Tyre Care Before Road Trips: Check These First

A loaded car, hot roads and hours at highway speed will expose tyre problems quickly. Tyre care before road trips is not about making your vehicle perfect - it is about spotting the issues that can turn a good weekend away into a puncture on the side of the road, uneven tyre wear or a long wait for help.

For Hunter drivers heading towards the coast, the vineyards, the bush or interstate, a quick check a few days before leaving gives you time to fix what needs fixing. Do not leave it until the driveway departure when the car is packed and everyone is ready to go.

Start with cold tyre pressures

Pressure is the first thing to check because it affects safety, tyre life, fuel use and how the vehicle handles when loaded. Check pressures when the tyres are cold, ideally before the car has been driven or after it has been parked for several hours. Driving even a short distance warms the air inside and can give a misleading reading.

Use the pressure shown on your vehicle’s tyre placard, usually found inside the driver’s door opening, glovebox or fuel flap. It is set by the vehicle manufacturer for your car, SUV, ute or van. The number moulded into the tyre sidewall is the tyre’s maximum pressure, not your normal running pressure.

If you are taking extra passengers, towing a caravan or trailer, or filling the boot with camping gear and tools, check the placard for its loaded or towing pressure recommendation. A ute that feels fine around town can need a different pressure when it is carrying a full load. The same applies to 4WDs heading onto gravel or unsealed roads - pressure changes may be appropriate for the conditions, but start with the manufacturer’s advice and reinflate before returning to sealed roads.

Check every tyre, including the spare. A spare that has been ignored for years is no help when you need it.

Look at the tread, not just the pressure

Tyres need enough tread to clear water and maintain grip in wet conditions. The legal minimum tread depth is 1.5 mm across the main tread area, but waiting until a tyre reaches that point is not a great road-trip plan. Wet-weather grip drops as tread gets lower, particularly on worn tyres that are also carrying a heavy load.

Most tyres have tread-wear indicators built into the grooves. These small raised bars sit across the groove and show when the tyre is approaching the minimum depth. If the tread is level with those bars, the tyre needs replacement. Check the inside and outside edges as well as the centre, as uneven wear often reveals a pressure, alignment or suspension issue.

A tyre that is worn mostly along both shoulders may have been run underinflated. Excess wear through the centre can point to overinflation. Wear concentrated on one edge, or a feathered feel when you run your hand across the tread, can indicate wheel alignment problems. A road trip will not cure uneven wear - it will usually make it worse.

Check for damage that can become a failure

Walk around the vehicle and inspect the sidewalls and tread closely. Look for nails, screws, cuts, cracking, bulges, exposed cords or deep stone damage. Sidewall bulges are especially serious because they can mean internal tyre damage. That tyre should not be trusted for a long drive, even if it is still holding air.

Do not pull out a nail or screw before getting advice. If it is helping seal the hole, removing it can leave you with a flat tyre straight away. A workshop can inspect whether the puncture is repairable and carry out the repair properly. Some punctures can be repaired safely, while damage near the sidewall, a large hole or damage caused by driving flat may mean replacement is the safer option.

Cracking deserves attention too. Fine surface cracking can develop as tyres age and spend time in sun and heat. It does not always mean immediate failure, but deep cracks, widespread weathering or tyres of unknown age are worth having checked before a long run.

Do not forget wheel balance and alignment

If the steering wheel shakes at highway speed, the vehicle pulls to one side, or you have noticed unusual vibration through the seat, book an inspection before you leave. These signs may be caused by wheel balance, wheel alignment, damaged tyres or other vehicle issues.

Wheel balancing helps the tyre and wheel rotate smoothly. An imbalance may seem minor on local roads but becomes tiring and uncomfortable at 100 km/h, and can contribute to irregular tyre wear. Wheel alignment makes sure the tyres point and track as they should. It can improve steering feel and help protect a new set of tyres from wearing out too soon.

There is a trade-off here: not every car needs an alignment before every holiday. If it drives straight, the steering wheel sits centred and the tyres are wearing evenly, a basic tyre inspection may be all that is needed. But if you have hit a pothole, kerb or rough track recently, or you can see uneven wear, it is worth checking properly.

Give the spare tyre a real check

Many drivers know they have a spare but have never looked at it. Before a trip, find out whether your vehicle has a full-size spare, a space-saver spare, a tyre repair kit or no spare at all. Each option changes what you can do when a puncture happens.

A full-size spare is generally the most useful option for longer travel, provided it is in good condition and inflated. A space-saver is usually intended for temporary, limited-distance use and may have a lower speed limit. A repair kit can be handy for a small tread puncture, but it will not fix every problem, including sidewall damage or a split tyre.

Make sure the jack, wheel brace, locking-wheel-nut key and any tyre repair kit are actually in the vehicle. If you are unsure how to use them, learn before you are stuck beside a busy road or on a dark country stretch. It is also sensible to check that the spare can be removed from its carrier, especially on utes and 4WDs where it sits underneath the vehicle.

Match your tyres to the trip ahead

A holiday drive is not always just highway kilometres. You may be towing to a campsite, carrying bikes, travelling with a full family load or taking a 4WD onto gravel roads. Your tyres need to be suitable for the work you are asking them to do.

For everyday passenger vehicles, matching tyre size, load rating and speed rating to the manufacturer’s requirements is the safest approach. For SUVs, utes and 4WDs, consider how much sealed-road driving, towing and off-road travel is really planned. An aggressive all-terrain tyre can offer more confidence on rougher surfaces, but it may be noisier and wear differently on bitumen. A highway-focused tyre can be a better fit for drivers who spend nearly all their time on sealed roads.

If one tyre needs replacing, avoid guessing. Different tread patterns, sizes or levels of wear across an axle can affect handling. A tyre professional can advise whether a single replacement is suitable or whether a pair is the better option for your vehicle and the condition of the remaining tyres.

Plan the check early enough to act

The best time for tyre care before road trips is several days before departure. That gives you room to arrange replacement tyres, repairs, balancing or rotation without disrupting your plans. It also avoids the rush that often happens before long weekends, school holidays and Christmas travel.

A quick pre-trip inspection is especially worthwhile if your vehicle has been sitting unused, you have recently bought a second-hand car, or the tyres are approaching the end of their life. Tyres can lose pressure slowly without being obvious, and problems that are manageable around Rutherford can become more serious once you are well outside town.

If anything looks worn, damaged or uncertain, get it checked before loading up. A fast tyre inspection now is usually cheaper, safer and far less frustrating than losing a day of your trip to a preventable tyre problem.
