BFGoodrich All Terrain T/A KO3 LT285/75R17 128/125S

The BFGoodrich All-Terrain T/A KO3 in size LT285/75R17 (part number 30398) is the third generation of BFGoodrich's legendary all-terrain light truck tire, built for drivers who demand serious off-road capability without sacrificing daily drivability. The KO3 is available in the E load range (10-ply rated) with a load index of 128/125S, carrying a maximum single load of 3,970 lbs at 80 psi. The raised white letter (RWL) sidewall gives the KO3 the classic look that complements lifted trucks, SUVs, and 4x4 builds.

BFGoodrich part 30398 features a reformulated cut, chip, and tear-resistant tread compound that delivers greater longevity and durability on gravel, dirt, and pavement. The symmetric non-directional tread pattern with interlocking tread blocks optimizes the footprint for even stress distribution and uniform wear. Broad shoulder channels and high void space efficiently evacuate water and reduce hydroplaning risk. 3D Locking Sipes run full depth and, combined with Snow/Mud notches, provide traction across varied surfaces including light snow. Alternating shoulder scoops claw into sand, dirt, and rock when the tire is aired down for off-road use, while Mud Phobic bars keep the tread clear of packed buildup.

BFGoodrich part 30398 carries the Three-Peak Mountain Snowflake (3PMSF) symbol, meaning it has been independently tested and certified to meet severe snow service requirements. The CoreGuard Technology extends a bruise- and split-resistant rubber compound down the upper sidewall for added protection against trail damage. Internal construction uses a triple-ply polyester casing, twin high-strength steel belts, and a nylon cap ply for high-speed durability. This tire fits any vehicle with a 17-inch wheel accepting LT fitment with a 7.5 to 9.5 inch rim width range.

BFGoodrich backs part 30398 with a 50,000-mile treadwear limited warranty for peace of mind on road and trail.
