Nitto Terra Grappler G2 Vs BF Goodrich KO2 T/A

Share This Post

The BF Goodrich KO2 stands out as the top choice among all-terrain tires. You might wonder, with its premium cost, is it truly the best pick? Let’s compare it with a more wallet-friendly contender, the Nitto Terra Grappler G2. The latter has been upgraded and now boasts a 3PMSF (Three-Peak Mountain Snow Flake) rating, much like the KO2. It promises to be an excellent choice for trucks like the Ram 1500, Ford F-150, Chevrolet, and GMC Sierra. So, let’s dive in.

The Jeep Rubicon often sports the BF Goodrich KO2, a testament to its popularity.

Drawing from my experience as a tire engineer, I can say the BF Goodrich KO2 excels in off-road adventures. Its durability is unmatched, thanks to robust sidewall biters and a unique interlocking groove design. Meanwhile, the Nitto Terra Grappler G2 shines on highways, offering superior traction. However, it could perform better on wet roads. This is because its siping, while ideal for snow, is less effective in rainy conditions, despite its excellent severe winter rating.

Switching gears to the Nitto Terra Grappler G2, these tires bring their own unique offerings to the table. Available in sizes from 17 to 24 inches, they cater to a broad range of vehicles, including those requiring larger rims. Speed isn’t an issue, with speed ratings that include R, S, T, and H, ensuring that these tires can keep up with your vehicle’s capabilities.

The weight of these tires stretches from 30 to a hefty 80 pounds, and the tread depth varies too, from 12 to 17/32 inches, highlighting their adaptability to different driving conditions and preferences.

Durability

Off-road tires must be strong and resilient to handle tough terrain and sharp objects. The sidewalls are especially at risk of damage. Why? Typically, only a polyester casing protects this area, with the tire’s plies concentrated under the tread’s center.

However, the BF Goodrich KO2 stands out with its 3-ply polyester casing, reinforced with 2 steel belts and 2 spirally wound nylon cap plies. This triple-layered sidewall construction makes it one of the sturdiest A/T tires available.

In contrast, the Nitto Terra Grappler has a 2-ply build. Its durability is less impressive, partly because its nylon cap plies are not spirally wound, affecting both the sidewalls and the tire’s central region.

Tread Comparison

The Nitto Terra Grappler G2, a second-generation tire, boasts an enhanced tread pattern for superior performance on and off the road.

Nitto Terra Grappler G2

This tire features 5 ribs, creating 4 circumferential channels. The inner channels are narrower, while the outer ones include rugged block valleys with notches and stone ejectors. Look for stone ejectors linking the outer ribs, situated among the notches.

The central rib is broader, enhancing directional stability, and features chamfered edges and larger traction notches. All lugs share common traits, such as thick siping, though they’re not fully interlocking.

Towards the tire’s edges, the lugs form a pattern conducive to both on and off-road use. For off-road grip, it includes dual sidewalls and staggered shoulder lugs. Meanwhile, a secondary layer beneath the lugs boosts on-road lateral traction.

Conversely, the BF Goodrich KO2 presents a more aggressive tread design, indicating its readiness for more challenging environments.

BF Goodrich KO2

The middle section of the BF Goodrich KO2 tire features three main ribs, creating a neat and uniform design. Each rib comes equipped with full-depth siping, serving a dual purpose. Not only do these sipes enhance wet traction, but they also further divide the lugs, enhancing the tire’s ability to grip off-road surfaces effectively.

Moreover, each lug boasts traction notches, which further enhance the tire’s grip, especially on uneven terrains. Surrounding these lugs, at the outer edges, are triangular-shaped stone ejectors. These ejectors play a crucial role in keeping the tread area free of debris.

As we move to the tire’s shoulders, their design is noticeably aggressive. This aggressive design is key to the tire’s exceptional traction on rugged terrains. The shoulder lugs are spaced widely apart, featuring prominently placed stone ejectors.

Close to the inner edges, the lugs are marked by powerful full-depth notches. Meanwhile, on the outer edges, the lugs transition into traction scoops with a staggered design. This is complemented by thick sidewall lugs that connect the two distinct shoulder block shapes, further enhancing the tire’s durability and traction on challenging surfaces.

Off-Road Traction

Off-road tires need to be tough and smart to handle different kinds of ground. Let’s dive into how they do on some tough terrains, starting with the muddiest challenge.

On Mud

Mud demands tires that can keep themselves clean to stay grippy. While neither tire is perfect, the BF Goodrich KO2 stands out here. Its design includes middle ribs that lock together, acting as mud catchers. But, it’s the big spaces in its shoulders and the bold ejectors for stones that really help it stay clean. Deep notches cut through heavy mud, making it easier for the mud to get out. The tire’s side lugs and staggered shoulders act like mud scoops, helping the tire dig through and pull itself out.

The Nitto Terra Grappler, however, struggles with mud. Its side lugs are too close together, and the middle is quite closed off, making it easy for mud to stick and stay.

On Rocks

When it comes to rocky terrain, the BF Goodrich KO2 is a solid choice for all-terrain tires. It’s equipped with everything needed for rock crawling. It has notches and sipes in the middle ribs that help grip and chew on rocky surfaces, staggered shoulders for side traction, and strong sidewalls for extra protection. Deflating the tire a bit brings its three-ply sidewall lugs into play, offering exceptional grip and protection unmatched by other tires.

