Product Details

The Cooper Discoverer Stronghold AT is a rugged all-terrain tire engineered for light trucks and SUVs that demand year-round traction both on and off the highway. Sized at 275/60R20 with a load index of 123/120 and speed rating of S, this tire delivers the durability and performance needed for work and adventure.

Key Features:

  • Three Peak Mountain Snowflake (3PMSF) certified for severe snow service, providing confident winter traction without sacrificing all-season versatility
  • Symmetrical all-terrain tread pattern balances off-road grip with on-road comfort and reduced road noise
  • Advanced tread compound engineered for extended treadwear and cut/chip resistance on gravel and rough terrain
  • Wide circumferential grooves evacuate water, slush, and mud for enhanced wet weather handling and hydroplaning resistance
  • Reinforced construction with a robust internal structure to handle heavy loads and resist punctures
  • Aggressive shoulder blocks provide additional biting edges for traction in loose dirt, mud, and snow

Ideal for truck and SUV owners who need a tire that transitions seamlessly from highway commuting to weekend trail running, the Cooper Discoverer Stronghold AT combines the comfort of an all-season tire with the capability of a true all-terrain design. Whether you're towing, hauling, or exploring unpaved roads, this tire is built to handle the challenge.
