The Mastercraft A/S IV tire is an entry level, all-season tire designed for the value-oriented consumer. This tire fits a variety of older vehicles and is available with a white sidewall option in several sizes. Mastercraft A/S IV tires feature squared-off tread elements that form an effective pattern of distinct gripping edges for year-round traction. Wide circumferential and lateral grooves promote excellent wet traction by channeling water out from the contact patch. The optimized tread void, created by grooves and sipes, is greatest at the center of the tread to aid traction and then decreases gradually toward the shoulder area for overall even treadwear.
