Seasonal Tyre Maintenance Calendar for Australian Drivers

Unlike Europe or North America, most of Australia never swaps to dedicated winter tyres. Instead, the one set on your car has to cope with 40°C bitumen in January, harsh UV all year, corrugated dirt on a long weekend, and sub-zero mornings in the high country. This calendar turns that into a simple, repeatable routine so nothing gets missed. Use it as the hub for the Refined Autos seasonal guides — each season links to the detailed article. For the fundamentals that apply all year, retailers like mycar cover general tyre care well.

Why does a seasonal calendar matter in Australia?

Tyres degrade on two clocks at once: kilometres driven and time/exposure. Australian conditions push the second clock hard. UV and ozone attack the rubber, heat accelerates ageing and raises running pressure, and big seasonal temperature swings move your cold inflation around. A set calendar means you catch a slow puncture, an ageing sidewall or an alignment problem before it becomes a roadside failure. The legal minimum tread depth across Australia is 1.5 mm in the principal grooves (not the UK’s 1.6 mm), but grip in the wet drops well before that — many makers suggest replacing nearer 3 mm.

What should you check every month, all year round?

Some jobs do not care what season it is. Treat these as your baseline, on top of the seasonal tasks below. Motoring bodies such as the NRMA publish similar year-round tyre checklists.

• Cold tyre pressures — check when tyres have been parked 3+ hours or driven under ~2 km, and set to the placard figure. See how often to check pressures.
• Visual scan — look for cuts, bulges, embedded nails and uneven wear. A bulge means the tyre is finished.
• Spare — a flat spare is useless; check it when you check the others.
• Rotation — every 5,000–8,000 km as a guide; see how often to rotate.

Summer (December–February): heat and holiday loads

This is the hardest season on Australian tyres. Air temperatures over 40°C can push road surfaces past 60°C, and well beyond that in a heatwave. Heat softens rubber, raises pressure by roughly 1–2 psi per 10°C, and ages the compound faster — so an underinflated, overloaded or damaged tyre is at its highest blowout risk now.

• Set pressures cold, early morning — never bleed air from hot tyres to “fix” a high reading.
• Use the placard’s loaded figure when the car is packed for holidays.
• Park in shade where you can; prolonged sun ages sidewalls.
• Do a full summer road-trip prep before any big drive.

Autumn (March–May): reset and pre-trip prep

Autumn is the practical time to reset after summer’s punishment and get ahead of the Easter and school-holiday travel peaks. Cooler air means your summer pressures will now read low, so re-set to the placard. It is also the sensible window for a wheel alignment and balance check if the car pulled, wandered or vibrated over summer.

• Re-check and re-set cold pressures as temperatures drop.
• Inspect tread depth and wear pattern; book an alignment if wear is uneven.
• Check the tyre age using the DOT date code (WWYY). Many makers suggest inspecting tyres over 5 years old and replacing around 10 years regardless of tread.

Winter (June–August): cold mornings and the alpine rule

For most of Australia, “winter” just means colder mornings — and colder air means lower pressure. Expect the pressure-warning light to appear on frosty starts; top up to the placard rather than ignoring it. See how cold mornings affect pressure and grip.

If you drive into declared alpine areas, the rules change. In NSW’s Kosciuszko National Park, 2WD vehicles are generally required to carry chains over the declared season, and in Victoria’s alpine resorts (including Mt Buller) all vehicles are typically required to carry diamond-pattern chains every day of the declared season. These rules change — confirm with NSW National Parks, Alpine Resorts Victoria or the resort before you go. Details: snow chain requirements and do you need winter tyres in Australia?

Spring (September–November): recovery and the big-trip check

Spring is for catching anything that developed over winter and preparing for the summer driving season. Rising temperatures will push your pressures up again, so re-set them. This is also the time to decide whether tyres will safely last another summer or should be replaced now.

• Re-set cold pressures for warmer weather.
• Review the six replacement signs — see when to replace tyres.
• Book balancing or alignment before holiday road trips, not during them.

Frequently asked questions

How often should I actually check tyre pressure?

At least monthly, and before any long trip, always when the tyres are cold. Pressure naturally moves with temperature, so the reading that was right in July will be low by December.

Do I need different tyres for summer and winter in Australia?

For the vast majority of drivers, no. A good all-season or quality touring tyre handles Australian conditions year-round. Dedicated cold-weather tyres only make sense for regular alpine or high-country driving.

When should I replace a tyre regardless of tread?

If it shows a sidewall bulge, deep cracking, cord showing, or is around 10 years old from its DOT date, replace it — tread depth alone is not the whole story.

Does the calendar change for a 4WD or caravan?

The timing is the same, but towing and off-road use add load and heat, so inspect more often and always use loaded pressures when towing.
