Winter is coming; how are your tires?
Ryan Dyle, Ramstein Auto Skills Center mobile equipment servicer, tightens bolts to secure a winter tire to an automobile Oct. 1, 2015, at Ramstein Air Base, Germany. Patrons of the auto center can have their tires changed by staff members or use the facilities to switch them over themselves. (U.S. Air Force photo/Airman 1st Class Tryphena Mayhugh)
