BFGoodrich All Terrain T/A KO3 LT315/75R16 127S

The BFGoodrich All-Terrain T/A KO3 in size LT315/75R16 (part number 19117) is the third and latest generation of BFGoodrich's iconic all-terrain light truck tire, engineered for serious off-road performance and reliable everyday use. This size carries a Load Range E (10-ply rated) construction with a load index of 127S, supporting a maximum load of 3,860 lbs at 65 psi. The raised white letter (RWL) sidewall is the signature look for builds that need functional capability and visual presence.

BFGoodrich part 19117 measures 34.6 inches in overall diameter with a 12.4-inch inflated width, making it a popular choice for Jeep Wrangler JK and JL builds, Ford Bronco, Ram 2500, Toyota Tacoma, and similar platforms. The tire features a reformulated cut, chip, and tear-resistant tread compound for greater longevity across gravel, dirt, and pavement. The symmetric non-directional tread pattern with interlocking tread blocks optimizes even stress distribution and uniform wear. Full-depth 3D Locking Sipes and Snow/Mud notches deliver traction in rain, mud, and winter conditions. Alternating shoulder scoops provide clawing traction in sand and rock when aired down, while Mud Phobic bars keep the tread channels clear of buildup.

Part 19117 carries the Three-Peak Mountain Snowflake (3PMSF) symbol, independently certified to meet severe snow service standards. CoreGuard Technology extends a bruise- and split-resistant rubber compound down the upper sidewall for additional protection against trail damage and sidewall impacts. Internal construction uses a triple-ply polyester casing, twin high-strength steel belts, and a nylon cap ply for high-speed structural integrity. BFGoodrich backs part 19117 with a 50,000-mile treadwear limited warranty.
