Cooper Discoverer Rugged Trek 265/65R18 116T MPN 171066005

Tundra owner who wants more tread than a highway A/T?

Rugged Trek is the middle-ground rugged option.

Cooper's Discoverer Rugged Trek in 265/65R18 116T is the more rugged pick on this Tundra table, checked against a comfort-first Bridgestone Dueler A/T Ascent and a Firestone Destination A/T2. It carries a taller, higher-load 116T rating and rugged-terrain styling, so it splits the difference between a smooth A/T and a knobby off-road tire. It leads when you want extra tread and load without going full mud-terrain.

Cooper Discoverer Rugged Trek 265/65R18 116T MPN 171066005 is an exact SimpleTire row promoted into the truck tire catalog for 2024 Toyota Tundra SR5 CrewMax 4x4 planning with official tire-family docs and a current seller price snapshot.

Choose it if

  • Cooper Discoverer Rugged Trek 265/65R18 116T MPN 171066005 is tracked as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.
  • The 2024 Toyota Tundra SR5 CrewMax 4x4 route keeps offset, diameter, load, and rim-width checks visible before the offer is treated as a match.
  • Seller price, rating context, warranty resources, exact tire specs, and fitment checks are present, but final stock and shipping terms still belong in checkout.
  • Use these full-size tire rows when the Tundra tire diameter, load rating, rim width, and service description match the route limits and the wheel offset stays inside the checked positive-offset window.

Pass if

  • The Cooper Discoverer Rugged Trek 265/65R18 116T MPN 171066005 is not the right choice when your truck falls outside 2022-current Toyota Tundra current full-size trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: TRD Pro, dealer-lift, hybrid, or aggressive-offset setups without their own route check
  • Choose another size or construction when load capacity, wheel width, offset, rubbing clearance, ride, or spare-tire needs point elsewhere.

Verify

  • Exact tire MPN, tire size, and four-tire price
  • Load range, service description, rim width, and tire diameter
  • Wheel offset, brake clearance, seller stock, shipping, returns, and installer requirements
  • The checked shelf is a 2024 Tundra SR5 CrewMax 4x4 route; TRD Pro, hybrid, dealer-lift, and aftermarket suspension packages need their own clearance and seller checks before inheriting this answer.
