Choosing an all-terrain tire means deciding how much highway comfort you are willing to trade for tougher construction and better trail grip. The BFGoodrich All-Terrain T/A KO3 in LT285/70R17/E 126/123S is designed for truck and SUV owners who drive gravel, snow, dirt, and pavement in the same week. Its CoreGard sidewall protection, new all-terrain compound, and severe-snow rating make it a strong multipurpose choice. The tradeoff is a firmer, heavier E-rated setup that may be more tire than you need for mostly paved commuting.
Quick Verdict
Rating: 8.4/10, recommended with caveats
Best For: Trucks and SUVs that split time between highways, gravel roads, job sites, trails, and snowy conditions
Bottom Line: The KO3 combines durable sidewall protection, severe-snow capability, and a 50,000-mile limited treadwear warranty. It is less appealing when quiet highway manners, lighter steering, and maximum fuel efficiency matter more than off-road toughness.

What Is the BFGoodrich All-Terrain T/A KO3?
The All-Terrain T/A KO3 is BFGoodrich’s newer-generation all-terrain tire for drivers who need one set of tires to handle daily roads and rougher surfaces. This LT285/70R17 version fits a 17-inch wheel and carries a 126/123 load index with an S speed rating.
Its main selling point is balanced toughness. The tread compound and footprint are designed to wear evenly on gravel, while reinforced sidewall features help protect areas that are vulnerable to sticks, stones, and sharp trail edges. You also get an all-weather tread with a severe-snow rating rather than a basic mud-and-snow marking alone.
Who Should Buy It?
Best For
- You regularly drive gravel roads, construction sites, forest roads, or moderate trails.
- Your truck or SUV requires an LT285/70R17 E-rated tire with the correct load and speed ratings.
- You want year-round versatility and verified severe-snow traction in one all-terrain tire.
Skip If
- You drive almost entirely on pavement and place quietness, ride softness, and fuel economy first.
- Your vehicle calls for a lighter load range, a different speed rating, or a smaller overall tire diameter.
- You need maximum ice grip from a dedicated winter tire rather than all-terrain versatility.

What’s New on the BFGoodrich KO3?
The KO3 updates the well-known KO2 formula with a new tread pattern, a new all-terrain compound, and an optimized footprint. BFGoodrich also uses full-depth locking 3D sipes to maintain biting edges as the tread wears.
The practical goal is longer, more even wear on gravel without giving up the KO line’s off-road identity. Serrated shoulders and mud-phobic bars help the tread clear loose material, while the revised pattern supports steadier road manners than a dedicated mud-terrain tire.
Fit and Compatibility
LT285/70R17 identifies a light-truck tire that is 285 millimeters wide, has a sidewall height equal to 70 percent of its width, and fits a 17-inch wheel. Its overall size is substantially larger than many factory passenger-tire fitments, so matching the wheel diameter alone is not enough.
Check the tire size and load information on your vehicle’s door placard, then confirm approved wheel width, fender clearance, suspension clearance, and spare-tire space. A larger or heavier tire can change steering feel, braking response, speedometer accuracy, gearing, and fuel use.
Pro Tip: Before ordering a full set, compare the LT285/70R17 dimensions with your current tire and ask the installer to confirm load rating, wheel-width range, clearance at full steering lock, and spare-tire fit.
BFGoodrich KO3 Durability on Gravel
Gravel can chip tread blocks and accelerate wear, especially when a loaded truck travels quickly over sharp aggregate. The KO3 addresses this with an all-terrain compound developed for durability and an optimized contact footprint intended to spread load more evenly.
Full-depth locking 3D sipes help stabilize the tread blocks rather than leaving them unsupported. That design can improve wear consistency while retaining extra biting edges for loose and wet surfaces. No tire is puncture-proof, but these features make the KO3 better suited to repeated gravel use than a typical highway-terrain tire.
CoreGard Sidewall Protection
CoreGard Technology reinforces the sidewall area that often takes the hardest hits off-road. BFGoodrich pairs it with Advanced Deflection Design, which is shaped to help prevent protruding objects from snagging and splitting the sidewall.
| Feature | What It Does | Buyer Benefit |
|---|---|---|
| CoreGard Technology | Strengthens vulnerable sidewall areas | More protection on rocky or debris-covered routes |
| Advanced Deflection Design | Helps redirect sticks and stones | Lower risk of snagging and sidewall splitting |
| Load Range E construction | Supports demanding light-truck loads when correctly inflated | Better match for compatible work, towing, and overland setups |
The limitation is ride quality. E-rated construction can feel firmer than a lighter passenger or C-range tire, especially on an unloaded truck. Correct pressure matters because overinflation can make the ride harsher and reduce the useful contact patch.
BFGoodrich KO3 Traction in Mud and Snow
Serrated shoulders add biting edges near the outer tread, while mud-phobic bars help release packed material from the grooves. This combination is useful in loose dirt, shallow-to-moderate mud, slush, and rutted access roads where a highway tread can clog quickly.
The KO3 also carries the Three-Peak Mountain Snowflake symbol, meaning it meets a standardized severe-snow traction requirement. That makes it more winter-capable than an all-terrain tire marked only M+S. It still cannot match a dedicated winter tire’s specialized rubber and ice-focused design in the coldest, slickest conditions.
Highway Comfort and Road Noise
The KO3 is built to serve as a daily-use all-terrain tire, not a trail-only mud tire. Its optimized tread pattern should feel more stable and controlled on pavement than a highly open mud-terrain design, and the S speed rating supports normal highway use within legal and vehicle limits.
You should still expect more tread hum, weight, and rolling resistance than you would get from a highway-terrain or touring tire. Tire pressure, alignment, wheel balance, vehicle suspension, and tread wear can all affect noise and vibration, so proper installation is essential.
How It Performs in Real Use
Daily Highway Driving
For commuting and road trips, the KO3 offers the stability expected from a reinforced light-truck tire. It makes the most sense when your paved miles are mixed with rough roads, because a highway-focused tire will usually be quieter and softer if pavement is your only priority.
Gravel Roads and Job Sites
This is one of the KO3’s strongest use cases. The gravel-focused compound, tread-block support, and sidewall protection are designed for repeated exposure to sharp stones, loose aggregate, and debris.
Mud, Trails, and Overland Travel
The serrated shoulders and mud-phobic bars help maintain traction when the tread encounters loose or sticky material. It suits moderate trail use and overland travel, but deep mud may still favor a more aggressive mud-terrain tire.
Snow, Loads, and Towing
The severe-snow rating adds confidence for winter travel, and the E load range can suit compatible towing or payload applications. Your vehicle’s gross axle, payload, hitch, and towing limits remain the controlling numbers, and tire capacity does not increase those factory ratings.
Compatibility and Safety
Use the pressure specified by your vehicle manufacturer or a qualified tire professional for your actual load. The 80 PSI figure is the tire’s listed maximum pressure, not a universal daily setting. Check pressure when the tires are cold and never exceed the tire, wheel, or vehicle limits.
Install matching tires with adequate load and speed ratings on all required positions. Maintain correct alignment, balance, rotation, and tread depth. After changing to a larger tire size, verify clearance under steering and suspension movement, and confirm that driver-assistance systems and speed readings remain accurate.
Pros and Cons
Pros
- CoreGard Technology and Advanced Deflection Design improve sidewall protection.
- Gravel-focused compound and optimized footprint support durable, even wear.
- Three-Peak Mountain Snowflake rating adds verified severe-snow capability.
- Load Range E and 126/123 load index suit demanding compatible truck applications.
- 50,000-mile limited treadwear warranty adds long-term value.
Cons
- E-rated construction can feel firm and heavy on an unloaded daily driver.
- More road noise and rolling resistance than a highway-terrain tire are likely.
- The premium price is hard to justify when you rarely leave pavement.
Is It Worth the Price?
The KO3 sits in the premium all-terrain category. Its value comes from combining reinforced sidewall protection, severe-snow certification, load-carrying capability, and a 50,000-mile limited treadwear warranty in one tire.
It is worth considering when gravel durability and mixed-surface traction can prevent downtime or reduce the need for separate trail-oriented tires. It is not the best value for a lightly used SUV that stays on pavement, because a highway-terrain tire can cost less and provide a quieter, softer ride.

