How to check your tire pressure


Proper tire pressure is a safety issue. Not only does the right tire pressure affect fuel economy and extend the lifespan of your tire, it also affects cornering, braking and stability when driving.

VCC’s auto service technician program department head Jason Devisser walks us through the steps of checking your tire pressure.

What you’ll need:


  1. Don’t set the tire pressure to what it says on your tire. You can find the correct value for your car's tire pressure in the owner’s manual, driver's side door jam, the centre console or the glove box.
  2. Unscrew the cap on the valve stem on the tire (the black stem that protrudes near the hubcap).
  3. Push the pressure gauge evenly onto the valve stem. Check the PSI number on the metered stick. If you hear a hissing sound, you will need to adjust the angle of the pressure gauge.
  4. If the number is lower than determined for your car, use the air pump at a nearby gas station to fill your tire to the right number.
  5. If the number is higher than determined for your car, use the tire gauge to release some air until you have the right number.
  6. Repeat for each tire.
  7. Remember to put the cap back on the valve stems when you’re done.
  8. If you find the tire pressure drops noticeably between checks, be sure to visit a mechanic.

Don’t forget, VCC’s auto body shop is available if you have any questions.
