How it works
Tire pressure units vary by country and car — US cars mostly use PSI, European cars use Bar, and the international standard is kPa. Match units against the sticker inside your driver's door.
FAQ
Q. What happens if pressure is too low?
A. Fuel economy drops, wear becomes uneven, and at highway speed the risk of tire damage rises significantly.
Q. Where do I find the recommended pressure?
A. It's printed on the sticker inside the driver's door or in your owner's manual, listed separately for front/rear.
