Tire Inflation and Wear

Overinflating a tire causes less of the tire’s tread to contact the road surface, poor performance, and fuel mileage problems. The center of an overinflated tire will wear faster than the shoulders resulting in uneven tire wear. The sidewalls are firmer than intended, increasing road shock that can be felt in the ride and increasing stresses placed on suspension components.

Inflate tires according to the manufacturer’s specifications found on the door plate or in the vehicle’s manual. Never exceed the maximum pressure indicated on the sidewall. Manufacturers typically recommend inflating the tire when it’s cold because the air pressure in a tire increases as the tire heats up.
