BFGoodrich All-Terrain T/A KO3 LT275/65R20

Trail Boss on 20s -- KO2 familiarity or newer build?

KO3 is the newer, snow-rated 20-inch pick.

This is the newer BFGoodrich KO3 in LT275/65R20 (about 34.1 inch), a severe-snow-rated all-terrain aimed at Silverado Trail Boss builds, checked against two much shorter Continental TerrainContact sizes. The peers are highway 17-inch tires; this is a tall LT with winter certification. It leads when you run 20s on a Trail Boss and want a proven-style aggressive A/T that carries a 3-peak snow rating.

2019-2026 Chevrolet Silverado 1500 fourth-generation trucks when LT275/65R20 specs stay inside the route limits

Verify first

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.

Choose it when
Choose it when LT275/65R20 fits your Trail Boss inside the checked +18 to +32 mm offset window and you want a severe-snow-rated aggressive all-terrain.
Pass when
Pass when the load range or service description is wrong, when wheel width is outside spec, or on aggressive-offset, lifted, or trimmed builds that need their own clearance route.

A newer severe-snow-rated all-terrain tire for Silverado Trail Boss shoppers who want KO2-style familiarity with updated KO3 construction and current LT275/65R20 specs.

Choose it if

  • BFGoodrich All-Terrain T/A KO3 LT275/65R20 is best for shoppers who want a newer premium all-terrain with severe-snow credibility and a familiar bfgoodrich truck-tire story
  • 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 BFGoodrich All-Terrain T/A KO3 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.
