Checking Your Tire Pressure

Checking your tire pressure regularly is essential to maintain proper tire inflation, which can impact driving safety, fuel efficiency, and the lifespan of your tires. Here are a few simple steps to check tire pressure:

  • Ensure that your tires are cool, meaning they haven’t been driven for at least one hour or have driven for less than a mile.
  • Remove the tire valve cap and use a tire pressure gauge to measure the current psi. Place the gauge onto the valve stem and press down firmly to get a reading.
  • Compare the measured psi to the recommended psi for your tires. If the measured psi is higher, use the gauge to release air until it reaches the recommended level. If the measured psi is lower, add air until it reaches the recommended level.
  • Once the desired psi is achieved, replace the valve cap and repeat the process for each tire.

Adjusting Your Tire Pressure With An Air Compressor

An air compressor can be a convenient tool to adjust tire pressure, especially if you want to avoid the hassle of going to a gas station or tire shop. Here are some simple steps to adjust tire pressure with an air compressor:

  • Connect the air compressor hose to the tire valve stem and ensure a tight seal.
  • Turn on the air compressor and allow it to fill the tire. Keep an eye on the pressure gauge to ensure you don’t overfill the tire.
  • Once the desired psi is achieved, turn off the air compressor and remove the hose.
  • Recheck the tire pressure with a gauge to make sure it’s at the recommended level. Overfilled tires can be dangerous and cause a blowout, so make sure to double-check.

Common Mistakes To Avoid When Adjusting Tire Pressure

While adjusting tire pressure may seem straightforward, there are a few common mistakes to avoid:

  • Don’t rely on visual inspections to determine tire pressure; always use a tire pressure gauge.
  • Avoid checking your tire pressure right after driving or on tires that haven’t been driven for an hour. The heat generated from driving or direct sunlight can cause the tires to expand and provide an inaccurate reading.
  • Make sure to check the recommended psi for each tire and adjust accordingly. Failing to do so can cause uneven wear and damage to your tires.
  • Overfilling your tires can be equally damaging as underfilling. Too much pressure can cause blown-out tires, which can be dangerous at high speeds.
