Tire Rotation
Why do you have to rotate the tires on your car? Don’t they rotate when you drive on them?
———- from Kenneth Kuller of Minneapolis MN
No, Ken, they don’t. What appears to be a spinning tire is actually an optical illusion. Car tires stay put and slide on a special greasy fluid they excrete as the rub along the road. Even wagon wheels turn backwards, as anyone who has seen reruns of “Bonanza” can attest. Again, apperances are deceiving, because in order to make the wagons appear to move forward, they had to run the film backwards through the camera. All that work to maintain a silly illusion! What’s the matter? Are Detroit and Hollywood simply afraid we can’t stand the ugly truth?
