At first I thought that the tire lock referred to was like a wheel lock on modern cars, but I don't think such things existed in the 1930's. More likely he was talking about trying to get the spare tire off the car, and the difficulty of doing that. I remember seeing photos of those old cars and I'm pretty sure the spare tires were affixed to the outside of the car somehow. So there would need to be some kind of fastener or lock to keep the wheel in place and secure. Trying..."to wrest the 1927 tire lock of its prey..." supports this theory.
