Manage Your Car's Tyre Pressure

Ultimate Guide To Check And Manage Your Car's Tyre Pressure

Tyres are one of the most crucial components of a vehicle.

Low tyre pressure can cause excessive friction with the surface of the road, resulting in tyre burn. If you don't check your tyre pressure regularly, you could end up spending more money down the road or even decreasing the performance of your car.

Therefore, it is important to check your tyres at regular intervals (once a month is recommended).

This article covers everything about tyre pressure and how you can check it.


What Is Tyre Pressure? Why Should You Check It Regularly?

The quantity of air added to your tyre determines your tyre pressure. It's measured in psi, bar, or kPa (pounds per square inch). The appropriate pressure for your tyres is recommended by your vehicle's manufacturer.


A tyre's pressure naturally decreases over time (normally approximately 1 psi (0.076 bars) every month). Other air leaks may increase pressure loss as a result of:

  • Accidental puncture
  • The valve must be replaced whenever a tyre is replaced.
  • The valve cap is required for an airtight seal.
  • The wheel: every time a tyre is installed, it should be cleaned.
  • Follow the vehicle or tyre manufacturer's recommendations, especially when it comes to operating circumstances (loads/speeds, etc.).

Here are a few reasons why you should frequently check your tire pressure.

  1. Avoid heat build-up and rolling hazards
  2. Avoid side flexing and tyre squirming.
  3. Help optimize tyre performance and fuel economy.

How Can You Check Your Tyre Pressure?

Make sure you're using a pressure gauge with the same unit of measurement as the pressure guidelines for your car before you begin.

Once you've found an appropriate pressure gauge, follow these steps:

  • After removing the valve dust cap from the tyre valve stem, mount the pressure gauge onto it.
  • To acquire an accurate reading, press down evenly on the valve stem with the gauge.
  • Determine if you need to deflate or inflate your tyres by checking the pressure gauge reading.
  • If your tyres need to be inflated, use an appropriate pump and add tiny quantities of air at a time to avoid over-inflation.
  • If your tyres need to be deflated, push on the metal pin on the valve stem with the point of a flat-head screwdriver to release air.
  • Between inflating and deflating, take regular pressure readings using the pressure gauge.
  • Check the pressure in all four tyres on your automobile, since the pressure in each tyre might differ dramatically.

Don't forget to inspect the spare tyre as well. This is often ignored, but you never know when you may need it.


What Is The Recommended Tyre Pressure For My Car?

Every passenger car has a different tyre type and so tyre pressure. You can get recommended tyre pressure for your vehicle at:

  • In the owner's manual for the vehicle.
  • There is a sticker on the driver's or passenger's door or the fuel tank door.

Note: The number on the sidewall of your tyre will not tell you how much pressure you need in your tyre.


How To Obtain Perfect Pressure For Your Tyre?

Tyres that are under-inflated or over-inflated might burn out quicker than planned, have less gripping, and will use more fuel. It only takes a few minutes once a month to maintain your safety and tyre lifespan.


Your operational expenses will be reduced if you keep your tyres at the proper pressure. Under-inflated tyres are more likely to overheat, consume more gasoline, and wear out faster. Over-inflation can also shorten tyre life, diminish grip, and create steering issues.

    • Wear

A tyre that is 20% underinflated will cover 20% less distance. On a total mileage of 25,000 miles (40,000 km), this equals a loss of 5,000 miles (8,000 km).

    • Fuel consumption

Your car's complete weight is supported by the air pressure in your tyres. Maintaining proper tyre pressure is important for keeping you and other road users safe, as well as enhancing vehicle performance, lowering fuel costs, and ensuring that your tyres last as long as possible. As a result, it is one of the most overlooked characteristics of a vehicle.
According to research conducted by the National Highway Traffic Safety Administration (NHTSA) in the United States, every 1% reduction in tyre pressure results in a 0.3 percent decrease in fuel economy. Fuel consumption increases by 2% when the tyre is inflated by 10%. Fuel usage increases by 4% when costs are 20% below inflation.


Nitrogen Vs Compressed Air? Which One Should You Prefer?

Traditionally, people use compressed air to fill tyres. Nitrogen makes up 78% of air and oxygen makes up 21%. The use of nitrogen for tyre filling has grown dramatically. It is possible to blend nitrogen with compressed air.


Most tyres may be filled using air or nitrogen as long as the car manufacturer's recommended pressures are followed. Here are some reasons why nitrogen is increasing in popularity.

Benefits Of Using Nitrogen In Tyre

  • It lowers your tyre's operating temperature.
  • Has a better level of stability than oxygen.
  • Increases the quality of the ride.
  • Extends the life of tyres.
  • With respect to tyre temperature, nitrogen provides a more stable pressure range.


What is Valve?

The air in a tyre is under pressure and supports the vehicle's weight. The tyre valve lets air under pressure into the tyre chamber (formed between the casing and the rim) when it's needed and then lets it out when it's time to adjust the pressure or remove the tyre.


A high-pressure air-line adapter or a pressure-testing gauge can be readily installed on the valve stem.


Role Of Valve and When To Change It?

  • It helps you to maintain the proper tyre pressure.
  • It helps to keep moisture outside the tyre.
  • The valve cap plays an important role in helping block dust particles from clogging the valve. Use a cap with a high level of quality.

Valves are usually made of rubber and need to be replaced over time. They can get damaged at high speeds, causing an air leak.



Your car tyres are one of its most important systems. Use the methods listed above to get a rough estimate of the tyre pressure and go for a drive without worrying about being pulled over for dangerous driving. They are also crucial aspects of safety. Make sure to check the pressure in your tyres regularly.
