Q. My car dealer's service
says I should rotate the tires on my four-year-old front-wheel-drive
car, although it's garaged and only been driven 5,500 miles, mostly on
short trips. Is the dealer trying to rip me off? -- J.K. (via Internet)
A. Probably not. That's because front-drive puts most of a car's weight on its front tires, which thus are subject to more wear than the rear tires. You occasionally need to switch them to allow even tire wear. Also, time causes deterioration of auto components. Your car's low miles for its age don't let it escape time. Don't let it sit too much, and take it for approximately an hour's drive at highway speeds so it gets completely warmed up at least once a month.
Q. Is Tesla Motors chief executive Elon Musk overextending himself with his car and battery operations? -- E.R. (via Internet)
A. It seems to be the case. But Musk has actually built and sold highly rated cars. John DeLorean also built cars, but they weren't highly rated. Then DeLorean got into lots of legal trouble.
