Toyo Open Country AT3 vs Nitto Terra Grappler

The AT tires are off-road tires designed to provide traction in rough terrain while still providing decent street performance. These tires have a reasonably large footprint due to their off-road design, which means they will be evident in the vehicle they are mounted on.

Here we have picked Nitto Terra Grappler G2 and Toyo Open Country AT3 to compare their features give you complete reviews.

Comparing Toyo AT3 with Nitto Terra Grappler

The Nitto Terra Grappler G2 is an all-terrain tire that has a fairly aggressive tread pattern.

These tires have a reasonably high profile, making them look a little less sleek on the vehicles they are mounted on.

The Nitto Terra Grappler G2 is an all-terrain tire designed with on/ off-road and muddy driving conditions in mind. The tread pattern features an aggressive design with deep sipes and three large grooves, which increase the tire’s traction in both on-road and off-road conditions.

The shoulders feature a unique tread pattern to reduce friction on the tire shoulders while increasing traction in wet and muddy terrain.

Another feature of the Nitto Terra Grappler G2 is the “Coupling joints” in the tread that prevent uneven wear.

The tire also features a “Variable pitch tread design,” which creates a quiet ride thanks to its unique sipe positioning that minimizes vibration.

The Toyo Open Country is an all-terrain tire made for a variety of driving conditions. It has a unique s-shaped tread pattern to ensure optimal grip in both on-road and off-road conditions.

By now, you might be noticing a trend with these two tires.

They both have aggressive tread patterns designed for better traction in off-road applications, but they sacrifice some style for this added functionality.

If you are looking to put these tires on a larger truck or SUV, you may decide to go for the Nitto Terra Grappler G2, as it will not look out of place on this type of vehicle.

Dry Traction Comparison

Open Country AT III features increased block rigidity and a specially designed optimized pattern to enhance dry traction, handling and reduce braking distance. 

The open country has a more evenly distributed void area that increases the tread’s rigidity for exceptional handling.

Terra Grappler, on the other hand, features reinforced coupling joints to increase block rigidity for better handling, control, and performance on dry terrain. 

Comparing Off-Road Performance

As we mentioned earlier, traction and off-road performance are the two most crucial attributes of an A/T tire.

Both Toyo and Nitto have addressed these issues enough that either of these can make your adventure worth your while.

Open country ATIII features staggered shoulder lugs to enhance off-road performance, whereas the evenly distributed void area maintains its shape under off-road conditions and speed.

The S-shape tread compound allows open country ATIII excellent off-road grip.

In comparison to open country, Terra Grappler G2 has the lead. It provides you with both on-road and off-road traction. thus providing you excellent traction and handling on rough surfaces without losing its rigidity. 

Wet Traction and Hydroplaning Resistance

Being an AT tire means that a tire has to cope with weather and road conditions. The open country features 3D multi-wave sipes; these sipes are deeper than an average A/T tire. It allows ATIII excellent wet traction. G2, on the other hand, has full-depth sipes, which maintain its wet handling and aquaplaning. 

The open country features lateral grooves that aid in hydroplane resistance by quickly evacuating water and debris from within the tread. As per Nitto’s claims, the full depth sipes maintain the wet traction even after setting in of treadwear, but we observed a downfall in wet performance as the treadwear hit 20,0000 miles.

Snow Traction

Snow traction and handling are always a challenge for A/T tires. ATIII features 3D Multi-wave sipes for exceptional snow and ice performance. In contrast, Terra Grappler, on the other hand, features a Staggered shoulder design which helps in providing the biting edges necessary to cope with snowy or icy conditions.

Compared to G2, ATIII has the lead as it is 3MPSF awarded, which means that it has been passed through a series of rigorous tests and G2 hasn’t.

Ride Comfort and Noise Reduction

It’s no secret that A/t tires compromise on comfort and noise in return for excellent performance.

Terra grappler G2 features a variable pitch tread block that does the job in noise reduction and smooth ride. Open country ATIII, on the contrary, features a new tread compound that delivers a quiet ride. The S-shaped tread pattern of ATIII provides an increased contact patch, thus ensuring a smooth ride. 

When compared in terms of noise reduction and comfort, we observed Terra Grappler G2 to be better than Toyo Open Country ATIII.

Durability & Treadwear Comparison

With the course action expected from an A/T tire, one would assume these last shorter than other families of tires, and it couldn’t be farther from the truth.

Toyo features a more evenly distributed void area that maintains the tire rigidity, preventing its shape. ATIII is made of a unique all-season cut and chip resistant tread compound that will keep you rolling for years. Open country AT III has a durable two-ply polyester casing covered by twin steel belts for strength. The stone ejectors help remove any stones or objects stuck in the tread to avoid any punctures and abrasions.

On the other hand, G2 maintains its all-terrain adaptability while also providing excellent durability.  G2 has a link joint that joins the inner and outer treads, increasing its strength and allowing to maintain the shape while off-roading and during high-speed driving.

The full depth sipes help in maintaining the water evacuation abilities even after the tread wear has set in. 

Nitto claims that Terra Grappler G2 provides the same wet performance with its full-depth sipes even after setting in of treadwear, but we beg to differ. We observed a loss in wet performance after 20,000 miles. 

Open country AT III comes with a treadwear warranty of 65,000 miles on P/Euro-Metric sizes and 50,000 miles on LT and Flotation sizes. Toyo also offers a 45-day or 500 miles trial period. Terra grapple G2, on the other hand, is one of the first A/T tires by Nitto that offers a treadwear warranty. 

So which tire is better?

We compared both tires based on their tread and performance, and we also tested these tires are per our standards, and we concluded the following aspects:

  • In terms of dry traction, we observed terra Grappler G2 be in the lead as it had a shorter braking distance better handling.
  • Open Country ATIII had the edge in terms of wet traction and hydroplaning. G2 suffered from a loss of wet traction to a certain degree as the treadwear set in.
  • We found G2 to be more sophisticated on the road in terms of noise reduction and comfort.
  • Both G2 and AT III were tied in treadwear; both Nitto and Toyo back their respective tires with excellent warranties.
