The Yokohama AVID ENVigor ZPS (Zero Pressure System) is a high-performance all-season run-flat tire developed for sports cars, coupes, and sedans requiring extended mobility capabilities in the event of complete air pressure loss. This tire provides temporary self-supporting mobility for distances up to 50 miles at 50 mph following punctures, allowing drivers to reach service facilities without requiring roadside tire changes. The ENVigor ZPS features an all-season silica tread compound molded into an optimized five-rib directional pattern incorporating linked shoulder blocks and a continuous tapered center rib to increase tread rigidity, while independent intermediate blocks, angled grooves, and adaptive 3D sipes enhance wet traction and all-season capability. Yokohama specifically recommends ZPS tires only for vehicles originally equipped with self-supporting run-flat tires and tire pressure monitoring systems.
The Yokohama AVID ENVigor ZPS utilizes robust internal construction featuring twin steel belts reinforced by jointless nylon belt covers and belt edge strips, with two rayon cord body plies providing predictable handling characteristics while Yokohama's specialized ZPS sidewall reinforcement temporarily supports the vehicle's weight during zero-pressure operation. Available in sizes for 16, 17, and 18-inch rims with H-speed (130 mph), V-speed (149 mph), and W-speed (168 mph) ratings, the tire delivers up to 10/32 inch tread depth depending on size, balancing initial wet performance with reasonable tread life expectations. The directional tread pattern efficiently evacuates water while maintaining mechanical grip across varied weather conditions including light snow, providing year-round versatility uncommon in high-performance tire categories. The ENVigor ZPS serves drivers of performance vehicles requiring the safety and convenience of run-flat technology while maintaining responsive handling, confident all-season traction, and the peace of mind provided by extended mobility capabilities that eliminate concerns about being stranded due to tire punctures during daily driving or long-distance travel.
