The Open Country A/T III is the latest iteration in Toyo’s popular Open Country A/T line, building upon the previous generation with improvements to tread life, wet performance, ride comfort and off-road traction.

Toyo uses an asymmetric tread design on the A/T III, with larger, more aggressively designed outer tread blocks to provide added traction when navigating rough terrain.

Inside, smaller sipes help enhance grip on wet roads. The tires use Toyo’s proprietary Silica tread compound to balance long wear with grip across various road conditions.

Overall, the Open Country A/T III aims to deliver a durable, smooth and quiet on-road ride paired with capable off-road performance for truck and SUV owners seeking an all-terrain tire suited for everyday driving as well as weekend adventures.

All-Terrain Design

The Toyo Open Country A/T III is designed to provide both on-road comfort and off-road capability.

Unlike more aggressive mud-terrain tires, all-terrain tires like the Open Country A/T III strike a balance between on-road manners and off-road traction.

Toyo uses an all-season tread compound that aims to optimize wet weather performance and wear life, while still providing adequate traction for light to moderate off-roading.

The tread pattern combines independent blocks, zig-zag sipes, and ramped tread edges to maintain grip on varied surfaces.

For on-road driving, the tires feature a symmetric, non-directional tread pattern to minimize noise and vibrations.

The stiff tread blocks and sidewall construction also contribute to a smooth, comfortable ride quality on the highway.

In off-road conditions, the aggressive shoulder blocks and staggered intermediate tread blocks grip well in loose dirt, gravel, and mud.

The tire construction includes twin steel belts for puncture resistance when driving over rocks or debris.

Overall, the Open Country A/T III balances everyday comfort with weekend warrior abilities.

Drivers who spend most of their time on the road but still venture off-pavement on occasion will benefit from the all-terrain design.

Traction and Handling

The Toyo Open Country A/T III is an all-terrain tire designed to provide excellent traction and handling in various conditions.

The aggressive tread pattern and siping help to maintain grip on muddy trails, snowy roads, and wet pavement.

The large tread blocks have multiple edges that bite into loose surfaces like mud and snow. The tire cleans out well between the blocks to prevent packing.

Reviewers consistently praise the Open Country A/T III’s traction in mud, whether it’s thick and sticky or wet and slippery.

The tire claws through without slipping and spinning excessively.

For snow traction, this Toyo tire performs very well, even in deep snow. The aggressive tread blocks combined with ample siping along the blocks give it plenty of biting edges.

Testers found the A/T III gripped well accelerating on snowy roads without excessive wheel spin. It also provided secure braking without sliding.

On wet pavement, the siping and tread design provide solid wet traction and hydroplaning resistance.

The tire channels water effectively through the grooves so you maintain contact with the road. Handling in rainy conditions feels precise and predictable.

Overall, drivers praise the outstanding traction and grip of the Open Country A/T III in mud, snow, and on wet roads.

The tread design excels across various conditions for all-terrain performance.

Ride Quality of Toyo Open Country A/T III

The Open Country A/T III provides a very smooth and comfortable ride, even at highway speeds. The tire design helps minimize road noise and vibrations in the cabin.

Toyo uses a variable pitch tread block design that reduces harmonic noise on the highway.

The alternating tread blocks help break up noise patterns and vibrations. Owners report the Open Country A/T IIIs are much quieter than comparable all-terrain tires from other brands.

The tire’s sidewall is designed to absorb impacts from bumps and uneven pavement. This cushions the ride and reduces vibrations felt in the steering wheel or seats. The smooth ride contributes to the tire’s comfort for long road trips.

Overall, the Open Country A/T III delivers a very compliant and relaxed ride for an all-terrain tire.

Both noise and vibrations are very well muted, providing a premium ride experience on-road.

The smooth highway manners make it easy to forget you’re riding on aggressive all-terrain rubber.

Treadwear

The Toyo Open Country A/T III is designed for longevity and durability. Owners can expect a treadwear lifespan of 50,000 to 70,000 miles for P-Metric sizes, depending on driving conditions and habits.

The tire carries a 50,000 mile treadwear warranty, which is less than some competing all-terrain tires but still respectable.

The tread compound uses a blend of polymers intended to resist chipping and tearing on rough terrain while maintaining treadlife on the pavement.

Independent tests show the A/T III averaging a treadwear score of 560, which is lower than touring tires but on par with other off-road capable options.

Proper maintenance like rotations and inflation pressure can help maximize the lifespan.

Overall, the tire should provide adequate treadlife for a rugged all-terrain, though drivers focused purely on longevity may want to look at options with higher treadwear warranties.

The A/T III strikes a good balance between off-road traction and on-road endurance.

Off-Road Capabilities of Toyo Open Country A/T III

The Toyo Open Country A/T III performs very well off-road thanks to its rugged all-terrain tread design.

The aggressive tread pattern with large, staggered blocks provides plenty of bite for climbing over rocks and loose dirt.

On rocky trails, the Open Country A/T III maintains solid traction without excessive wheel slip.

The chunky tread blocks grip rocky surfaces while the sidewall lugs add lateral traction. The tire excels on dirt roads and trails, with the siped tread blocks biting into soft surfaces.

For sand driving, the Open Country A/T III is an excellent choice. The self-cleaning tread pattern prevents sand buildup.

The large tread voids allow the tire to sink in and gain traction on sandy terrain. At the same time, the staggered blocks provide straight-line stability in soft sand.

Overall, with its balanced tread design, the Toyo Open Country A/T III delivers strong performance across different off-road conditions from rocks to dirt to sand.

Drivers looking for an all-terrain tire capable on the trails will be satisfied with the traction and grip.

Wet Performance of Toyo Open Country A/T III

The Toyo Open Country A/T III performs very well in wet conditions thanks to its aggressive tread pattern and siping.

The large, interlocking tread blocks provide plenty of edges to bite into wet pavement and channel water away efficiently.

When braking in the wet, the A/T III stops shorter than many all-terrain tires. The ample tread depth and siping allow the tire to find grip and shed water when braking hard.

Hard braking in standing water is still ill-advised, but the A/T III performs better than expected for an all-terrain.

Hydroplaning resistance is also good for an all-terrain tire. The tread design prevents water from pooling up under the tire at highway speeds.

Only during severe storms or very heavy rain will the A/T III be at risk of hydroplaning.

In light rain and snow, the A/T III provides secure handling and traction. The siping and independent tread blocks give the tire the ability to find grip even when the road surface is wet.

In heavier snow, a dedicated winter tire would be better, but the A/T III can still power through and get you where you need to go.

Overall, the wet and snow performance exceeds expectations and makes the A/T III a very capable all-weather tire.

Pricing

The Toyo Open Country A/T III is competitively priced against other all-terrain tires. Price will vary based on tire size, but here are some examples:

• 235/75R15 – $150 – $180 per tire
• 265/70R17 – $180 – $220 per tire
• 285/70R17 – $200 – $250 per tire
• 305/55R20 – $250 – $300 per tire

In general, expect to pay between $150 and $300 per tire. Larger tire sizes for trucks and SUVs fall on the higher end of that range.

Smaller sizes for compact SUVs and crossovers are more affordable.

Overall, the Toyo Open Country A/T III offers a good balance of off-road capability and on-road comfort at a reasonable price point.

While not the cheapest all-terrain tire, it delivers performance that justifies the cost for most drivers.
