KM3 vs KO2 vs STT Pro: Detailed Analysis

KM3 vs KO2 vs STT Pro

Off-road performance

The winner: STT Pro

The KM3, KO2, and STT Pro are popular among off-roading enthusiasts. But we have discovered that the winner is the STT Pro.
One key factor that sets the STT Pro apart from its competitors is its aggressive tread pattern. This tire was designed for off-road use, featuring large, deep lugs that provide excellent traction in mud, rocks, and other challenging terrain. The STT Pro has a unique Armor-Tek3 construction that enhances puncture resistance and durability.

On-road performance

The winner: BFG KO2

On-road performance is an important factor to consider. Thanks to its outstanding Core-Gard technology and specially formulated tread rubber, the BFG KO2 remains unbeaten regarding on-road performance. These features allow the tire to provide exceptional directional abilities and steering feedback while ensuring extra highway grip and a smooth driving experience. Concerning wet roads, the BFG KO2 is still superior to its competitors, thanks to its hydroplaning resistance. The advanced grooves provide ample space for water to fill up, allowing drivers to maintain control and great traction even on wet surfaces.

Even though the BFG KM3 is primarily created for muddy terrain, it also delivers impressive highway performance. It offers excellent cornering stability and steering response, which is remarkable for an off-road tire. Compared to the BFG KO2, it falls short in wet traction. Since it is designed for off-road adventures, it lacks hydroplaning features essential for on-road tires.

Snow & Ice performance

The winner: BFG KO2

The BFG KO2 lives up to its all-terrain label by delivering remarkable performance on snow and ice. The three-peak mountain snowflake (3PMSF) emblem has been granted due to its proficiency in snowy and icy terrains. Moreover, the KO2’s resistance to hydroplaning provides drivers with exceptional grip on wet surfaces. The BFG KM3 and STT Pro, on the other hand, do not match the KO2’s traction on snowy or wet surfaces. Although the BFG KM3 is also engineered for extreme conditions, it falls short of surpassing the KO2 model in this category.

Noise level

The winner: BFG KO2 (Least Noise)

It is no surprise that the BFG KO2 ranks highest in noise levels. Being an all-terrain tire, its tread design has fewer gaps than the BFG KM3 and STT PRO, requiring more traction for off-road purposes. Consequently, the BFG KO2 provides a quiet and seamless driving experience.

The STT PRO is our poorest performer, producing unpleasant sounds while driving on roads, possibly because it was designed for off-road use. Nonetheless, the noise can be disregarded when necessary or with enjoyable music.

Comfort level

The winner: BFG KO2

BFG is a renowned brand that prioritizes driving comfort and relaxation. For this reason, the battle between their KO2 and KM3 model tires has been quite intense. Both models have unique features, but there can be only one winner.

After extensive tests and evaluations, the BFG KO2 emerges as the clear winner regarding overall performance and comfort level. The KO2 is an all-terrain tire that offers drivers excellent traction on mud, rock, snow, or sand surfaces. It’s highly durable with a tough sidewall design that ensures maximum strength to navigate rough terrains easily.

Moreover, its sipes (tiny slits in tires) significantly enhance grip on wet roads and reduce hydroplaning risks. On top of that, it also provides a smooth ride with minimal noise levels on highways so you can enjoy long trips comfortably without any fatigue or discomfort.

Treadwear Warranty

The winner: BFG KO2

The BFGoodrich All-Terrain T/A KO2 continues to dominate the off-road tire market thanks to its innovative Cord-Gard technology and specially produced tread rubber. This blend of materials enables the KO2 to easily tackle tough terrain, making it a popular choice among enthusiasts who demand performance and durability from their tires. These components make the KO2 a perfect fit for trucks, SUVs, and other off-road vehicles.

The winner of numerous industry awards, including Popular Mechanics’ Editor’s Choice Award in 2019, the BFG KO2 is one of the most sought-after tires on the market. Not only does it offer exceptional traction in both wet and dry conditions, but it also has an impressive treadwear warranty that ensures long-lasting performance.


The winner: BFG KO2

The BFG KO2, STT PRO, and KM3 are all popular off-road tires from BFGoodrich. The starting price of the KO2 is $190, making it the most affordable option among the three. The KO2 is an all-terrain tire providing excellent traction on and off-road.

The STT PRO has a starting price of $208. It is designed for extreme off-road conditions and features large tread blocks for maximum grip. The STT PRO also has sidewall protection to prevent rock and debris damage.

The KM3 has a slightly higher starting price of $212 but offers superior performance in mud and rocky terrains compared to the KO2 and STT PRO. Its advanced Krawl-TEK compound provides exceptional grip even on wet rocks, while its Terrain-Attack tread design delivers better handling in mud conditions.

Final Thoughts

Meanwhile, the STT Pro strikes a balance between both worlds. Ultimately, it comes down to individual preferences and driving habits when choosing between these three tires.
