

Great tires, smooth and quiet.

Bought these for my 2017 Wrangler because previously I had purchased them for my 21 Gladiator. Aggressive looking but quiet and smooth. Great traction in all circumstances. The 35" that I have on my gladiator have 40K miles and still plenty of tread. You will get the 60K miles out of these.

An all season, all terrain tire, Cooper Tires' Discoverer AT3 4S is designed for use on light trucks and SUVs and offers drivers grip on rocky, smooth, wet, and snowy surfaces plus a 65,000 mile limited tread life warranty.



Features & Benefits

  • All-season tread
  • Outlined White Letter (OWL) or Black sidewall depending on the tire's size
  • 65,000-mile limited manufacturer tread life warranty
  • Features a Three Peak Mountain Snowflake certification thanks to its ability to perform in severe snow

Whether conquering trails on the weekends or simply needing a tire that performs through snow and rain, today's light truck and SUV drivers often search for a tire that can do it all. Featuring Adaptive-Traction Technology that provides grip on any surface, the Discoverer AT3 4S from Cooper Tires combines on road comfort with off road durability. Saw shaped grooves within the tread deliver superior traction on snowy surfaces, which helps the Discoverer AT3 4S to stop 20 feet shorter on snow than leading competitors. Featuring a five rib, all terrain pattern that allows for strong off road grip plus improved wet and dry traction, the Discoverer AT3 4S includes zigzag sipes that improve stability and control while also forcing out stones to prevent damage.
