Is parking on a hill bad for your tires?


I have heard that parking on a hill is bad for your tires and causes undue stress on them and results in premature tire wear. Is this so?

No, tires get far more wear on exit ramps at highway speeds then when your not moving. Parking on a hill puts stress on another part of the car, called the parking pawl. This is a part inside the automatic transmission that makes the car lock when you put the selector in park. However, putting it into park without first setting the parking brake will make it hard to shift back into gear. If you don't use the parking brake on a hill, the car will lurch back slightly when you take your foot off the brake and this lurch is hard on the transmission, not the tires!
