BFGoodrich KM3 Vs Nitto Ridge Grappler (Updated 2023)

BFGoodrich KM3 Vs Nitto Ridge Grappler Which one is better? KM3 is a mud-terrain tire, while Nitto Ridge Grappler is an all-terrain tire designed to perform well on any terrain.

KM3 tires are known for their off-road ability, due to their wide grooves, no other tire can beat them on muddy terrain.

On the other hand, Grappler performs pretty well on the road, all thanks to its carefully designed unique pattern.

Have you ever wondered how Grappler is able to dampen sound even when moving at high speeds? Check out the comfort section!

The KM3 has an open tread design. There is an unusual gap between the shoulder lugs that is large in size. There are also bold and long stone emitters between the lugs. The shoulder lugs have a cut in between them.

The central part of the tire has small blocks arranged in pairs; between each pair runs a groove. The central blocks are surrounded by wide grooves and strong edgy stone ejectors are placed within the grooves.

Compared to its rival, Grappler has a closed pattern. There are two different shapes of shoulder blocks. Compared to the other grooves of the tire, the grooves between these blocks are wide. The stone ejectors are between the lugs, but they are not as bold as those on KM3.

In the center there are triangular blocks; every second block has a wide and deep cut. Blocks have sharp edges and are surrounded by narrower grooves. The entire tire is covered with Sipes.

Traveling on the road

When it comes to on-road performance, Grappler is the clear winner. Because of its compact tread design, more of the tire’s surface is in contact with the road, thus improving grip and traction.

When it comes to wet traction, Grappler again wins due to higher contact patch and frequent siping, sipes clear the water, and grip is improved. In addition, this tire has good hydroplaning resistance, although it isn’t quite as good as its competitor due to its narrower grooves, which aren’t able to throw water backwards efficiently, so chances of hydroplaning increase.

The KM3 is a mud terrain tire that should not be used on roads due to its open tread pattern and reduced contact patch. Due to this, it has poor grip on roads. The wet traction of this tire is also not good due to its small contact patch and lack of sipes. Though it isn’t good on road, its hydroplaning resistance is better than its competitor due to its wide grooves which allow water to easily pass through.

Mud Terrain

Muddy terrains are no problem for KM3. Due to its open tread design with wide grooves, when the tire comes across mud, all mud particles are easily passed through. Wide grooves throw mud in the opposite direction, clearing the path and helping the tire move forward.

When cornering, the tire is helped by the wide grooves between shoulder blocks as the mud gets passed by these grooves and the cornering gets smooth and easy with no chance of getting stuck.

Nitto Ridge Grappler has a closed tread pattern with narrow grooves, which hinders its performance on mud. There is a chance that the tire will get stuck in mud ponds because the narrow grooves cannot throw enough mud particles backwards.

However, this tire can be used in light mud areas without disappointing you, but if you go in deep and heavy mud then your vehicle may get stuck.

Snow Terrain

KM3 will not produce any different results from mud or soft snow. Thanks to its deep and wide grooves that grab and throw snow particles backwards, it will perform just as well in snow as it did in mud.

On ice, however, the opposite is true. Because KM3 has a small contact patch, the tire won’t grip on ice, and the Sipes are absent, so slipping is likely to increase, resulting in accidents.

The Ridge Grappler lacks grip in soft snow due to its narrower grooves and is unable to throw soft snow particles backwards, thereby reducing grip and resulting in tire getting stuck in deep snow. The high contact patch and frequent siping of this tire makes it perform better on ice than its opponent.

The high contact patch increases grip, while sipes wipe away water, preventing the tire from slipping or skidding. As a result, we can conclude that KM3 is the winner on soft snow, while Grappler is the winner on ice.

Rocky Terrain

For tires to have good traction on rocks or pebbles, they need wide grooves, biting edges, and frequent and bold stone ejectors. As discussed above, KM3 has wider grooves than its counterpart, as well as straight stone ejectors between the shoulders and triangular emitters in the middle.

Even though this tire does not have edgy blocks that hinder its biting ability, it still has wide grooves and ejectors to fill the gap. Stone ejectors prevent stones from getting caught in the grooves, and wide grooves aid in tire climbing.

Despite its narrow grooves, it has stone ejectors in between its shoulder lugs, although they are not as prominent as those on its counterpart.

Although it has edgy blocks, which are a plus point, the tire lacks sturdy ejection technology and wide grooves so it won’t perform as well as its counterpart. KM3 is the winner in the rocky/stone area because of a better pattern.

Durability of BFGoodrich KM3 Vs Nitto Ridge Grappler

KM3 has a smaller contact patch than its rival, therefore it has a lower rolling resistance. As a smaller portion of the tire is in contact with the road, treadwear will also decrease, resulting in a long tire life.

The tire is made with tough and long-lasting materials, and CoreGard Max Technology is also employed to construct it, as well as Krawl Tek compound, which makes it much more durable, and it comes with a six-year warranty.

The Ridge Grappler has a larger contact patch, so its rolling resistance is also higher. As more of the tread comes into contact with the ground, the tread compound wears down quicker, resulting in less tread life.

The material used to make this tire is durable and long-lasting. Due to its CoreGard Max Technology and lesser treadwear, KM3 is more durable.


The KM3’s on-road comfort is poor since it has wide grooves that allow air particles to get in between them. When air particles collide with tread block walls, noise is produced as the particles strike the walls.

Thus, the wide grooves of KM3 produce a lot of noise, especially when moving at high speeds. For off-road comfort, the KM3 performs very well as its wide grooves work as an extra suspension, so it feels like a lesser inflated tire, resulting in fewer jerks and a comfortable ride.

The Ridge Grappler tire produces very little noise because its narrow grooves allow less air particles to get stuck in between them, resulting in a more comfortable ride on the road.

The pattern of this tire is specially designed to dampen noise and provide peaceful and quiet highway rides. Off road, Grappler is not as comfortable as KM3 because it has narrower grooves and a higher contact patch, which makes the tire rigid and more jerks can be felt in the cabin.
