Is anyone familiar with the Michelin X-One ZP (zero pressure) tires? These look interesting. We'd all be able to leave our spares in the garage or sell them. Less weight, more trunk space. Never have to worry about flats. Will P205/65R15 fit under stock fenders? Nice warranty, too. They do need a monitor system.

On any ZP tires it is required to have a monitoring system. That size may fit depending on you 914. The factory tolerances in the rear fenders vary on our cars. Also the ZP need correct equipment and trained people to mount them or you could damaged the tire or rim or both.