How It Compares to Alternatives
The BFGoodrich KO2 remains worth comparing where it is still available, especially when it costs less, but the KO3 is the newer design with updated tread wear, gravel durability, and snow-focused features. The Falken Wildpeak A/T4W is another all-weather all-terrain option for buyers comparing road comfort and winter capability.
The Nitto Ridge Grappler may appeal more when you want a more aggressive hybrid look and stronger emphasis on loose terrain. The KO3 makes the most sense when you want a balanced premium tire with established sidewall protection, severe-snow certification, and a mileage warranty.

Frequently Asked Questions
Is the KO3 suitable for daily highway driving?
Yes, it is designed for mixed on-road and off-road use. You should expect a firmer ride and more tread noise than a highway-terrain tire, especially with this E-rated size.
What vehicles fit LT285/70R17/E 126/123S tires?
This size is used on some full-size pickups, SUVs, and modified off-road builds with 17-inch wheels. Exact fit depends on the vehicle, wheel width, load requirement, suspension clearance, and approved tire diameter, so verify fitment before purchase.
Can the KO3 be used for towing heavy loads?
The E load range and 126/123 load index can suit demanding towing applications when the tire is properly sized and inflated. Your vehicle’s axle, payload, hitch, wheel, and towing ratings still set the safe limit.
What tire pressure should you run?
Start with the pressure specified by your vehicle manufacturer for the approved tire size and load, or use guidance from a qualified tire professional. Do not use the 80 PSI maximum as an automatic daily setting.
Is the KO3 a true winter tire?
It is an all-terrain, all-weather tire with the Three-Peak Mountain Snowflake rating, so it meets a severe-snow traction standard. A dedicated winter tire can still provide better ice grip and cold-weather braking in harsh climates.
How does the KO3 compare with the KO2?
The KO3 is the newer generation, with an updated compound, tread pattern, optimized footprint, and full-depth locking 3D sipes. It is designed to improve gravel durability, wear consistency, and snow traction while keeping the KO line’s sidewall toughness.
How often should you rotate the KO3?
Follow the rotation schedule in your vehicle manual and the tire warranty terms. Regular rotation, pressure checks, alignment, and balancing help the tread wear evenly and protect warranty eligibility.
What warranty comes with the KO3?
BFGoodrich lists a 50,000-mile limited treadwear warranty and a 60-day satisfaction guarantee for the KO3. The standard limited warranty covers qualifying defects for the original usable tread life or 6 years from purchase, whichever comes first, subject to the full terms.
The Bottom Line
The BFGoodrich All-Terrain T/A KO3 in LT285/70R17/E 126/123S is a strong choice when your compatible truck or SUV needs gravel durability, sidewall protection, snow capability, and daily-road usefulness from one tire. Skip it when your driving is almost entirely paved or when a lighter, quieter tire better matches your vehicle. Its main strength is durable mixed-terrain performance, while its main limitation is the firmer, heavier character of an E-rated all-terrain tire.
