How much air should I put in my tires?
Proper inflation is the single most important part of tire care. Check or adjust inflation every few months and always use the inflation recommended by the vehicle manufacturer. Checking air pressure should be standard procedure on any routine visit to your vehicle service center for oil services, tire rotations, or general maintenance and repair. For do-it-yourselfers you can find this information in your owner's manual, posted on the edge of the driver's door, on a door post, in the center console, or on the inside of the glovebox door. Be sure to check inflation when tires are COLD: when the vehicle has been driven less than a mile or one hour or more after driving. Use a good quality tire gauge. And don't forget to check the spare!
