Firestone tire service truck at Tacoma Speedway circa 1915. The location was the Tacoma Speedway, about seven miles from Tacoma. The occasion was probably the three auto races which composed a great part of the summer Montamara Festo. The Firestone service vehicle was there in all likelihood to supply replacement tires to the cars which raced 100, 200, and 250 miles respectively. 1915 was the first year that the new "lattice" track was in use. It had replaced the old dirt track but racers still had to deal with unexpected difficulties such as splinters.
