Another estimated 100,000 recalled tires were replaced Monday and Tuesday, bringing the total to about 660,000 as the first air shipment of replacement tires arrives today from Bridgestone Corporation manufacturing plants in Japan. The speed of the recall continues to accelerate with Bridgestone/Firestone and other tire makers ramping up production of replacement tires and consumers turning to the Internet for retail locations, reimbursement forms and lists of approved replacement tires.
