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.
