Do EVs Need Higher Tyre Pressures Than Petrol Cars? Quick answer: Often, yes. Electric cars are heavier than comparable petrol cars because of the battery, so many EVs specify higher placard pressures and tyres with a higher load rating. But you never guess — you...

Tyre Pressures for a Fully Loaded Family Road Trip Quick answer: When your car is packed with passengers and luggage, use the higher “laden” or “full load” pressures on your tyre placard — usually a few extra psi in the rear. Set them cold...

Quick answer: A tyre pressure monitoring system (TPMS) warns you when a tyre loses pressure. Direct systems use in-wheel sensors and read actual psi; indirect systems infer pressure from ABS wheel-speed sensors and can be fooled. Both warn late — often only once a...

Quick answer: For Australian 4WD touring, buy a 12V compressor with a high duty cycle (45+ minutes at 40 psi), strong airflow (litres per minute), and a direct-to-battery lead. Single-cylinder units suit lighter setups; twin-cylinder units air up big tyres far faster....

Quick answer: Before you leave the sand and rejoin sealed roads, reinflate your tyres to their normal placard pressure. Driving at highway speed on soft-sand pressures builds dangerous heat and can cause a blowout. Air up at a beachside servo, a dedicated 4WD air...

Quick answer: The four-pounds (4 psi) rule is a tuning method, not a fixed number. Set your tyres cold, drive at highway speed for about an hour, then re-check them hot. A rise of roughly 4 psi means your cold pressure is about right. More than 4 psi means...

Quick answer: Nitrogen leaks a little slower than air and swings less with temperature, but the benefit for an ordinary Australian road car is small — normal air is already about 78% nitrogen. You still have to check your pressures. If it’s free with a...

Quick answer: Underinflated tyres flex too much and build heat, which is the dangerous part — at highway speed that heat can trigger a blowout. Low pressure also wears the tyre’s outer edges, raises fuel use (roughly 0.3% per psi below placard), and makes...

Quick answer: Overinflating your tyres shrinks the contact patch, so they wear out down the centre of the tread, ride harshly, and lose grip — especially braking and cornering in the wet. It also makes the tyre more vulnerable to pothole and impact damage....

Quick answer: Check your tyre pressures at least once a month, and always before a long trip, before towing, or before carrying a heavy load. Check them cold — before driving, or after less than about 2 km — and don’t forget the spare. A tyre pressure warning...
