Product Details

The Cooper Discoverer Stronghold AT is a rugged all-terrain tire designed for light trucks and SUVs that demand versatile performance on and off the road. Engineered with a symmetrical tread pattern, this tire delivers balanced handling and consistent wear characteristics while providing confident traction across multiple surfaces.

Key Features:

  • All-season compound optimized for year-round performance in diverse weather conditions
  • Three Peak Mountain Snowflake (3PMSF) certified for severe snow service, providing enhanced winter traction
  • Aggressive all-terrain tread design for confident off-road capability on dirt, gravel, and rocky terrain
  • Symmetrical tread pattern allows for multiple rotation options to maximize tread life
  • Load Range E construction with dual load ratings (129/126S) for heavy-duty hauling and towing applications
  • Advanced siping technology provides enhanced grip on wet and slippery surfaces

With its combination of all-terrain capability and winter certification, the Discoverer Stronghold AT is ideal for drivers who need a tire that can handle both daily driving and weekend adventures without compromising safety in challenging weather conditions. The 285/75R18 size fits popular full-size trucks and SUVs requiring a larger diameter tire with excellent load capacity.
