Built for the Trail, Refined for the Street: The KO3 in 33X12.50R15
The BFGoodrich All-Terrain T/A KO3 in 33X12.50R15/C 108R is the third generation of one of the most trusted all-terrain tires ever made, engineered with significant advances in tread compound, sidewall protection, and mud-shedding geometry over the KO2 it replaced. This LT-metric tire carries a C load range rating and 108R speed rating, making it well-suited to trucks and SUVs carrying moderate payloads. The KO3 tread compound is engineered for wet traction improvements of up to 20% over the KO2, while the aggressive 3-peak mountain snowflake rated tread pattern handles packed snow and light mud with confidence. CoreGard technology in the sidewall adds a full layer of puncture-resistant material to protect against the sharp rocks and debris that light-duty tires routinely surrender to.

Frequently Asked Questions
What is the BFGoodrich 88627?The BFGoodrich 88627 is the All-Terrain T/A KO3 tire in LT 33X12.50R15/C 108R. It is a third-generation all-terrain LT tire with a 3-peak mountain snowflake rating, CoreGard sidewall protection, and raised white lettering, designed for trucks and SUVs that split time between pavement and off-road terrain.
What is the difference between the BFGoodrich KO2 and KO3?The KO3 improves on the KO2 with a revised tread compound for up to 20% better wet traction, updated CoreGard sidewall construction for increased puncture resistance, and refined tread geometry for improved mud shedding and snow performance. The KO3 maintains all of the toughness that made the KO2 a benchmark while addressing real-world weaknesses.
Is the BFGoodrich KO3 33X12.50R15 rated for snow?Yes. The BFGoodrich KO3 in 33X12.50R15 carries the 3-Peak Mountain Snowflake (3PMSF) rating, confirming it meets federal standards for use in severe snow conditions. It is not a dedicated winter tire, but it performs significantly better in snow than standard all-season or summer tires.
What does Load Range C mean on the BFGoodrich 88627?Load Range C means the tire is constructed with 6 plies and is rated for higher load capacity than a standard passenger tire. Load Range C is appropriate for light trucks, SUVs, and off-road vehicles carrying moderate payloads or running with slight lifts that increase rotational stress.
What vehicles fit the 33X12.50R15 size?The 33X12.50R15 size is a popular fitment for first-generation Toyota Tacoma, Jeep Wrangler (TJ, YJ), older Ford Bronco, and other compact to mid-size trucks and SUVs with 15-inch wheels. Confirm your vehicle's minimum wheel width requirements and backspacing clearance before purchasing.
Does the BFGoodrich KO3 have raised white lettering?Yes. The BFGoodrich KO3 in 88627 features Raised White Lettering (RWL) on the sidewall. The letters can be mounted facing inward for a clean look or outward for the traditional off-road aesthetic.
What is CoreGard technology in the KO3?CoreGard is BFGoodrich's maximum sidewall technology, which adds a reinforced rubber layer to the sidewall compound to resist punctures and sidewall bruising from sharp rocks, curbs, and trail debris. This is one of the key improvements that distinguishes the KO3 generation from earlier All-Terrain T/A tires.
How does the KO3 perform on the highway?The BFGoodrich KO3 is engineered to balance off-road performance with acceptable highway manners. Road noise is moderate compared to maximum traction mud-terrain tires, and the improved tread compound versus the KO2 results in better wet highway braking. Highway tread wear is competitive for an all-terrain in this load range.
Installation Instructions
- Confirm wheel fitment: 15-inch wheel with 8.5-10.5 inch recommended rim width for the 33X12.50R15 size
- Mount and balance the BFGoodrich KO3 at a certified tire installation facility
- Torque wheel lugs to vehicle manufacturer specification after installation
- Inflate to the load-range C recommended pressure for your vehicle weight (refer to door jam sticker and BFGoodrich load chart)
- After the first 500 miles, recheck lug torque and tire pressure
- Rotate tires every 5,000 miles to even out wear across all four positions
BFGoodrich
BFGoodrich has spent decades winning the Baja 1000 and other endurance races to prove that its tire technology survives conditions that destroy ordinary tires. That motorsport heritage translates directly to the tires BFGoodrich sells for street trucks, off-road SUVs, and performance cars, giving everyday drivers access to compounds and tread designs refined under extreme competition conditions. Popular Upgrades The BFGoodrich All-Terrain T/A KO2 is one of the best-selling off-road tires ever made, offering a three-ply sidewall and aggressive siping that handles highway use, light mud, gravel, and snow while lasting well beyond most competitor all-terrain tires. The Mud-Terrain T/A KM3 steps up to maximum off-road aggression with deep lugs and self-cleaning tread for serious rock and mud terrain. The g-Force Comp-2 A/S brings BFGoodrich motorsport compound technology to a street performance tire with excellent wet and dry grip. How do I choose between the KO2 and the KM3? Choose the...
