Tyre Pressures

How often should you check tyre pressures in Australia? At least monthly, before every long trip, and always cold. Here’s the full schedule — plus the spare.

Overinflated tyres wear out in the centre, ride harshly and grip worse — especially in the wet. Here’s what overinflation does and the pressure to follow instead.

Underinflated tyres build heat, wear on the edges, burn more fuel and can blow out. Here’s what low tyre pressure does — and why it’s the dangerous one.

Nitrogen tyre fill leaks slower and swings less with heat — but for a road car the benefit is small and you still must check pressures. Is it worth paying for?

The 4 psi rule tells you if your off-road tyre pressure is right: set cold, drive an hour, then check the hot rise. Here’s how to use it in Australia.

After a beach drive, reinflate to your placard pressure before sealed roads. Here’s where to find air in Australia and why low tyres fail at highway speed.

How to choose a portable 12V air compressor for Australian 4WD touring: duty cycle, airflow, twin vs single, tank options and matching one to your tyres.

How tyre pressure monitoring systems work — direct vs indirect TPMS, why they warn late, when they lie, and what Australian drivers should know in 2026.

A cold morning drops tyre pressure about 1 psi per 5–6°C, tripping the warning light on healthy tyres. Here’s when it’s just the cold and when it’s a real leak.
