A fire at a west Olympia auto repair shop started in a back storage area and spread to a rack of tires early Wednesday, according to Olympia Fire Department. Firefighters were called to the Firestone Complete Auto Care on Harrison Avenue Northwest near Kenyon Street Northwest shortly after 3 a.m. Wednesday for a report of smoke in the area. They found a working fire inside the one-story building, which does not have a fire alarm or sprinkler system. The cost of the damage was estimated to be $350,000.
