Introduction: How to Check Tire Pressure

It is very important to check your tire pressures every once in awhile because if you have too little or too much air in your tires they can have excessive wear on your tire and decrease the life of the tire. Also driving on low air pressure can damage rims of the vehicle causing run out of the rim and can cause a vibration or a shake. Today im going to show you how to properly check the air in your tires. Air compressor, air chuck, and tire pressure gauge are the tools you need for the task.

Step 1: Check the Sticker for the OEM Specifications for Pressure

The first step when checking your air in your tire is you want to look on the inner part of the door of your vehicle and look for the OEM spec for air in the tires. You do not want to much air in your tires because they will cause uneven wear of tire and if you have a tire pressure monitoring system(TPMS) it will turn a tire light on. The same goes with little air pressure thats why you want to find the sticker with the information.

Step 2: Check the Tire Pressure

Next you want to take the cap off to the valve stem of the tire so you can check the air. Take the air pressure gauge and push the gauge on to the valve stem when you do it if you hear a loud hiss of air you most likely didn't get an accurate check . The air pressure gauge needs to seal to get a proper check of pressure so check a couple times to make sure you get the same measurement.

Step 3: Comparing the Reading to the Sticker

Compare your gauge reading to the sticker on the door and if the pressure in your tires are low add air. You will need an air compressor and an air chuck to add air to your tire. When I add air to tires i push the chuck and it is on right if no air is leaking out the stem and it's all going into the tire, I will add a little and then check with the gauge until the OEM spec is achieved. Make sure you check all four tires. If there is too much air in your tires you can put the pressure gauge on wrong so the tire can leak air but check while your letting air out so you don't let too much air out. Air pressure gauges usually go up in intervals of 2 for the small dots. Tire pressure was good and did not need to add any air.

Step 4: Finishing Up

Make sure you put all your valve stem caps back on and put the tools away and roll up the air house when you have completed putting air into your tires. If you had a tire light on you might have to go for a little drive around the block to let the TPMS sensors reset and read the pressure. If the pressure is correct and your tire light is still on your might have a faulty TPMS sensor and will need a shop to fix.
