Which company introduced PAX system for the production of tires?

Michelin introduced the system PAX system in late 2000. Michelin's innovation is a new tire system called PAX. It is dubbed a "system" because these tires require a special wheel and an insert in order to work. The wheel is designed to keep the tire on the rim even if all the air is removed and you are driving at 55 miles per hour. The insert prevents the tire from totally collapsing onto the rim.
