Discoverer AT3 4S 265/70R18 116T OWL

Cooper's Discoverer AT3 4S is a true all-season all-terrain tire engineered for light trucks and SUVs that need reliable year-round performance, including in winter conditions where it carries the Three-Peak Mountain Snowflake rating. The tire uses Adaptive Traction Technology with staggered shoulder lugs and an aggressive tread pattern to deliver confident off-road grip while maintaining the on-road handling characteristics — rated at 5.0 out of 5 for dry handling — that professional shops expect from a daily driver tire. Snow Groove Technology incorporates dedicated biting edges that trap and compress snow within the grooves, leveraging snow-on-snow traction for improved winter performance without sacrificing year-round stability.
