How To Put Air In Tires Without Gauge – The Easy Way!

Filling the proper amount of air in the tires is easy with a pressure gauge. It gets puzzling if one has to fill air into tires without this handy gear.

So, how to put air in tires without gauge? To do that, you will need to first test the pressure point and then fill the air. To do it rightly, here are 3 reliable methods –

  1. Using Hand & Air Pump.
  2. Eyeballing & Digital Tire Compressor.
  3. Deflate Tires Fully & Inflate Recommended Air.

All of the above techniques won’t take long to complete. However, you might need to follow the instructions correctly. Now, Let’s Get Into It!

How To Put Air In Tires Without Gauge

This is How To Put Air In Tires Without Gauge!

Each of the given methods is different and requires tools like an air compressor or pump. So, be sure to bring a nice one before trying any step.

Method #1: Using Hand & Air Pump.

  • Press the tire using your hand.
  • Be sure to use slight pressure so that you can understand the tires inside air level.
  • If it seems soft and fluffy-like, then this means the tire pressure is low. And the hard-core tire which seems hard to press indicates an overinflated air level.
  • After knowing the tire air level, now bring the tire pump and insert the hose inside the air valve of the tire. Wait for 1 to 2 minutes to fully inflate.
  • In case your tires are overinflated, then deflate them by pressing the metal pin inside the air valve with a screwdriver.
  • Be sure to do that same thing on other tires if they need air.

Method #2: Eyeballing & Digital Tire Compressor.

  • Start by, placing your truck on flat and even ground to avoid facing mess.
  • Inspect the 4 tires (both front and back side) to find any unevenness on them. If you locate one or more tires that are jutting out, then it indicates low pressure.
  • Use a digital tire compressor that has around 80 – 100 PSI like the AstroAI Air Compressor.
  • Turn on the truck’s engine before inserting the hose.
  • Insert the inflator pump into the 12V outlet of your truck tightly.
  • Take out the valve cap from the air valve and mount the air nozzle inside it.
  • Hit the inflation switch to switch on the air compressor.
  • Set a specific PSI by using the M button.
  • To adjust the pressure level, use the (+ and –) buttons.
  • Wait for a while until it automatically stops.
  • Turn off the inflation switch and detach the plug.
  • You might need to do the same thing on other tires if they need air.

Method 3: Deflate Tires Fully & Inflate Recommended Air.

  • Jack up your truck’s front and back areas. Lift them to a level height.
  • Take out the valve cap from the air valve stem (one tire at a time).
  • Reach the valve metal pin and use needle-nose pliers to twist it on the left. It’ll help deflate the tire fully.
  • Now, check the user manual or driver’s side door label to find the exact PSI number of each tire.
  • Take an air compressor or pump to inflate the tire at a specific range.
  • Let other tires be inflated as you have done before.

Note: Since you aren’t using the pressure gauge, the accuracy of tire pressure understanding can be defined in level (high or low).

Frequently Asked Questions

1. How to put air in tires at gas station?

In order to put air in tires at the gas station, just follow the given steps which would require no tools. Here are the instructions:

  1. Drive to the local gas station’s air compressor area.
  2. Ensure the tires are cold and remove the plastic valve tube from the air valve.
  3. Adjust the PSI level on the machine.
  4. Insert the air compressor hose mouth in the valve stem.
  5. Fill air for 5 to 10 seconds.
  6. Check the tires if they seem level and even use your hand. If it doesn’t seem enough, again fill air for 10 seconds.
  7. Remove the hose and insert the valve tube.

2. How to tell which tire needs air?

To tell if the tire needs air or not, it can be done by using the tire pressure gauge. Other than this tool, using your hands and eyes to closely inspect the tires will help to know the approximate air level.  

3. How much air do I fill my tires with?

Nearly all passenger cars have a specific tire air rate to put air for around 31 – 32 PSI (Pounds Per Square Inch) in a cold state. However, if talking about modern cars, the tire recommended air rate is 32 – 35 PSI on average.

Wrap Up

Facing a flat tire when you don’t have a pressure gauge to check the pressure is not always a annoying thing if you know how to use the above methods.

Ensure that the tire isn’t overinflated as this kind of situation will give a puncture experience. Plus, be careful about the weather, especially in winter and summer which affects the tire pressure. Hopefully, this guide about how to put air in tires without gauge helps you. See You Again!
