When To Replace Your Tyres: Guide To Tyre Safety and Maintenance 

Tyre Safety
Are your tyres safe enough to keep driving on?
Worn or uneven tyres are one of the top causes of poor handling, long stopping distances, and unexpected blowouts—especially in wet weather.

But many drivers don’t realise their tyres need replacing until it’s too late.

How Do I Know When I Need New Tyres?

Look for shallow tread, cracks in the sidewall, or any signs of bulging. Even if your tyres appear fine at a glance, anything under 1.5mm tread depth is no longer road legal in Australia.

If your car feels like it’s not gripping as well, or you're skidding more easily in the wet, it's a good idea to get them checked.

Another sign to watch for is uneven wear, which may indicate an issue with alignment or suspension. You might also notice your car feels less stable when turning, or that the ride is rougher than usual.

We often get asked, “How do I know when I need new tyres?” The best way is to have them inspected by a professional, who can check the wear pattern, depth, age, and overall condition.

But you can also do a quick check yourself by using the tread wear indicators in the grooves of your tyre. If the tread is worn down to these indicators, it’s definitely time to replace.

Choosing the Right Tyres

Another common question we often get asked when replacing tyres is “What tyre brands should I choose?”

We stock a wide range to suit all types of vehicles and budgets, including trusted names like Michelin, Bridgestone, Pirelli, Goodyear, and more.

We can help you pick the right option based on how and where you drive.

City drivers might prefer something built for comfort and fuel efficiency, while country or high-performance drivers may benefit from all-terrain or sports options. Choosing the right tyre type can also impact your vehicle’s braking performance, noise level, and fuel economy.

Why Tyre Rotation Also Matters

Keeping your tyres healthy not only means replacing them, it also means rotating them regularly.

Rotating your tyres every 10,000km helps them wear evenly, which not only extends their life but keeps your ride smooth and your handling balanced. It’s a simple job that can prevent one pair of tyres from wearing out far sooner than the others.

Many drivers skip this step, but it makes a noticeable difference—especially in front-wheel drive vehicles where the front tyres wear out faster.

When to Get Your Wheels Balanced

Tyre health also relies on wheel balancing. If your steering wheel shakes at higher speeds, you may have an unbalanced wheel.

This issue can affect your vehicle’s ride comfort, and over time, it can cause additional wear on suspension components.

Balancing removes those small vibrations and also prevents premature tyre wear.

You should get your wheels balanced every time you get new tyres, after hitting a pothole, or any time you feel vibration or see uneven tread wear.

It’s an easy, cost-effective way to maintain a smoother drive and extend tyre life.

Don’t Forget Tyre Pressure and Wheel Alignment

Tyre Pressure and Wheel Alignment
Underinflated tyres lead to poor fuel economy and overheating, while overinflated ones can wear out the centre tread quickly.

Check your tyre pressure every 2–4 weeks—you’ll usually find the correct pressure on a sticker inside the driver’s door. Staying on top of pressure helps your tyres last longer and keeps you safer on the road.

Wondering if you’ve got any wheel alignment problems?

If your car is pulling to one side, or your steering feels off-centre, it could mean your wheels aren’t aligned. Misalignment can cause tyres to wear out much faster and affect your car’s handling and safety.
