Tyres are one of the most important parts of your car — they’re the only thing between you and the road. Worn-out or damaged tyres can affect handling, braking, and overall safety. But how do you know when it’s time to replace them? Here’s a simple guide to help you spot the signs before it’s too late.
1. Check the Tread Depth
The tread on your tyres provides grip on wet and dry roads. In Australia, the legal minimum tread depth is 1.5mm, but it’s safer to replace tyres when they reach 3mm.
- How to check: Use a tread depth gauge or the 20-cent coin test — insert a 20-cent coin into the tread; if you can see the top of the coin, it’s time for new tyres.
Low tread reduces traction, increases stopping distance, and can cause hydroplaning in wet conditions.
2. Look for Visible Cracks or Bulges
Tyres degrade over time, and exposure to sunlight, heat, and road conditions can cause cracks in the sidewalls. Bulges or blisters are even more dangerous.
- Cracks: Small surface cracks are a warning sign that the rubber is weakening.
- Bulges: Usually caused by internal damage, like hitting a pothole. Bulges can lead to sudden tyre failure.
Any cracks or bulges should be checked by a professional immediately.
3. Uneven Tyre Wear
Tyres should wear evenly across the tread. If one area is more worn than others, it could indicate:
- Incorrect wheel alignment
- Imbalanced tyres
- Suspension problems
Uneven wear not only reduces tyre life but can also affect handling and safety.
4. Tyres Are Old
Even if a tyre looks fine, age matters. Most tyre manufacturers recommend replacing tyres every 6–10 years, regardless of mileage.
- Check the DOT code on the tyre sidewall to find the manufacturing date.
- Old tyres can lose elasticity, become brittle, and fail more easily.
5. Vibration or Noise While Driving
If your car vibrates or produces unusual noise while driving, it could be a tyre issue. Possible causes include:
- Worn or uneven tyres
- Tyre separation or internal damage
Vibrations often increase with speed and can signal that a tyre replacement is needed.
6. Reduced Performance in Wet Conditions
Tyres with low tread or damaged rubber have less grip in wet conditions, increasing the risk of slipping or hydroplaning. If your car feels unstable in rain, check your tyres immediately.
7. Frequent Punctures or Air Loss
If you’re constantly inflating tyres or dealing with punctures, it may be a sign that the rubber is worn or weakened. Continuing to drive on unreliable tyres is dangerous and can cause accidents.
Quick Tips for Tyre Maintenance
- Check tyre pressure monthly — underinflated tyres wear out faster.
- Rotate tyres regularly to ensure even wear.
- Inspect tyres before long trips or during seasonal changes.
- Replace in pairs or all four for better balance and safety.
Safety First
Driving on worn or damaged tyres isn’t just risky — it’s illegal in Australia. Regular inspections and timely replacements protect you, your passengers, and other road users.
Even if your tyres are beyond repair, remember: scrap or old tyres still have value. Many recycling and cash-for-cars services accept vehicles with worn tyres, helping you get cash while disposing of them responsibly.
