Bridgestone/Firestone Inc. are set to reimburse customers for expenses incurred to replace tires which are included in the company's voluntary recall. Firestone said the reimbursement plan, retroactive to Jan. 1, specifies how customers can be reimbursed for costs related to exchanging the tires included in last week's recall. Firestone is moving to recall and replace 6.5 million of its ATX, ATX II and Wilderness AT tires. Federal authorities are investigating 46 deaths and more than 300 incidents in which the tread peeled off the tires.
