Toyo Open Country A/T III LT275/65R20

Does the Toyo Open Country A/T III LT275/65R20 earn its place over the Bridgestone Dueler A/T Ascent 275/65R18 116T MPN 009702 and the Bridgestone Dueler A/T Ascent LT265/70R18 124/121R MPN 009685?

Toyo Open Country A/T III LT275/65R20 is best for shoppers who want a balanced all-terrain with mature survey depth and a less extreme road feel than louder hybrid-style tires

The Toyo Open Country A/T III LT275/65R20 is on this shortlist for a specific truck and use, not because it beats the Bridgestone Dueler A/T Ascent 275/65R18 116T MPN 009702 and the Bridgestone Dueler A/T Ascent LT265/70R18 124/121R MPN 009685 on every line. The rows below keep included hardware, the fitment, and install effort in view before any seller price, so the trade stays yours to make.

Choose it, pass, or verify

A well-reviewed all-terrain tire for Silverado Trail Boss shoppers who want a balanced road/trail tire with strong survey depth and official warranty support.

Choose it if

  • Toyo Open Country A/T III LT275/65R20 is best for shoppers who want a balanced all-terrain with mature survey depth and a less extreme road feel than louder hybrid-style tires
  • Confirm exact size, load range, rim-width range, and service description before comparing seller prices.
  • Keep the Silverado 1500 LT Trail Boss 4x4 Crew Cab wheel offset and clearance limits visible because tire diameter alone does not prove the package fits.
  • This tire size is useful only when the full wheel-and-tire setup is checked. The LT275/65R20 size has to stay inside the Silverado 1500 LT Trail Boss 4x4 Crew Cab route's 34.2 inch tire-diameter limit and must be paired with the right load, rim width, and wheel offset.

Pass if

  • The Toyo Open Country A/T III LT275/65R20 is not the right choice when your truck falls outside 2019-2026 Chevrolet Silverado 1500 fourth-generation trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: Wrong load range or service description
  • Choose another size or construction when load capacity, wheel width, offset, rubbing clearance, ride, or spare-tire needs point elsewhere.

Verify

  • Load range and service description
  • Rim width and tire diameter
  • Wheel offset and full-lock clearance
  • The checked route is a 2024 Silverado 1500 LT Trail Boss 4x4 Crew Cab with factory-lift planning. Lower LT/RST trims, ZR2, heavy towing setups, aftermarket lifts, brake packages, and GMC Sierra equivalents need their own seller and clearance checks before inheriting this answer.
