Maintaining the correct tyre pressure is crucial for ensuring your vehicle's safety, performance, and fuel efficiency. Many drivers underestimate the importance of proper car tyre inflation, but it plays a significant role in various aspects of your car's operation.

In this article, our team at Natrad Autocare will explore why tyre pressure matters, how to find the right pressure for your car, and the potential consequences of driving on underinflated or overinflated tyres. We’ll also discuss the recommended tyre pressure for most vehicles. 

Why does tyre pressure matter?

Tyre pressure affects several key aspects of your vehicle's performance and safety, making it a critical element of regular maintenance. Here's why tyre pressure matters: 


Properly inflated tyres enhance your car's handling and grip on the road, reducing the risk of accidents. Underinflated tyres, in particular, can lead to poor traction, longer stopping distances, and an increased likelihood of hydroplaning in wet conditions.

Fuel efficiency 

Maintaining the recommended tyre pressure can improve fuel efficiency. Underinflated tyres increase rolling resistance since more of the tyre is making contact with the ground as it sags. It requires the engine to work harder and consume more fuel to overcome this resistance. By keeping the tyres properly inflated, you can improve your car's fuel economy.

Tyre longevity 

Correct tyre pressure helps distribute the vehicle's weight evenly across the tyre tread. This prevents uneven wear and extends the lifespan of your tyres. Overinflated tyres, on the other hand, may cause the centre of the tread to wear out faster and lead to tyre failure. 

Handling and performance 

Properly inflated tyres contribute to better vehicle handling, steering response, and overall performance. Driving on underinflated or overinflated tyres can lead to poor cornering stability and decreased responsiveness.

How to determine the correct air pressure for car tyres 

Check the manufacturer’s recommendations 

The optimal tyre pressure for your vehicle can usually be found in the owner's manual or on a sticker located on the door jamb or inside the fuel filler flap. This information is specific to your make and model.

Use a quality tyre pressure gauge 

Invest in a reliable tyre pressure gauge to check your tyre pressure regularly. Digital or analogue gauges are available, and it's essential to use one that provides accurate readings. If you don’t have your own tyre pressure gauge, you can visit a service centre that specialises in tyre pressure. 

Check tyre pressure when cold 

Tyre pressure can vary with temperature, so it's best to check them when they are cold or before you begin driving. If you've been driving, wait for your tyres to cool before measuring the pressure.

Understand PSI (pounds per square inch)

The recommended tyre pressure is typically given in PSI (or kPa). Ensure that all four tyres are inflated to the recommended pressure for your vehicle. Remember to check the spare tyre as well.

Adjust for specific conditions 

In certain situations, such as carrying heavy loads or towing, you may need to adjust tyre pressure according to the manufacturer's guidelines. Be aware of any special recommendations for these scenarios.

Consequences of incorrect tyre pressure 

Underinflated tyres 

  • Reduced fuel efficiency
  • Increased tyre wear
  • Poor handling and stability
  • Risk of overheating and tyre blowouts

Overinflated tyres 

  • Uncomfortable ride
  • Decreased traction
  • Uneven tyre wear, especially in the centre of the tread
  • Higher risk of damage from road hazards

How do car tyre pressure sensors work?

Car tyre pressure sensors, also known as TPMS (Tyre Pressure Monitoring System), play a vital role in modern vehicles, enhancing safety and efficiency. These sensors work by monitoring the air pressure inside each tyre and transmitting real-time data to the car's onboard computer. There are two main types of TPMS: direct and indirect. 

Direct TPMS utilises pressure sensors mounted inside each tyre, often integrated with the valve stem or within the tyre itself. These sensors continuously measure the tyre pressure, and if a significant deviation from the recommended level is detected, they send a signal to the car's computer, triggering a warning light on the dashboard.

Indirect TPMS, on the other hand, relies on the vehicle's anti-lock braking system (ABS) and wheel speed sensors to detect changes in tyre rotation speed, which can indicate low tyre pressure. Regardless of the type, TPMS plays a crucial role in alerting drivers to potential tyre issues promptly, preventing accidents and promoting fuel efficiency.

What is the ideal tyre pressure for most vehicles?

Typically measured in pounds per square inch (PSI), the recommended tyre pressure varies between car makes and models. Generally, a common range falls between 30 to 35 PSI for standard passenger vehicles. However, your safest bet would be checking your vehicle’s user manual or on the information stuck inside the door jamb. 

It's essential to adhere to these guidelines as they are designed to optimise safety, fuel efficiency, and overall performance. Regularly checking and maintaining the recommended tyre pressure ensures proper traction, handling, and longevity of the tyres.

Should I get my tyre pressure checked by professionals?

While checking tyre pressure is a task that many drivers can perform themselves, there are certain advantages to having professionals conduct regular checks. Professional tyre pressure checks ensure accuracy, as technicians use calibrated equipment to measure the pressure precisely. A big advantage is that they may also identify issues such as uneven tyre wear, damage, or potential leaks that could be missed during a routine self-check. 

Additionally, professionals can offer expert advice on tyre maintenance, including proper inflation levels based on the vehicle's specifications. Many service centres include tyre pressure checks as part of routine maintenance services, making it convenient for drivers to ensure their tyres are in optimal condition.
