Toyo Tires Open Country A/T III

TL;DR A 3PMSF-certified all-terrain tire (UTQG Traction A, Treadwear 600) that independent tests show handling deep snow and hard pack well; a capable year-round choice for trucks and SUVs that see real winter use. ## What it is and how it performs P-metric sizes carry UTQG grades 600/A/B and a 3PMSF severe-snow stamp. SnoWest field testing found strong deep-snow and hard-pack results; TireTerrain independent tests show solid off-road scores across dirt, mud, and rock. Owner data trends toward long tread life consistent with the high Treadwear band; cross-platform odometer confirmation remains under the two-source threshold. This page covers the AT3 model across its full size range. ## Who should buy this, and who should skip it Right fit for a truck or SUV owner needing certified severe-snow capability with solid tread life and mixed on/off-road use. Skip if your use is pavement-only and quiet is the priority; a grand-touring all-season will outscore it on those axes. ## Safety and environmental impact Cured-rubber-and-steel construction; no chemical-exposure pathway from the tire in normal mounting and use. A Prop 65 warning appears on the listing, standard for tires. Tire-wear particles and 6PPD-quinone in road runoff are category-level concerns shared by all tires.
