Tire Clock Wall Clock Tire shaped wall clock with black dial and mechanic tool hands. Plastic case and lens. Diameter: 14". The clock is styled as a low-profile, high-performance tire on a sporty alloy wheel, through which you can see a drilled disc brake rotor and the brake caliper. Behind this is a burgundy clock dial with gray numbers and silver markings. The three hands are shaped like mechanics' tools, the most obvious being the hex wrench-shaped hour hand. While there's no brand name or logo on the tire sidewall, there is the size: 245/40ZR/18, definitely a serious tire.
