This is a dependable all-terrain tire built to perform across various conditions during warmer months. It’s engineered for drivers of light trucks and SUVs who demand versatility, durability, and confident handling both on and off the pavement. Let’s dive into the technical specifications and features that make this tire a strong contender for your vehicle.

The Toyo Open Country AT Plus stands out with its robust, asymmetrical 5-channel tread profile, promising an extended service life. Its solid construction not only delivers impressive grip on dry roads but also enhances traction when you venture off the beaten path. Whether your journey takes you down the highway or onto rugged trails, this tire’s block design is ready for action.

Toyo promises stable and smooth handling on uneven ground, a testament to the tire’s solid construction. The reinforced sidewall area provides crucial protection against sharp stones and potential damage, ensuring that spontaneous off-road excursions are never an obstacle.

The Toyo Open Country AT Plus 255/65R16 109 H is speed-rated ‘H’, indicating its capability up to 130 mph (210 km/h). According to European tire labeling standards, it receives a ‘D’ rating for fuel efficiency and a ‘D’ rating for wet grip. The rolling noise level measures 71dB.

With this tire, you can expect a secure and confident journey throughout the summer season and into the shoulder months. Every feature has been meticulously developed to provide a safer and more reassuring driving experience.

Dry Performance

The Toyo Open Country AT Plus provides excellent grip and stability on dry roads. Its robust construction and asymmetrical tread design ensure responsive steering and confident handling, making it a reliable choice for daily commutes and highway cruising.

Wet Handling

While rated ‘D’ for wet grip, the tire’s tread pattern is designed to channel water away from the contact patch, aiming to maintain adequate stability. However, drivers should exercise caution and adjust their driving style in heavy rain, as its wet weather performance is not its strongest attribute.

Off-Road Capability

This tire truly shines when the pavement ends. The aggressive block design delivers impressive traction on various challenging surfaces, including dirt, gravel, and uneven terrain. Combined with its reinforced sidewalls, which guard against punctures and cuts, the Open Country AT Plus is well-prepared for adventurous off-road driving.

Durability & Ride Comfort

Built for the long haul, the Toyo Open Country AT Plus boasts a durable construction that contributes to its extended service life. This rugged build also aids in absorbing road imperfections, providing a relatively smooth and comfortable ride for an all-terrain tire, even on less-than-perfect surfaces.

Fuel Efficiency & Noise

With a ‘D’ rating for fuel efficiency, the Open Country AT Plus is not engineered for maximum MPG, a common characteristic of robust all-terrain tires. In terms of noise, it registers at 71dB. While acceptable for its class, drivers can anticipate a moderate hum, particularly at highway speeds.
