NEW YORK (June 29)—The Goodyear-Groupe Michelin run-flat tire joint venture has stirred little immediate reaction from automotive companies and tire competitors. General Motors Corp. and DaimlerChrysler A.G. said it is too early to comment on the impact of the agreement. Ford Motor Co. believes the pact and the system will generate curiosity, but is hesitant to prophesy on the results. "We believe that our customers will be interested in these technologies, but we can´t predict how quickly they´ll be accepted by consumers, and so we can´t really predict how quickly we´ll be moving to introduce them into our vehicles," a Ford spokesman said. Bridgestone Corp. wouldn´t comment on the deal, and Continental A.G., while not addressing the Goodyear/Michelin agreement specifically, questioned the need to change overall run-flat technology. "A change in tire/wheel system technology cannot be justified due to tire punctures being so uncommon statistically," a company statement said. "An inexpensive and simple way of extending mobility is what vehicle manufacturers and consumers want."
