This A/S IV fits a variety of older vehicles and is available in select white sidewall sizes, perfect for making a statement in your classic car. All-Weather Tread Pattern Squared off tread elements form an effective pattern of distinct gripping edges for year round traction. Wide circumferential grooves and lateral grooves promote excellent wet traction by channeling water out from the contact patch. Optimized Tread Void Tread void, created by grooves and sipes, is greatest at the center of the tread to aid traction, then decreases gradually toward the shoulder area for overall, even treadwear. Variable sizing of the tread elements helps reduce noise. Durable Rubber Compounds Rubber compounds used throughout the tire are formulated for durability and performance. The combination of tread stock and tread pattern delivers even wear and excellent mileage.
