Every tire is registered
War housing trailers.
Tires for war housing trailers do multiple duty. These 150 prize "shoes" have been returned from war housing areas after removal from trailers delivered from the Los Angeles plant of Western Trailer Company. They will be used in further deliveries of new trailers.
Every tire is registered, and returns are checked against deliveries.
