Goodyear Wrangler SR-A vs BF Goodrich Ko2

The tires discussed here are All-Terrain(A/T) tires explicitly made to provide splendid performance on paved and off-road areas. Although both tires have a standard build, their tread design, groove pattern, and radial sizing enable them to perform differently in varying conditions.

Goodyear Wrangler SR-A is a balanced off-road tire to provide fantastic performance in rough terrains with confident traction on paved roads.

BFGoodrich KO2, on the other hand, comes with a more aggressive design to favor extreme off-road adventures and wild trails. Find more about the exciting features of these tires as we present a detailed comparison of these beasts to save your precious time and help you choose the right type of wheels for your vehicle.

General Quick Comparison

Goodyear Wrangler SR A



Wrangler SR-A has an innovative build design. The tire has four main longitudinal grooves that divide the tire into four sections. The central blocks are divided into small tread blocks to increase the void ratio. We can see efficiently placed advanced zig-zag sipes, deep cuts, and tapered edges inside each tread block. The central rib has a zig-zag cut design instead of a straight cut perpendicular to the grooves that can be seen on the side ribs. The tire is given a balanced shoulder design with minimal spacing to increase the contact patch for lateral stability. The shoulders have massive self-cleaning cuts that help to maintain the vehicle’s strength while cornering. The tire has a stone ejection feature, but it is not prominent and can favor mild rocky conditions.

Goodrich KO2 is a beast for off-road terrains as its design is specifically built to overcome rough surfaces and withstand extreme conditions.

The tread has an overall aggressive look, with a vast number of tread blocks covering the entire body of the tire. Unlike other tires, KO2 does not have a traditional tread design. Instead, it consists of small worm-like blocks spread irregularly over the entire tread. This innovative design significantly increases the void ratio of the tire. The tire has massive shoulder and bold sidewall lugs for lateral stability and an overall aggressive look. The spacing between the shoulders is comparatively high. The tire has impressive stone ejectors, which favors it in rough areas. Overall, the tire has all the features required for off-roading.

On-Road Traction

A tire with more contact patch will be more reliable and provide more grip and stability. The tread pattern of Wrangler SR-A makes it dominate on highways as its longitudinal tread design helps it to offer more contact patch and increase grip with the road. The void ratio in this tire is relatively low, which helps to attain maximum grip with the surface, therefore, reducing the braking distance. The wet traction of SR-A is also satisfactory as the efficient zig-zag sipes consistently wipe away the water from the tread to maintain the mobility of the tire in wet areas.

KO2 performs decently on paved roads, but due to a relatively higher void ratio, the tire lacks a bit in maintaining maximum grip with the road while going at high speeds. The reduced contact patch reduces the grip and handling of the tire, therefore increasing the braking distance and compromising the stability compared to its competitor. However, the efficiency of the tire is increased on wet roads as the 3D sipes technology efficiently cleans the tire and maintains mobility.

Off-Road Traction

Traction on Mud

For off-road performance, tires with broader spacing and high void ratio give a better performance regarding stability and handling. Wrangler SR-A has to struggle a bit if we talk about navigation through deep mud terrains due to its narrow grooves. The closely spaced tread blocks cannot handle extreme mud loads and may fill up with soft mud and dirt, leading to skidding of tires. The relatively narrow grooves cannot clear all the soft mud from the tire, which compromises the handling and grip of the vehicle. This tire can be used in mild rough areas, but it is recommended not to expose them to deep mud terrains it could get stuck and cause problems.

KO2 dominates in muddy swamps due to a greater number of grooves and higher void ratio. The spacing between the blocks is wide enough to maintain the smooth mobility of tires. They assist in throwing big chunks of mud backward, clearing the vehicle’s path, and maintaining a maximum grip on the muddy road. The bold shoulders help to provide maximum stability while turning, prevent mud from entering the spaces, and promote sidewall protection. The higher void ratio enables self-cleaning and allows smooth navigation through muddy roads without compromising the grip and handling of the vehicle.

Traction on Snow

Similarly, if we talk about snow, Groove spacing and void ratio are the prime factors to decide the vehicle’s performance. As Wrangler SR-A comes with a relatively less number of grooves with narrow spacing, it lacks a bit in extremely snowy conditions. When the tire passes through soft snow, it could enter the narrow tracks and fill up the tread, making it lose its traction with the road. The tread design of SR-A allows it to handle mild snowy conditions, but it might not perform adequately in extreme weather. Let’s talk about navigation on icy roads. It becomes more reliable as a higher contact patch and a zig-zag sipes pattern allow it to deliver maximum traction and maintain smooth mobility.

KO2 dominates over snow terrains again as the quirky tread design helps it to propagate smoothly through soft snow without much effort. The tread blocks are efficiently placed to scoop out the snow from wide grooves and maintain traction with the road. The bold shoulders increase their performance by biting off soft snow to improve the grip and maintain lateral stability while cornering. However, the tire’s efficiency is slightly reduced on ice as the contact patch is reduced with the surface.

Traction on Rocks

Wrangler SR-A is designed to give satisfactory performance in mild rocky terrains as it has provided a good contact patch to maintain its grip on the rough road. One thing to remember while exposing this tire to rocky terrains is that it has narrow spacing between its ribs along with comparatively lesser grooves due to which small stones could enter and get stuck between them. This could cause damage and make the tire vulnerable to stone drilling as its stone ejection feature is not dominant enough.

KO2 does not have to struggle much while propagating through rocky terrains. You can take this tire on wild adventures, and the results will not disappoint you. The peculiar design has many tread blocks that enable it to maintain a maximum grip on the rough surface without compromising its stability. The wider groove channels do not allow any stones to get stuck between them. Moreover, it has prominent stone ejectors that efficiently clean small rocks out of the tire.


Dynapro has an on-road-friendly tread design with minimal spacing and an increased contact patch. This increases the tire’s comfort significantly as more contact patch leads to less noise production and a smooth on-road drive.

KO2 has an aggressive tread design that compromises the tire’s comfort as more air enters the wide groove channels and creates a resonance that makes the tire a bit noisy on highways.

Durability and Treadwear

Wrangler SR-A is pretty durable and offer arounds 50,000 mileage, which is reasonably good.

KO2 is a tough tire with an aggressive design and is made with a robust compound that provides maximum protection from external damage to withstand extreme conditions. This tire also provides around 50,000 miles on rough and smooth areas combined.


Both the tires have fair prices according to their features. Comparing them side by side, KO2 is more expensive than SR-A due to its exceptional off-road capabilities. 


  • Both the tires are All-Terrain tires.
  • SR-A provides maximum traction on paved roads.
  • KO2 dominates in mud, snow, and rocky terrains due to its aggressive design and off-road capabilities.
  • SR-A is quieter on highways and offers a smooth and comfortable ride. 
  • KO2 is a bit expensive than SR-A due to its impressive off-road features with confident on-road performance.
