Keep Tires Rolling Efficiently - Maintain proper air pressure to minimize tire failures

摘要

By the time you can visually detect low air pressure in a tire, it's already too late. You have likely shortened its life, and could potentially cause a tire failure at an untimely moment. "Contractors can identify if a tire is flat," says Wayne Birkenholz, manager of global field engineering, Firestone. "But relying on visual inspection is a matter of degrees." For example, let's say the optimum inflation pressure for a tire is 100 psi. "Can you tell when it's 20 lbs. underinflated?" he asks. "The tire may not look low at that level. You can tell that it has air in it, but you can't tell if it has 70 lbs. or 100 lbs. But that much difference could certainly affect performance."
