Firefighters were on the scene Tuesday morning of a large fire at a tire storage facility in Concord. Crews arrived around 3:15 a.m. at the facility at the intersection of Meadowview Avenue Southwest and Old Charlotte Road to find smoke billowing from the building as well as heavy flames. It took firefighters about 25 minutes to get the fire under control. Investigators said nobody was in the building, which is used for tire storage, at the time of the fire but they're still searching for the cause.
