About this item
Product details
Legendary Toughness. Made Tougher. The Next Evolution of All-Terrain is Here. At BFGoodrich, we’ve won a lot of Baja races. But it’s the Baja races we’ve lost that push us forward. We took our toughest all-terrain tire ever and engineered it to be even tougher. So you can do it all. Legacies are Written in Dirt.
Engineered to Endure
We engineered the BFGoodrich All-Terrain T/A KO3 tire with a new tread pattern and new all-terrain tread compound to provide durability and longevity, even on gravel. Featuring an optimized footprint and full-depth locking 3D sipes, it’s designed for even wear over the long haul.
- OPTIMIZED FOOTPRINT SHAPE - Designed to evenly distribute stress, for long and uniform wear both on and off-road.
- NEW ALL-TERRAIN TREAD COMPOUND - Formulated to deliver longevity on-road and in grueling off-road conditions.
- FULL DEPTH LOCKING 3-D SIPES - Engineered to increase tread block stability, for even wear over the long haul.
Designed to Do it All
Even in the worst of conditions, the BFGoodrich All-Terrain T/A KO3 tire is made to grip. The serrated shoulder design and mud-phobic bars improve upon KO2 tire’s legendary mud and snow traction.
- UPDATED SERRATED SHOULDER DESIGN & MUD PHOBIC BARS - Engineered to improve mud and snow traction.
- INTERLOCKING TREAD ELEMENTS - Designed to maximize handling and traction on- and off-road by stabilizing the tread center and providing biting edges for off-road traction.
- SEVERE SNOW RATING - All new All-Terrain tread compound and full-depth 3D sipes allow the KO3 tire to be branded with the three-peak mountain snowflake symbol.
Built to Overcome
Our CoreGard Technology, developed for racing in Baja, gives the BFGoodrich All-Terrain T/A KO3 tire excellent sidewall toughness. And the Advanced Deflection Design helps prevent sticks and stones from snagging and splitting the sidewall.
CoreGard Technology
- RESISTANT SIDEWALL - Split & bruise-resistant sidewall rubber, derived from BFGoodrich’s race-proven Baja T/A® KR3 tire.
- ADVANCED DEFLECTION DESIGN - Advanced Deflection Design deflects protruding objects from snagging & splitting the sidewall.
- EXTENDED SHOULDER RUBBER PROTECTION - Extended shoulder rubber down the sidewall to protect more of the critical sidewall failure zone.
ALL-TERRAIN T/A KO3. The next evolution of all-terrain tires is here. Explore the all-new, all-tough BFGoodrich T/A KO3 tire and discover the freedom to do it all. WHEREVER YOU’RE GOING.

The Only Tire You wil Need!
I have using BFG All-Terrian Tires since the early 80's and they have never let me down. I have a 2015 GMC Sierra 1500 that came with the KO2 tires, I just replaced them after with the KO3 tires. The KO2 had 121,000 kms on them and their warranty was for 80,000 kms, I would only recommend BFG All-Terrian KO3 tires based on my 45 years of driving with them!
Amazing tires!
So far sooooo, great! I own a 4x4 Mercedes Benz Srinter 2500. I had a set of K03's installed before hunting season. Awesome all around traction in wet, snow and ice. I live in a remote area so I'm in 4x4 almost everyday. Not noisy on the highway either.
Smooth ride!
Very happy with these tires. Much quieter and smoother ride than the Nokian Rotiiva AT's that they replaced - it felt like I was floating down the road. In first 2 hours of driving on snowy and icy roads, traction was excellent and as a bonus, mileage improved from 18 l/100 km to 12 l/100 km!
