Cooper STT Pro vs BFG KM3 vs KO2

In a side-by-side comparison, let’s take a closer look at these three popular models:


This tire has aggressive tread patterns and durable construction to ensure enhanced traction in challenging terrains. KM3 has good self-cleaning properties that prevent mud and debris build-up. BFG KM3 has advanced Krawl-TEK compound.

This specially engineered rubber compound provides excellent grip on rocks, dirt, and other slippery surfaces. 


The BFG K02 tire has big tread blocks that grip well in mud, snow, and rocky areas and help keep itself clean. Its tough sidewalls are shielded by a strong rubber called Duraguard, which helps prevent punctures and damage during off-road trips. The tire is strong and can carry heavy loads, making it good for tough jobs.

Cooper STT Pro

The Cooper Discoverer STT Pro tire is built with Armor-Tek3 construction, with a three-ply sidewall technology for protection against cuts, punctures, and abrasions. Stone ejector ribs help keep rocks and debris out of the tire’s grooves and improve stability on rough surfaces.

The tires also have an advanced silica compound for better wet traction and grip on slippery surfaces. The innovative Armor Tek3 carcass construction adds an extra layer of protection against punctures for durability.

Now, let’s move on to the detailed analysis of KO2 vs KM3 vs STT Pro

KM3 vs KO2 vs STT Pro

STT PRO, The Winner

STT PRO is a tremendous mud-terrain tire that is good at handling off-road adventures. It has a firm grip and can handle tough mud better than other tires. This is because of its unique Armor-Tek 3 Carcass Protection technology, which protects it from damage on rough terrain.

The tire’s cleats also help it grip and move quickly in challenging off-road conditions. STT PRO is the best choice for unpredictable terrains.


Regarding off-road performance, the BFGoodrich KM3 is a strong contender, just trailing behind the STT PRO. Like its competitor, the KM3 is designed as a mud-terrain tire and boasts deep grooves that facilitate easy mud removal and prevent tires from getting stuck in challenging terrains.

While the BFGoodrich KO2 may not offer the same level of solidity as its rivals, it still holds its ground with competitive strength. 


One area where the KO2 shines is its smooth acceleration and ability to navigate corners effortlessly, making it an attractive option for off-roading enthusiasts. While KM3 and KO2 have their strengths, the STT PRO emerges as the clear winner regarding off-road performance. 

KM3 vs KO2 vs STT Pro

BFG KO2, The Winner

The BFG KO2 tire is unbeatable for on-road performance. It’s thanks to two things: the BFG KO2 Core-Gard technology and unique tread rubber. These work together to give excellent steering and control. Core-Gard protects against road hazards and is especially good on wet roads.

It resists hydroplaning by quickly getting rid of water so that you can stay in control even in long, wet drives.


The BFG KM3, in terms of wet traction, provides provisions for hydroplaning, which is crucial for on-road tires. At the same time, both the BFG STT PRO and BFG KM3 need to catch up in navigating on-road conditions.


The BFG STT PRO needs to be better for driving on paved roads. It’s designed for off-roading, so it has less traction and stability on pavement. The BFG KO2 has excellent traction on wet roads because of its unique design and technology.

It performs well on wet roads, making it a good choice for driving on pavement.

STT Pro vs KM3 vs KO2

The BFG KO2 tire has proven to deliver impressive performance on snow and ice, making it an excellent choice for drivers who frequently encounter winter weather conditions. Its exceptional abilities in snowy and icy areas have even earned it the prestigious three-peak mountain snowflake (3PMSF) symbol.

This symbol serves as a strong endorsement of the KO2’s reliability and effectiveness in these challenging environments. The KO2 boasts outstanding wet traction due to its advanced hydroplaning resistance capabilities.

This means drivers can rely on this tire to maintain grip even in wet conditions, further enhancing their safety and confidence on the road.

The BFG KO2 stands out as the tire with the lowest noise levels. Compared to its off-road counterparts, the KM3 and STT PRO, the KO2 is designed with fewer spaces in its tire patterns. This characteristic allows it to prioritize a smooth, quiet driving experience over excessive off-road grip.

Whereas the STT PRO performs poorly in noise production during on-road journeys. Its specific construction may be responsible for emitting unpleasant noises while driving on regular roads.

BFG’s KO2 and KM3 tires compete to provide the best driving comfort and relaxation. The KM3 has a tread design and big grooves that reduce friction for smoother off-road trips. The KO2 has slightly better traction.

Both tires promise a smooth ride with minimal noise, giving drivers a satisfying experience.

The BFG KO2 emerges again as the ultimate choice for a long-lasting and durable tire with a warranty covering up to 50,000 miles. At the same time, both the STT PRO and BFG KM3 face significant challenges regarding treadwear.

Although the KM3 boasts thick sidewalls designed for navigating rugged terrains, its trims are unfortunately too soft and susceptible to wearing off quickly. This compromises their overall durability in comparison to the KO2.

If we talk about cost-effectiveness, BFG KO2 stands out. With a starting price of $190, it offers excellent value for its durability. Unlike the BFG KM3 and STT PRO, the KO2 is more stable and less prone to wearing out quickly.

The STT PRO has a higher starting price of $208, while the BFG KM3 starts at $212. This makes the KO2 cheaper and a better choice for those seeking versatility in their tire investment.

When comparing the KM3 vs KO2 vs STT Pro, it is evident that the BFG KO2 dominates as an overall top performer. Whether you prioritize on-road trips or require reliable traction in snowy conditions, this tire easily surpasses the KM3 and STT Pro models.

Considering other crucial factors like comfort, treadwear warranty, and price competitiveness only solidifies its position as the superior choice. 

What Are The Problems With Tires k02 Vs KM3?

The K02 tire might have trouble due to its simple tread pattern and shallow treads. The KM3 tire could be noisier on the road and use more fuel than the K02, and its rugged tread design might wear out faster and be less comfortable on paved roads.

How Long Do KO2 Tires Last?

KO2 tires can last between 50,000 and 70,000 miles, depending on how you drive, the condition of the roads, and how well you take care of them. Rotating them regularly and looking after them correctly can make them last even longer.
