Product Details

The Cooper Discoverer Stronghold AT is an off-road all-terrain tire engineered for drivers of pickups, crossovers, and SUVs seeking dependable traction off-road with on-road comfort. Purpose-built to conquer dirt, gravel, mud, and city street challenges, this tire delivers versatile performance for both work and adventure.

Key Features:

  • 3D sipe technology in the shoulders provides stability in cornering
  • Wide open grooves in the tread offer solid traction in dirt, gravel and soft surfaces
  • Specialized rubber compound forms the base of its next-generation all-terrain tread pattern
  • Tough, interlocking tread blocks for off-road action with individual lug designs for improved tread-life and resistance to irregular wear
  • Strong shoulder design features scooped tread edges, wide tread grooves and sidewall hook pattern for grip and traction throughout tire life
  • Strategically designed tread lugs resist cracking, tearing and rounding, with ledges between lugs preventing stones from getting stuck

This tire handles light snow capably enough to meet the tire industry's severe snow service rating and displays the three-peak mountain snowflake (3PMSF) symbol. Cooper offers a 60,000 mile treadwear warranty with this model. The LT275/55R20 size features a 120/117 load index with S speed rating (112 mph), Load Range E (10-ply rated) construction, and 16/32" tread depth for exceptional durability and load-carrying capacity.

Nice and easy

Everything went well. I'm not sure why a blower fan would be made with any metal that could corrode and yet that's what happened to the old one that is NOT that old.

I was extremely pleased with the purchase price and very fast shipping of my order. It arrived sooner than expected.

My experience was great

Very good and reliable service

matches wheel I just destroyed on boat trailer.

Ok
