The Eagle F1 Asymmetric All-Season RunOnFlat (ROF) is Goodyear's self-supporting run-flat Ultra High Performance All-Season tire developed for the drivers of sports cars, sporty coupes and powerful performance sedans who want to enjoy driving their cars any time of the year. In addition to providing temporary extended mobility in the event a puncture allows complete air pressure loss, the Eagle F1 Asymmetric All-Season RunOnFlat is designed to meet challenging road conditions with confidence-inspiring all-season traction, even in light snow.Eagle F1 Asymmetric All-Season RunOnFlat tires use a specialized tread compound that delivers traction in any season. This compound is molded into an asymmetric tread design featuring specific dry and all-season zones to combine race-inspired handling in warm weather with all-season traction in cold temperatures. Powerful outboard tread blocks in the Dry Handling Zone put more rubber on the road to deliver dry traction and handling. The inboard All-Season Zone evacuates water and slush as Traction Teeth increase all-season traction in rain and light snow. While allowing additional biting edges to generate more traction in rain and snow, Tredlock Technology microgrooves lock together for confident grip in turns.The tire's internal structure features twin steel belts reinforced by spirally wrapped polyamide cord cap plies to blend high-performance handling with high-speed durability.NOTE: RunOnFlat tires are only recommended for vehicles that are originally equipped with self-supporting run-flat tires and equipped with a tire pressure monitoring system.
