Yokohama tires are designed to perform better, keep you safer and take you further. The ADVAN Sport Z.P.S. combines Yokohama™s signature performance with Zero Pressure System runflat capabilities. It features variable rounded grooves to maximize performance on wet surfaces and a nanotechnology tread compound to increase flexibility, durability, and contact area for better wet and dry traction. In the event of a total loss of air pressure, Yokohama™s advanced runflat technology maintains the performance and stability of the ADVAN Sport Z.P.S. for up to 50 miles and 50 mph. Therefore, your vehicle must have a functioning tire pressure loss warning system to alert you in case a flat tire goes unnoticed. ADVAN Sport Z.P.S. tires do not require specialized wheels. They are designed to work with wheels that meet Tire & Rim standards. Consult your vehicle manufacturer for any requirements when replacing original equipment runflat tires.
