Dave Roney, 28th Force Support Squadron Auto Hobby Center manager, points out cracks in a tire in the Auto Hobby Center at Ellsworth Air Force Base, S.D., July 2, 2013. The condition of vehicle tires should be monitored since summer temperatures can put added stress on any weak spots and can cause a blowout. (U.S. Air Force photo by Airman 1st Class Ashley J.
