CLERMONT-FERRAND, France —Group Michelin and Pirelli S.p.A. have agreed to cooperate on developing Michelin's Pax integrated run-flat tire-wheel system. By joining forces on this project, Michelin and Pirelli said they believe they can accelerate the development curve of the system and provide vehicle makers and consumers with a broader supply and market support base by as early as next year.
The agreement, announced jointly by the two firms Feb. 22, will bring Pirelli's ``technological expertise of total mobility and high performance'' to the unique tire-wheel system that Michelin has been developing for the past several years.
The new partners already have identified several areas of technological improvements to the Pax system, which consists of a new tire design, a flat-base profile wheel, a flexible support ring and a low-pressure detector.
Both companies emphasized Pax offers run-flat capability without compromising other performance criteria—such as rolling resistance—and offers vehicle designers greater latitude in specifying tires for new vehicles.
The firms did not comment on the value of the agreement.
