Toyo Open Country A/T III EV: an all-terrain all-season tire engineered for electric trucks and SUVs

The Toyo Open Country A/T III EV is an all-terrain, all-season replacement tire developed specifically for the fast-growing segment of electric trucks and SUVs. Its mission is to deliver a capable on-road and off-road upgrade while addressing the realities that make EVs different: instant torque, rapid acceleration, additional vehicle weight, and the importance of efficiency for range. The tire also carries the Three-Peak Mountain Snowflake (3PMSF) symbol, signaling severe-snow capability for drivers who want confident year-round dependability.

Engineered for EV use: stability, efficiency, and everyday consistency

Electric vehicles can place higher loads on tires and deliver power more abruptly. The A/T III EV is designed to remain predictable and confidence-inspiring under these conditions by pairing an advanced tread compound with an optimized tread layout. The intent is to balance reduced rolling resistance (supporting efficiency), durability, and road manners so the tire feels composed on highways, city streets, and the mixed routes many drivers experience every week.

Aerodynamic efficiency: AeroWing® and a smoother sidewall to reduce drag

Toyo highlights efficiency-oriented design choices, including an AeroWing® sidewall lug concept and a smoother sidewall area. This approach targets reduced wind drag around the tire, supporting better energy use—an especially meaningful benefit for EV owners looking to preserve range on longer trips and during sustained highway driving.

All-terrain traction and durability: built to leave the pavement

A true all-terrain tire needs to keep traction when surfaces become uneven. The A/T III EV uses staggered shoulder lugs to add biting edges, a void distribution designed to support traction and handling stability, and stone-ejecting blocks intended to help push stones out of the grooves. Toyo also emphasizes protection against cuts and chips, which matters when your routes include gravel roads, work sites, or weekend adventures beyond smooth asphalt.

Winter confidence and comfort: 3PMSF capability with a quieter ride

For year-round drivers, the 3PMSF severe-snow marking provides a strong winter-readiness cue. Toyo also highlights traction-focused tread elements such as 3D sipes and added lateral grooves designed to enhance grip across surfaces, including snow. At the same time, the tread design and compound are positioned to deliver a quiet, comfortable ride, helping reduce fatigue and cabin noise on longer commutes and highway journeys.

Warranty and trial offer: a clear value proposition for an EV-focused A/T

The Open Country A/T III EV is backed by a treadwear warranty up to 65,000 miles (depending on size and applicable terms) and a stated 500 miles / 45 days trial offer. Together, these programs reinforce the tire’s positioning as a balanced EV all-terrain option focused on capability, efficiency, and long-term durability.
