Discoverer AT3 LT

Built for hard-working trucks that split time between pavement and rough roads, Robertson Tire offers the Cooper Discoverer AT3 LT in LT load range E fitments for towing, hauling, and year-round traction. The Cooper Discoverer AT3 LT tires are available here in sizes like 215/85-16, 245/75-17, 265/70-17, and 265/75-16 for drivers who need dependable grip on gravel, mud, and rocky surfaces without giving up everyday road manners.

Designed for heavy-duty pickups, midsize pickups, and body-on-frame SUVs, this model combines LT strength, load range E construction, and snow-rated traction with the three-peak mountain snowflake designation across Robertson Tire’s current catalog. A backed-by-catalog 60,000-mile warranty adds long-term value, while Even Wear Technology, Durable Tread Technology, Whisper Grooves technology, and stone ejectors help support durability, comfort, and more even tread life.

If you want an all-terrain tire that feels practical for highway commuting, jobsite travel, and occasional winter weather, the Cooper Discoverer AT3 LT tires are a smart fitment-led choice.
