What is the primary benefit of the BFGoodrich All Terrain T/A KO3 tire?

The All Terrain T/A KO3 is designed to offer a significant improvement in off-road traction and durability compared to standard highway tires. It features an updated tread pattern for better grip on loose surfaces and reinforced sidewalls to resist damage on trails.

Will these 37-inch tires fit my truck without modifications?

Fitting 37-inch tires often requires suspension modifications, fender trimming, or specific wheel offsets to prevent rubbing, especially during articulation or when turning. It is essential to verify your vehicle's clearance and consult with a professional if you are unsure.

How does the KO3 compare to previous All Terrain T/A KO models?

The KO3 is an updated version that BFGoodrich has engineered with a more aggressive tread design for enhanced grip and improved tread life. The sidewall construction has also been strengthened to offer better resistance to punctures and trail hazards.

Product Details

This is the BFGoodrich All Terrain T/A KO3 tire, sized 37x12.50R17 with a Load Range F and a 128R speed rating. It’s built for trucks and SUVs that see a lot of varied terrain, from pavement to trails. The KO3 is the latest update to BFGoodrich's well-known all-terrain line, aiming to give you more capability and durability where the road ends.

BFGoodrich has updated the tread pattern and construction for this KO3 version. You'll find a more aggressive tread design that helps with grip in loose conditions like mud and gravel, while still maintaining good road manners. The sidewalls are beefed up to resist punctures and damage from trail hazards, which is crucial when you're airing down for off-road adventures. They've also worked on improving tread life compared to previous versions, so you can expect more miles out of these tires before needing a replacement. The 37-inch size is a popular choice for those looking to significantly increase their vehicle's ground clearance and off-road stance.

When you're fitting tires this large, make sure your vehicle's suspension and fenders can accommodate them, and that your wheels are rated for this size and load. It's also a good idea to check your vehicle's gearing and speedometer calibration after installing larger tires. These tires are designed to be a solid performer across a wide range of conditions, offering a good balance for daily driving and weekend exploration.
