BF Goodrich KO2 vs Toyo Open Country AT2

Both the BFGoodrich KO2 and the Toyo Open Country AT2 are All-Terrain (A/T) tires that are designed to deliver a balanced performance on and off the road. AT2 provides better on-road traction because of its lower void ratio and the densely packed tread design, but KO2 performs better while off-roading due to its widely spaced tread design.

Comparing BFG KO2 with Toyo AT2



Toyo AT2

The aggressive tread design of the KO2 allows a lower contact area of tread in contact with the ground due to its higher void ratio which reduces the tire’s grip. Therefore, resulting in poor on-road dry traction. Water can easily pass through its broad grooves and deep sipes, allowing excellent wet traction, hence preventing hydroplaning. Wider grooves are also responsible for removing the dirt and soft snow through the tread efficiently. The ‘Serrated Shoulder Design’ makes it easier to handle mud, sand, or even snowy terrain. But, when it comes to ice, the KO2 lacks in providing decent grip due to lower contact patch and shallow sipes. The stone ejectors are embedded to keep stones/pebbles out of the grooves. The ‘CoreGard’ technology has been installed on the sidewalls of the tires for additional protection. In addition to shoulder protection, this technology also protects the sidewall from excessive pressure. Any sharp items, pebbles, or trash may readily be deflected by the walls. The KO2 tire’s unique footprint design allows the vehicle’s entire weight to be distributed evenly.

The AT2 also has an aggressive interlocking tread block design with a lower void ratio, allowing for a higher contact patch with the road and improved on-road traction. It is designed with narrow tread grooves and zig-zag sipes which provides average traction on wet surfaces. Because of the narrow grooves, it has limited mud, soft snow, and gravel traction. The large stone ejectors ensure safe travel on rocky terrain by preventing stones from being caught in the grooves. Due to its larger contact patch and zig-zag sipes, the particular tire’s grip on icy roads is also impressive. It has an excellent build quality and a long tread life. The major benefit of this tire is that it is extremely quiet on the road while moving at high speeds. So, if you’re driving on-road, the Toyo Open Country AT2 would provide a great experience.

On-Road Traction Comparison

The KO2 has a higher void ratio, due to which there is less contact between the tread and the road, resulting in lower grip. This allows lower traction on-road. Wide grooves and many deep sipes easily pass water through them, avoiding the hydroplaning and providing excellent wet traction.

The lower void ratio of AT2 provides for better traction since there is more contact between the tread and the ground. This improves grip and, the overall dry on-road traction. In rainy season, the narrow grooves and shallow sipes are ineffective because they can’t effectively wipe the water away, resulting in hydroplaning.

Off-road Traction Comparison

Mud Terrain

Due of its higher void ratio, KO2 can confidently grip the mud by efficiently throwing it backwards using its wide grooves. The open shoulders also allow the mud to easily pass through them. The mud traction of the KO2 is superior because of these characteristics.

The AT2 has narrow grooves due to which it can’t effectively evacuate the mud backwards, therefore, can’t provide necessary grip on mud. The tire will become stuck if it is used in deep mud because the grooves will be filled with mud, turning the tire into a slick.

Snow Terrain

The large grooves of the KO2 provide easier travel in soft snow since it can be efficiently thrown backward, but traction on icy roads is poor due to the lower contact patch of the tread. Although, the tire is rated as a three-peak mountain snowflake (3PMSF), it is still ineffective in hard snow.

The AT2, on the other hand, has narrow grooves that are comparatively ineffective at throwing back the soft snow, making it difficult to retain the necessary traction. However, since it has a large contact patch and a high number of sipes, that are useful in maintaining traction on an icy road. It is also categorized as a three-peak mountain snowflake (3PMSF) tire.

Rock Terrain

The higher void ratio of KO2 allows enhanced grip during tricky angles of approach on rock terrain. The tire has larger and more visible stone ejectors that enables it to prevent any stone or pebble from getting stuck inside its grooves. Due to these characteristics, the KO2 is more capable to handle rocky terrain than the AT2.

The AT3 tire has narrow grooves that doesn’t allow good grip on tricky angles of approach on rocks while cornering. These tires have smaller stone ejectors, and which cant effectively stop the stones from getting trapped inside the grooves. As a result, using this tire on rocky terrain is not preferred especially in too much harsh conditions.

Which tire has better Comfort?

The wider grooves of the KO2 trap more air inside while traveling at high speeds on the road. This air after getting confined inside the grooves, strikes back and forth against the wall, therefore, producing higher noise. This noise reduces the tire’s overall comfort.

The comfort level of the Toyo open country AT2 is vastly higher due to its narrow grooves. Since, narrow grooves allow lesser amount of air to get trapped inside them, producing less noise.

Durability and Treadwear Differences

Wider grooves of the KO2, allow more tread blocks to contact with the ground, decreasing its rolling resistance. Lower rolling resistance means less treadwear because of less contact with the surface, which means it will last longer than its counterpart. The tread blocks are made of a high-wear-resistant compound that is then molded into an aggressive, computer-optimized interconnected tread block pattern with a high void ratio to boost durability for both on and off-road traction.

The grooves in AT2 tire tread are narrow, therefore, it has a lower void ratio. A lower void ratio results in a larger contact patch with the ground and hence more rolling resistance. Tires with higher rolling resistance will wear out faster, making them less durable and decreasing its mileage as well.

Price Differences

Due to the better off-road performance, as well as their great durability and build quality, KO2 tire is costlier than AT2 tire. AT2 is primarily concerned with providing its consumers with a better on-road experience whereas KO2 allows better off-road performance.

Quick Summary

  • Both tires are All-terrain.
  • AT2 has better on-road dry traction.
  • In the mud and rocky terrain, the KO2 provides much better traction.
  • KO2’s performance is better in snowy conditions due to wider grooves.
  • AT2 performs better on ice due to the larger contact patch.
  • AT2 is more comfortable as it counters noise problems more effectively.
  • KO2 has better overall durability and tread wear resistance.
