Re joemanning's David Rudnick bio-ette: There's no way that's the Rudnick that ran this emporium because nothing there points to his owning one. The only auto industry gig he had, apparently, was "credit specialist". I googlefied the tire company, checked D.C. business directories, etc. but found nothing helpful. Looks like this case is closed, Mr. Chan.

Per 1920 census, Rudnick was David Samuel Rudnick. He was born in 1883 in Galveston, Texas. He was the son of Russian-Jewish parents. In 1911, he entered the US in Laredo, Texas, from Mexico, and reported his destination as New York City. In the 1930 census, he was still in Washington, and worked as a "credit specialist" in the auto business. He was married to Henrietta, and had a 17-year old daughter named Eileen. He moved around quite a bit. According to his WWII draft registration, he was living in 1942 with Henrietta in Philadelphia. He listed his employer as Remington Rand Co. Per California Death Index, he died in San Diego on June 29, 1951.
