Take 5 minutes every month to check your tires including:
Pressure: Under inflation is a tire’s #1 enemy. Check your tire pressure. A tire can lose up to half of it’s air pressure and not appear to be flat!
Alignment: Is your vehicle pulling to one side, or shaking? Have a tire dealer check the alignment periodically to ensure your car is property aligned.
Rotation: You should rotate your tires approximately every 5,000 miles. Regularly rotating your vehicle’s tires will help you achieve more uniform wear.
Tread: Measure & inspect it. Visually check your tires for uneven wear, looking for high and low areas or unusually smooth areas.
The penny test: place a penny into a tire tread groove. If part of Lincoln’s head is covered by the tread, you’re driving with the proper amount of tread. if you can see all of his head, you should buy a new tire.
