United Tire and Service dealers sponsored a fundraiser to benefit the American Heart Association to mark their first anniversary as a tire group : Tim Steigerwalt, partner of United Tire and Service; Allyson Lindauer and Cara Feldman of the American Heart Association, and Bill D'Amico, store owner of United Tire of West Chester. Fourteen dealers formed the United Tire and Service LLC tire group one year ago to increase their buying power.
