Tyre Pressure & Fuel Savings: Aussie Driver's Guide (November 2025)

With fluctuating petrol prices continuing to impact household budgets across Australia, every little bit of fuel efficiency counts. While many focus on driving habits, a frequently overlooked factor is tyre pressure. Ensuring your tyres are correctly inflated can significantly improve your fuel economy and save you money at the pump. This guide, brought to you by FuelRadar, will explain the connection between tyre pressure and fuel consumption, providing practical tips to optimise your vehicle's performance and your wallet.

The Link Between Tyre Pressure and Fuel Efficiency

When tyres are underinflated, they have a larger contact area with the road. This increased rolling resistance requires your engine to work harder to maintain speed, resulting in higher fuel consumption. Think of it like riding a bicycle with flat tyres – it requires much more effort to pedal. Conversely, correctly inflated tyres minimise rolling resistance, allowing your vehicle to glide more efficiently and use less fuel.

Understanding Recommended Tyre Pressures

The correct tyre pressure for your vehicle is not a universal number. It's crucial to consult your vehicle's owner's manual or the tyre placard, usually located on the driver's side doorjamb or inside the fuel filler flap. This placard provides the manufacturer's recommended tyre pressure, typically measured in pounds per square inch (PSI) or kilopascals (kPa). Adhering to these recommendations is vital for optimal fuel efficiency, tyre life, and overall safety.

The Impact of Underinflation

Driving with underinflated tyres can have several negative consequences, including:

• Reduced Fuel Economy: As mentioned earlier, underinflation increases rolling resistance, leading to higher fuel consumption.
• Premature Tyre Wear: Underinflated tyres tend to wear more quickly along the edges.
• Compromised Handling: Underinflation can affect your vehicle's handling, making it less responsive and increasing the risk of accidents.
• Increased Risk of Blowouts: Underinflated tyres are more susceptible to overheating and blowouts, especially during hot weather or when carrying heavy loads.

Checking and Maintaining Tyre Pressure: A Simple Routine

Regularly checking your tyre pressure is a simple yet crucial maintenance task. Here’s how to do it correctly:

1. Invest in a reliable tyre pressure gauge: Digital gauges offer more accurate readings than traditional stick gauges.
2. Check your tyres when they are cold: Ideally, check them before driving or after the vehicle has been parked for at least three hours. Driving heats the tyres and increases the pressure, leading to inaccurate readings.
3. Remove the valve cap and firmly press the gauge onto the valve stem: Ensure a good seal to get an accurate reading.
4. Compare the reading to the recommended tyre pressure on the placard: Inflate or deflate the tyre as needed.
5. Replace the valve cap: This helps prevent dirt and moisture from entering the valve stem.
6. Check all tyres, including the spare: A properly inflated spare tyre is essential in case of a flat.

Aim to check your tyre pressure at least once a month and before any long trips. Remember that tyre pressure can fluctuate with temperature changes, so adjust accordingly.

Fuel Price Insights and How FuelRadar Can Help

Staying informed about fuel prices is another crucial aspect of saving money on motoring expenses. As of today, November 2025, fuel prices vary significantly across Australian capital cities. For example, Unleaded 91 prices are currently 14.5% higher in Brisbane (195.82 cpl) than in Sydney (171.01 cpl). Premium 98 prices also show substantial differences, with Darwin (223.55 cpl) being 14.6% more expensive than Sydney (195.05 cpl). Diesel prices are also noteworthy, with Canberra (193.9 cpl) being more expensive than Adelaide (179.73 cpl). Interestingly, Adelaide currently offers some of the most competitive fuel prices overall.

To help you navigate these price fluctuations and find the cheapest fuel near you, FuelRadar provides real-time fuel prices across Australia. Whether you're in Sydney, where Premium 95 (187.92 cpl) costs 9.9% more than Unleaded 91 (171.01 cpl), or Brisbane, where motorists can save 1.3% by choosing E10 (193.21 cpl) over Unleaded 91 (195.82 cpl), FuelRadar empowers you to make informed decisions and save money every time you fill up.

Optimising Your Driving Habits for Fuel Efficiency

While maintaining proper tyre pressure is essential, adopting fuel-efficient driving habits can further enhance your savings. Consider these tips:

• Drive smoothly: Avoid rapid acceleration and hard braking.
• Maintain a steady speed: Use cruise control on highways to maintain a consistent speed.
• Anticipate traffic: Look ahead and anticipate changes in traffic flow to avoid unnecessary braking.
• Reduce idling: Turn off your engine when stopped for more than a minute.
• Minimise air conditioning use: Using air conditioning increases fuel consumption, so use it sparingly.
• Remove unnecessary weight: Extra weight in your vehicle increases fuel consumption.
