Frequently Asked Questions
How often should I check my tire pressure?
Check your tire pressure once a month and before every long road trip; tires naturally lose roughly 1 PSI every 30 days and with temperature drops.
Where do I find the correct tire pressure for my car?
Check the white-and-yellow safety sticker located on your driver-side door jamb (never use the maximum PSI printed on the tire sidewall).
