Toyo Open Country A/T III EV
Meet the Toyo Open Country A/T III EV, an all-terrain tire purpose built for electric trucks and SUVs. It handles extra curb weight and instant torque while staying composed on pavement, gravel, and light trails. An efficient tread keeps road noise in check and helps manage rolling resistance, and a cold-weather compound with dense siping boosts wet and light-snow grip. If you want daily comfort, reliable traction, and EV-ready durability for towing and gear, the A/T III EV delivers.
Key features of the Open Country A/T III EV
Built for modern electric vehicles, the Open Country A/T III EV blends versatile traction with EV-focused construction. Reinforced casing and bead areas help control higher axle loads and the immediate torque of electric motors. Staggered shoulder blocks and open channels bite on loose surfaces while an optimized pattern keeps on-road noise pleasantly low. A cold-weather compound with dense siping improves grip in rain and light snow, and stone ejectors help protect the tread on gravel.
On‑road and off‑road performance
A cold-weather compound keeps the tread flexible as temperatures drop, which preserves traction on cold, wet roads. Dense, multi-directional siping adds biting edges that enhance braking and cornering on rain-soaked pavement and in light snow. Wide circumferential and lateral grooves move water away to resist hydroplaning. For frequent ice or deep, persistent snow, a dedicated winter tire remains the best choice, but for mixed seasons the A/T III EV delivers dependable performance when driven with care.
Durability and tread life
Electric vehicles place unique demands on tires, and the Open Country A/T III EV is built to handle them. Reinforced construction helps manage heat and resist tread deformation under higher curb weights and instant torque. A robust belt package and a cut and chip resistant compound add resilience on gravel and job sites. Maximize tread life by maintaining proper inflation, rotating on schedule, and keeping alignment in spec.
Sizes, load ratings, and EV fitment
Popular EV-friendly sizes for the Open Country A/T III EV include 275/65R20, 275/60R20, and 275/70R18, with load indexes suited to heavier electric trucks and SUVs. Match or exceed your vehicle's door-jamb label for size, load index, and speed rating, and confirm wheel diameter and offset before ordering. If you drive a half-ton EV or a performance oriented electric SUV, choose a load range that supports your daily payload and towing needs. For vehicles such as the Rivian R1T and R1S or the Ford F-150 Lightning, verify OE specs and consider a professional fitment check to ensure clearance and proper TPMS calibration.
Price and value
Pricing for the Toyo Open Country A/T III EV varies by size and load rating. Consider total value, including on-road comfort, off-road capability, EV-ready load capacity, and the potential effect on range. Proper inflation, regular rotations, and alignment maintenance can extend service life and help control cost per mile. Watch for seasonal promotions, installer bundles, and road-hazard coverage, then confirm your size and ratings and schedule professional mounting and balancing.
A/T III EV vs non‑EV all‑terrain tires
Compared with conventional all-terrain options, the Open Country A/T III EV is tuned for the weight, torque, and regenerative braking of electric vehicles. Its reinforced casing, EV-appropriate load indexes, and balanced tread design help maintain stability and ride quality under load. Non-EV A/T tires can fit some electric trucks and SUVs, but the EV variant often delivers better control and may help preserve efficiency. If your driving mixes highway commuting, trails, and towing, the A/T III EV offers a purpose built blend of traction, durability, and refinement.

Do you have a question about Open Country A/T III EV 275/70R18 SL 116H?
Yes, Toyo Open Country A/T III EV tires are a dependable option for EV trucks and SUVs, featuring an aerodynamic sidewall to reduce wind drag and an EV-optimized tread design for enhanced durability, traction, and ride comfort. Additionally, they include specialized features to boost performance in snowy conditions and on rough terrain.
Toyo Open Country A/T III EV tires are primarily manufactured in Japan. However, production also takes place in other countries, including the United States, Serbia, Germany, Thailand, Taiwan, China, Malaysia, and various other locations worldwide.
The Open Country A/T III EV uses a cold-weather compound and dense siping to improve traction in wet and light-snow conditions. Many sizes in the A/T III family carry the 3PMSF symbol, but availability can vary by exact size and load configuration. Check the specifications for your size to confirm winter designation. In regions with frequent ice or deep, persistent snow, a dedicated winter tire will deliver the best braking and acceleration.
All-terrain patterns can modestly affect efficiency and cabin noise compared with highway-terrain designs. The Open Country A/T III EV is engineered to balance traction with on-road refinement and rolling efficiency suited to EVs. Results depend on size, load rating, pressure, and alignment, so keep tires properly inflated, rotate consistently, and avoid unnecessary upsizing or aggressive wheel fitments. Many drivers find the ride and quietness competitive for an A/T while gaining the off-pavement capability they want.
Toyo offers a limited warranty, and mileage coverage typically varies by size and category, such as P-metric versus LT-metric. Review the specific warranty for your chosen size, and ask your retailer about any road-hazard coverage or satisfaction trial. Proper maintenance, including correct inflation, routine rotations, and alignment checks, helps you stay eligible for coverage. Keep your purchase documentation and service records in case you need to file a claim.
Yes, provided the tire's size and load index meet or exceed your EV's requirements. Towing increases load and heat, so verify the door-jamb pressures for towing and never exceed wheel or vehicle limits. Choose a load range appropriate for tongue weight and payload, and make sure the hitch setup and suspension are rated for the trailer. Before trips, check alignment, balance, and pressures, and re-torque lugs after installation or wheel changes.
Match or exceed the load index on your vehicle's door-jamb label. EVs are heavier and apply torque instantly, so choosing the correct load range and maintaining proper inflation are essential for stability and tread life. Some applications use XL or P-metric sizes, while others require LT-metric fitments. If you tow, account for tongue weight and cargo, and when in doubt consult your owner's manual or a professional installer.
