How much air should I put in my tires?

Proper Tire Inflation

The vehicle manufacturer places a tire inflation placard in each vehicle that gives the proper tire inflation pressures for that vehicle. This placard is located on the driver's side doorpost or outer edge of the door, inside the fuel filler door, or on the inside of the glove box door (depending on the manufacturer). Most manufacturers also list tire inflation levels in the owner's manuals, and if you can't find them anywhere else we have a book of inflation specs here, go ahead and give us a call.

Under normal driving conditions this is the correct tire pressure. Under heavy loads or adverse driving conditions this may be adjusted accordingly, not to exceed the max. PSI located on the tire sidewall. The tire pressure listed on the side of your tire is NOT the correct air pressure for your car - it is the maximum air pressure for the tire.

One thing to note is that your pressures will change with changes in outside temperatures. This shows up especially as we change from fall to the very cold of winter. You need to monitor your tire pressures every couple of weeks during late fall, and expect to add some air to your tires to maintain the proper inflation.

Always check your air pressure when the tire is cold - tires become hot even after driving as little as a mile. If you need to drive to add air check the pressure before you leave and add the difference when you get to an air station. Please call with any questions regarding proper tire inflation or any other questions you may have.