On the other hand, the Nitto Terra Grappler falls short on rocky terrain. It lacks effective sidewalls, has fewer gripping points, and misses the crucial sipes that help with traction, making it less effective in these conditions.

On Sand

Sand is a special kind of ground that needs tires with a big area touching the ground and special locks to keep the tire bead in place. This lets you let out some air for the best grip.

But, when it comes to sand, the BF Goodrich KO2 just doesn’t do as well as others.

Even though it’s lighter, its three layers of sidewalls and the nylon layers wrapped around make the edges really stiff. Plus, its sharp edges that grip well usually, end up digging into the sand too much.

And when you’re on sand, digging in is the last thing you want because it ruins the grip.

That’s where the Terra Grappler shines. It has smoother edges, which helps a lot.

It also tends to be wider, so it doesn’t press down as hard on the sides. This means it can move forward better on sand.

Highway Performance

When you’re cruising down the highway, a few key things make the drive smoother: how well your tires grip the road when it’s dry, how stable your ride feels, and how much control you feel like you’ve got over where the car is going.

Let’s dive into each of these aspects.

Dry Grip

Not all tires are great at holding onto the road, especially when it’s dry. All-terrain (A/T) tires can sometimes slip a bit because their rugged design isn’t always the best for hugging the pavement. However, some tires are made to stick to the road better, and the Nitto Terra Grappler is one of them. It’s so good that it can handle speeds up to H.

The most important part of the tire for gripping the road? The middle of the tread. This part presses down the hardest (thanks to how tires are shaped), making the grip here crucial. The Nitto Terra Grappler gets this right with a central rib that’s packed with wide blocks for a stronger road connection.

On the flip side, the BF Goodrich KO2 gives up a lot of potential grip to make room for grooves, making it less effective at sticking to the road.

Dry Handling

When it comes to handling, especially around corners, the tire’s edges come into play. As you turn, the weight of the tire leans on these edges.

Here, the BF Goodrich KO2 falls short again. Its spaced-out blocks can’t keep up a steady grip, wasting the energy from cornering on bending those blocks instead.

But the Nitto Terra Grappler stands out for its grip on turns. It links all its lugs together under a continuous rib, making sure the tire stays in touch with the road, giving you a steadier, more controlled ride.

Wet Traction

Wet performance splits into two main parts: wet traction and resistance to hydroplaning.

For all-terrain tires, beating hydroplaning isn’t usually the tough part. It’s getting a good grip that presents a challenge, thanks to the mix used in the tire and the way it’s treaded.

Let’s dive into both.

Wet Grip

What affects wet traction? Two things: how stiff the compound is and the density of the sipes.

Here’s the deal with sipes: they scoop up water, holding its tiny bits in their grooves. But they need to be flexible to pull this off well.

Unfortunately, these tires don’t excel here. Compared to others in their league, they lag behind in wet braking, handling speed, and side grip.

So, I have to mark these tires as below average. Yet, if we’re comparing, the BFG KO2 nudges ahead slightly, thanks to its greater sipe count.

The Terra Grappler? It’s not doing so hot. Its sipes are poorly designed, and its mix is too rigid, making it hard for water to flow out.

Hydroplaning

Hydroplaning, or aquaplaning, happens when a tire can’t get rid of water fast enough. The tire starts to skate over water, losing grip.

This explains the Nitto Terra Grappler’s weak performance in wet conditions.

Its shoulder blocks are tightly packed, blocking water from escaping as freely as it does with the BF Goodrich KO2, which boasts a network of grooves in every direction.

With more water stuck in the tire, the sipes have their work cut out for them, further reducing the tire’s grip.

Fuel Usage

All-terrain tires might not save as much fuel as other kinds of tires. However, this depends on your car, how you drive, and the roads you’re on.

If we keep everything else the same, the BF Goodrich KO2 shows better fuel use. It’s because this tire is lighter and its tread is more flexible. These two things mean it doesn’t resist rolling as much.

On the other hand, the Terra Grappler faces more resistance. Its asymmetric design isn’t as smooth, leading to higher rolling resistance.

Winter Capability

When we talk about how good a tire is in the snow, we look at three things: how well it stops, how it handles turns, and how it gets going in both light and heavy snow, plus on ice.

Even though both tires have good ratings for snow, the Nitto Terra G2 works better on lighter snow, while the BF Goodrich KO2 is the champ in deeper snow.

The trick with these tires is they try to catch and hold onto snow. That’s because tire-on-snow contact isn’t great for grip in winter. So, the Terra Grappler with its tight lugs can grab onto snow in lighter conditions. Meanwhile, the KO2 uses its interlocking ribs to hold onto softer snow in deeper areas.

Verdict

While the Nitto Terra Grappler stands out as a great choice for those on a budget, it does come with some limitations. These include aspects such as wet traction, fuel efficiency, tread life, and, notably, off-road capabilities.

Despite its shortcomings in off-road performance—which is somewhat expected when compared to the powerhouse BF Goodrich KO2—the Terra Grappler’s struggle with wet traction is particularly disappointing.

However, it’s worth mentioning that its sipes offer improved traction in winter conditions, earning the tire a 3-peak mountain snowflake rating, similar to the KO2.
