Quick Answer
To find your car tyre pressure, check your tyres, the tyre placard on your car, or the owner’s manual. Most passenger vehicles recommend 30–35 PSI when cold. Use your own tyre pressure gauge to check regularly for optimal safety, performance, and fuel efficiency.
Why Tyre Pressure Matters
Ensuring the correct tyre pressures is essential for your car’s safety, fuel efficiency, and handling. Over-inflated or under-inflated tyres can cause uneven wear, reduce traction, and even increase the risk of a blowout. Regularly checking your tyre pressure helps you maintain the best performance on Australian roads.
How to Find Your Car’s Recommended Tyre Pressures
1. Check the Tyres
Many tyres list an inflation range in PSI (pounds per square inch) on the sidewall. However, this is the maximum limit and not necessarily the correct pressure for your car. Use it as a guideline only if other sources are unavailable.
2. Refer to the Tyre Placard
Most cars in Australia include a tyre placard, often found on the driver’s side door jamb or inside the fuel door. This placard specifies the recommended tyre pressures for both normal driving and heavier loads, such as when carrying passengers or luggage.
3. Consult Your Owner’s Manual
Your car’s owner’s manual is another reliable source for the correct tyre pressures. Look in the section about tyre maintenance or specifications. Following the manual ensures you inflate your tyres to the pressure designed for your specific make and model.
Is a General PSI Range OK?
In general, most passenger car tyres are inflated to between 30 and 35 PSI when cold. However, the correct pressure can vary based on your vehicle, tyre size, and load. Always rely on your car’s tyre placard or manual to ensure the correct tyre pressures are used.
Tips for Maintaining Correct Tyre Pressure
- Check Tyre Pressure Regularly
Check your tyre pressure at least once a month and before long trips. Use your own tyre pressure gauge for the most accurate readings, as gauges at petrol stations can be unreliable. - Adjust for Load
If you’re towing a caravan or carrying a heavy load, adjust the tyre pressure as per the recommendations on your tyre placard or in your manual. This ensures safe handling and even tyre wear. - Use a Reliable Gauge
Invest in a good-quality tyre pressure gauge to monitor your tyres at home. Digital gauges are particularly easy to use and provide precise readings. - Account for Temperature Changes
Air pressure can fluctuate with changes in temperature. For example, hot conditions in Australia may slightly increase your tyre pressure after driving. Always check when the tyres are cold for the most accurate result.
Why the Correct Tyre Pressure Matters
Driving with the recommended tyre pressure improves fuel economy, extends tyre life, and enhances your car’s handling. By regularly checking tyre pressure and following your vehicle’s recommended tyre pressures, you’ll stay safer on the road and save money in the long run.
With a little effort, checking and maintaining your tyre pressure regularly will keep your car running at its best while ensuring a safe and smooth ride across Australia’s diverse driving conditions
