As I mentioned in the previous post I cannot assume my audience knows everything I know, therefore we'll start with some basics. Now that winter is upon us, you might notice your tires seem flatter than usual. This is because of the dropping temperatures which causes the air inside to become dense thus lowering the pressure inside the tire.
There are two places you can check that will provide accurate information: the driver-side door jam of your vehicle.
And the owners manual for your vehicle, which is hopefully in your glove-box. You can check online for this information, however I would save that for a last resort.
If you were paying attention to the illustrations, you'll notice that there is more information in the owners manual than on the door jam. As indicated by the chart in the manual, you'll notice that as the temperature goes down, the recommended tire pressure goes up. Lets check the tire pressure.
Use a tire pressure gauge to check the pressure by placing the nozzle of the gauge up to the head of the valve stem. Make sure they're lined up and press the gauge gently yet firmly onto the valve stem. You'll hear some air seep out, press firmly to create a seal between the gauge and the stem. If you have a good seal, air should not continue to pour out. It may take a few tries if this is your first time, if you need to, reset the gauge by pushing the pressure indicator back into the gauge and try again.
In this case, my front left tire pressure is at 33psi. To top it off one will need a pneumatic air compressor. Just plug it in, let it charge up and fill your tire to the correct pressure. In my case I'm going to hold off on topping it off for just 2psi difference. At what level would I fill it you ask? I'll fill it at a 5psi difference. Don't forget to check the other 3 tires.
I hope you learned something today and thanks for tuning in!
