The Latitude Tour HP ZP (Zero Pressure technology) is Michelin's Crossover/SUV Touring All-Season run-flat tire developed for the drivers of premium crossover and sport utility vehicles that offers temporary extended mobility (up to 50 miles at 50 mph) in the event a puncture results in complete air loss. Used as Original Equipment by BMW, Latitude Tour HP ZP tires are designed to combine run-flat confidence and comfort with handling and all-season traction, even in light snow.The Latitude Tour HP ZP features an all-season tread compound molded into a symmetric pattern that helps balance dry, wet and wintertime traction. Stable shoulder blocks and a continuous center rib boost responsiveness and highway stability, while wide circumferential grooves help resist hydroplaning and 2-D Active Sipes improve handling in rain and snow.The tire's internal structure features twin steel belts reinforced with Michelin FAZ Technology (Filament At Zero degrees) that winds polyester and aramid/nylon cords spirally under the tread area to provide a stable feel and crisp steering, while polyester cord reinforced sidewalls enhance ride quality.Sidewall reinforcement using low hysteresis rubber provides self-supporting strength at zero pressure, helps combat sidewall damage, and maintains cool temperatures to allow longer zero pressure driving while a special bead design helps tires stay securely seated on conventional rims. NOTE: While Crossover/SUV Touring All-Season light truck tires offer all-season versatility including traction in light snow, tire sizes featuring extremely wide tread widths may limit the traction this type of tire can provide in deep snow.
