Both are all season tires made to perform in extreme winters as well as hot summers. Each tire has its own qualities depending on tread design.
Although ATX has higher tread depth, it is still not able to defeat KO2 on different terrains. We studied those terrains down in the off road section.

Tread Pattern of KO2 is balanced. Its grooves are wide but not too wide and the size of tread blocks is also normal. The shoulders have two types of tread blocks, although they are almost similar in shape but one is larger than the other. The tread blocks in central part are hooked shaped with round corners and are placed in three rows. Sipes are placed all over the tread. Bold stone ejectors are placed between shoulder lugs and triangular shaped emitters are placed in the central part.
This tire has a closed pattern with deep grooves. All the shoulder blocks are broad and are of similar shape. Central part has tread blocks placed in the order of three rows. Sipes are placed all over the tread. This tire does not have any stone ejectors in the central part, they are only present between the shoulder lugs. The ejectors are also not much bold and long.
Comparatively ATX wins if we talk about on road dry traction this is due to its larger footprint. It has higher contact patch that allows it to have higher grip while moving on dry roads. Its shoulders are also compact compared with its rival so they provide more confident experience while cornering on dry surfaces. Talking about wet grip this tire wins again due to its higher contact patch and frequent sipes. The sipes are deep which help to wipe away the water from tire’s tread. Wet handling of this tire is also commendable due to higher contact patch from shoulders side plus the presence of long sipes on shoulder lugs. This tire is good at resisting hydroplaning but due to comparatively narrower grooves it isn’t able to beat its counterpart in this aspect.
KO2 also performs well on the road. Its dry traction is better than many tires but it can’t beat its counterpart as its contact patch is less due to wide grooves. Which hinders its grip and as a result its dry braking distance is more than its competitor. Its dry handling can also not beat ATX as its shoulder have wide grooves placed between them. So, the contact patch from shoulders is reduced and handling is affected. The wet traction of KO2 is also good compared with many tires of its line but it isn’t able to beat its counterpart as its contact patch is less, both from the central part and from shoulders, moreover its sipes are also less compared with ATX. KO2 can resist hydroplaning better than its competitor as it has higher void ratio. Water has enough volume available to move, and the contact of tire’s tread is maintained with the road, even at higher speeds.
Off-Road Traction Comparison
As KO2 has wider grooves so it wins in this section. Basically, the mud particles need wide and interconnected grooves, so the tread can grab particles in the grooves and as the tire accelerates, they can be thrown backwards. As KO2 has wider lateral and longitudinal grooves so this tire provides more area for the evacuation of mud particles and as the tire moves the mud is thrown backwards.
ATX can also perform well on muddy terrains but it can’t beat KO2. ATX has narrower grooves comparatively so less particles can be grabbed in the tread as a result less mud is thrown backwards. It also has narrower lateral grooves so there is chance that these grooves will get stuffed with the mud and tire will lose grip, and as a result the vehicle will get stuck. It is recommended not to take this tire in deep mud but it will work well in the areas with thin mud.
Snow terrain is same as mud terrain it also demands wide grooves. The wider grooves will grab more particles of soft snow and they will be easily thrown backwards. As KO2 has wide grooves so it won’t be a problem for this tire to move in soft snow. Plus, due to wide grooves it has more biting edges that bite the snow efficiently and improve the grip of the tire. its handling will also be good due to much spaces in its shoulder blocks. While cornering snow will be easily able to pass through these spaces. On ice this tire can’t beat ATX as it has lower contact patch and less sipes. So, it won’t be able to grip efficiently and can slip as well.
ATX performs well in soft snow due to its deep grooves but it isn’t able to beat its competitor. The reason is again its lower void ratio, due to lower void ratio it is not able to grab more snow particles and it also has fewer biting edges which result in low grip comparatively. ATX has good snow traction but compared with KO2, it lacks behind. On icy roads, this tire has better grip than its counterpart. This is because of its bigger footprint and frequent siping. Sipes wipe away the water from ice while maintain the contact of tire’s tread with the ground.
At rocky terrain, KO2 performs really well. This is all due to its higher void ratio and bold stone ejectors. The higher void ratio results in better biting ability of tire and helps the tire to crawl. While stone ejectors that are placed all over the tread, stop any kind of rock/ pebble particle from getting stuck into the grooves. They save the tread from getting damaged and also make sure that tire moves smoothly.
On the other hand, ATX has a comparatively lower void ratio so its biting ability is limited plus it also does not have any ejectors placed in the central part and few ejectors are only placed in the shoulders, they are very thin as well. So as a result, the performance of this tire in rocky terrain is affected, but it can perform well on pebbles.
The on-road comfort is judged by the sound production of any tire. The more the void ratio more sound is produced due to the movement of air particles. As KO2 has higher void ratio so it produces more sound while moving on highways and its counterpart produces less noise due to narrower grooves.
Off road comfort of KO2 is more as it has lower foot print. Its wide grooves give the feel of a lesser inflated tire and much effect of jerks is absorbed by the tire. Comparatively ATX is not much comfortable off road due to narrower grooves but as it has good tread depth so it also absorbs the effect of jerks and provides a comfier ride.
Durability and Treadwear
Both are made with durable material. Both the tires have same workmanship warranty, of 6 years. ATX has many plus points such as longer Treadwear warranty and higher tread depth. Higher tread depth means longer tread life as tread will take more time to level with the grooves compared with KO2.
