How To Check Your Car’s Tire Pressure and Inflate a Tire

Maintaining correct tire pressure is important for safety and fuel efficiency.

Regularly checking and maintaining the tire pressure of your car is important for safety reasons. It can save you money, too! Newer models come equipped with a TPMS that lets you know when anyone particular tire needs to be inflated more or less based on measurement relative to other tires in use at the time (when 25% under-inflated).

Finding Proper Inflation Levels

You should always check the tire pressure on your car, as it can vary depending on what you drive. If you’re not sure how to do this, refer to the sticker placed near the driver’s side doorjamb or in your owner’s manual for instructions and guidance. You’ll usually find these numbers listed in pounds per square inch (PSI) but some newer vehicles may list them using metric measurements like kilopascals (kPa).1 PSI equals approximately 6.89475729 kPa and 100 kPa equals about 14.50 Psi so keep this conversion handy!

Types of Air Pressure Gauges

The air pressure in a car’s tire is determined by the type of gauge used to measure it. Analog gauges generally come in two styles, stick and dial. Stick types are sometimes referred to as “pen” or “pencil gauges,” due to their similarity in size and shape, displays the tire’s pressure on a stick marked with PSI or kPa numbers while Dial Gauge utilizes an analog clock face that often provides easier-to-read level measurements for its user.

Digital gauges are becoming more popular with new technology and battery-powered models. They’re fairly easy to use thanks to their digital readout, quality units can be found for less than ₹3000 or even ₹10000 depending on the type you need.

How To Check A Tire’s Air Pressure

Every tire should be inspected at least once a month. The best way to do this is with the use of your trusty pressure gauge. Remove the screw-on cap and press on that valve stem until it feels snug–don’t worry if you feel resistance or slight pain; there’s no need to go overboard here! Check out how much air has been pumped in by measuring either your stick indicator, dial indicator, or digital readout screen, and make sure everything checks out okay before replacing the rubber cover over top.

Make sure that you are checking your tires when they’re relatively cold. If you check after a long drive, the heat will make it seem like the pressure is higher than what’s actually inside. It can be misleading and lead to an inaccurate reading which could cause unsafe conditions on any road trip!

The best way of avoiding this problem would be to invest in an electric air pump for cars rather than use those unreliable pop-up stick types. You’ll get more accurate results for less money spent overall with one purchase of better equipment at once instead of upgrading or replacing cheap gauges constantly because they aren’t reliable enough over time.

How to Inflate Tires

You can inflate your tires at the fuelling station with a foot-operated pump, or you could carry an electric air compressor. It is preferable to use an electric air pump rather than a manual pump.

  • Unscrew the air valve cap on your wheel.
  • Briskly push the tire pressure gauge into the valve and read the reading on the pump.
  • If the reading is below the recommended PSI, attach your air hose to the tire’s valve and turn it accordingly.
  • Ensure that you recheck the pressure with your gauge to confirm whether or not the tire is correctly inflated and it will take roughly one to two minutes for each tire to reach normal pressures.
  • Put the tire air valve cap back on

Wrapping Up

One of the hardest parts about keeping your tires properly inflated is visually inspecting them. I always make sure to look at my car’s wheels when filling up at a gas station, so that if there are any problems with tire pressure, they can be fixed right away! The best way to get in the habit and keep track of this important task is by setting reminders on our phones or calendar once every month (or six weeks).
