Tyre Pressure & Your Wallet: Save on Fuel Mileage, Jan 2026
With petrol prices remaining a significant household expense across Australia, every little bit counts when it comes to saving money at the pump. While many factors influence fuel consumption, one often-overlooked aspect is your vehicle's tyre pressure. Maintaining the correct tyre pressure is not just a safety issue; it's a direct line to improved fuel efficiency and a lighter load on your wallet.
The Link Between Tyre Pressure and Fuel Efficiency
Under-inflated tyres increase rolling resistance. This means your engine has to work harder to move the vehicle, resulting in higher fuel consumption. Think of it like riding a bicycle with flat tyres – it requires significantly more effort. Conversely, properly inflated tyres minimise rolling resistance, allowing your vehicle to glide more efficiently and use less fuel. Optimising your tyre pressure can lead to substantial savings over time.
Understanding Recommended Tyre Pressure
The correct tyre pressure for your vehicle is not a one-size-fits-all number. It's crucial to consult your vehicle's owner's manual or the tyre placard, typically located on the driver's side doorjamb. This placard provides the manufacturer's recommended tyre pressure, usually expressed in PSI (pounds per square inch) or kPa (kilopascals). Remember that the pressure listed is usually for cold tyres, meaning tyres that haven't been driven on recently.
How to Check and Adjust Tyre Pressure
Checking your tyre pressure is a simple task that can be performed at most petrol stations or with a personal tyre pressure gauge. Here's a step-by-step guide:
- Locate the valve stem on each tyre.
- Remove the valve cap.
- Press the tyre pressure gauge firmly onto the valve stem.
- Read the pressure displayed on the gauge.
- Compare the reading to the recommended pressure on the tyre placard.
- If the pressure is too low, add air using an air compressor until you reach the recommended level.
- If the pressure is too high, release air by pressing the pin in the centre of the valve stem.
- Replace the valve cap.
It's recommended to check your tyre pressure at least once a month and before any long trips. Temperature fluctuations can also affect tyre pressure, so it's a good idea to check more frequently during periods of extreme heat or cold.
The Financial Impact of Under-Inflated Tyres: Real-World Examples
The savings from properly inflated tyres can be quite significant. Studies have shown that for every 1 PSI below the recommended pressure, fuel efficiency can decrease by as much as 0.3%. Over time, this adds up. In today's market, where prices in Melbourne for Premium 98 are averaging 227.69 cpl and Unleaded 91 is around 203.77 cpl, even a small improvement in fuel efficiency can translate to substantial savings. Consider also that Unleaded 91 prices are currently 31% higher in Melbourne (203.77 cpl) than in Adelaide (155.59 cpl) which makes tyre pressure even more important for Melbourne motorists.
Beyond Tyre Pressure: Other Fuel-Saving Tips
While maintaining proper tyre pressure is crucial, it's just one piece of the puzzle when it comes to optimising fuel efficiency. Other factors to consider include:
- Driving Habits: Avoid aggressive acceleration and braking. Maintain a steady speed whenever possible.
- Vehicle Maintenance: Ensure your vehicle is properly serviced, including regular oil changes and air filter replacements.
- Reduce Weight: Remove unnecessary items from your vehicle to reduce the load.
- Plan Your Trips: Combine errands into a single trip to minimise cold starts, which consume more fuel.
