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 manufactured to deliver good performance on and off the road.

AT2 provides better traction on road because of its lower void ratio and densely packed tread design, but KO2 performs better when off-roading due to its widely spaced tread design.

Comparing BF Goodrich KO2 and Toyo Open Country AT2

The aggressive tread design of the KO2 allows a lower area of tread to have contact with the road due to its higher void ratio which reduces the tire’s grip. Therefore, it causes insufficient on-road dry traction. Water is easily able to navigate through its broad grooves and deep sipes, allowing excellent wet traction, thus preventing hydroplaning.

Broader grooves are also responsible for removing the dirt & Soft snow efficiently from the tread. 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. Stone ejectors are implanted in the grooves to keep stones/pebbles out.

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 a tread block design that is aggressive and interlocked with a lower void ratio, allows for higher contact with the ground and improved on-road traction. It is designed with narrow 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 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

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

The lesser void ratio of AT2 provides for better traction since there is large surface contact within the tread and the ground. This improves grip and, the overall dry traction on road. In the rainy season, the narrower grooves and many sipes are ineffective because they can’t effectively wipe the water away, resulting in hydroplaning.

Off-road Traction Comparison

Mud Terrain

Due to its greater void ratio, KO2 can confidently grip the mud by efficiently pushing backward using its broad 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 backward, therefore, can’t provide the necessary grip on mud. If the tire is operated in deep muck, it will become stuck 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 rocky terrain. The tire has larger and more visible stone ejectors that enable 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 don’t allow a good grip on tricky angles of approach on rocks while cornering. These tires have smaller stone ejectors, 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 many harsh conditions.

Which tire has better Comfort?

While driving at high speeds on the road, the wider grooves of KO2 trap more air inside. This air after getting traped inside the grooves, moving back and forth against the wall, therefore it 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 a small quantity 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 to the ground, decreasing its rolling resistance. Low rolling resistance results in 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 the AT2 tire tread are narrow, therefore, it has a less void ratio. A lower void ratio results in a larger contact patch with the ground and hence more rolling resistance. Tires with greater rolling resistance will wear out faster, making them less durable and decreasing their 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 preferred on-road experience whereas KO2 allows better off-road performance.

Quick Summary

  • Both of these tires are All-terrain.
  • AT2 has better dry traction on road.
  • 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 durableness and tread wear resistance.
