Your car’s tyres are crucial to its overall safety and performance, but many drivers overlook the warning signs of tyre wear and damage. Knowing when to replace your tyres is essential for maintaining optimal grip, fuel efficiency, and a safe driving experience. At Cars4Us, we’re committed to helping drivers stay informed and safe on the road. Here are five warning signs that it’s time to change your car tyres.
1. Tread Depth is Below the Legal Limit
One of the most obvious signs that your tyres need replacing is low tread depth. The legal minimum tread depth in Australia is 1.5mm, but experts recommend replacing tyres once the tread reaches 3mm to maintain optimal performance, especially in wet conditions. Tyre tread helps provide grip on the road, and if it’s worn down, your car’s handling, braking, and traction are severely compromised.
How to Check:
- Use a tread depth gauge or the ‘coin test’ by inserting a coin into the tread. If you can see the top of the coin, your tread is too low.
- Many tyres also come with tread wear indicators—small raised bars within the grooves. If these bars are level with the tread, it’s time to replace your tyres.
2. Cracks, Bulges, or Cuts on the Tyre Sidewall
Regularly inspecting the sidewalls of your tyres is important. Look for visible cracks, bulges, or cuts, which could indicate that the tyre is structurally compromised. Bulges can form due to impact damage from potholes or curbs, while cracks can appear as tyres age or when exposed to extreme weather conditions. Driving on tyres with these issues increases the risk of a blowout, which can be extremely dangerous.
What to Look For:
- Cracks or splits on the sidewall.
- Bulges or blisters, which indicate internal damage.
- Visible cuts or punctures that could lead to a flat tyre.
3. Uneven Tread Wear
Uneven tread wear is a sign that your tyres are not making proper contact with the road. This can be caused by a variety of factors, including improper wheel alignment, unbalanced tyres, or worn suspension components. If you notice one side of the tyre wearing down more quickly than the other, or ‘bald spots’ in specific areas, it’s time to replace your tyres and have your car inspected for underlying issues.
How to Spot It:
- Inspect your tyres for inconsistent tread wear across the surface.
- Pay attention to whether the inner or outer edges are more worn than the centre.
- Uneven wear patterns can also result in a noisy or uncomfortable ride.
4. Excessive Vibration While Driving
It’s normal to experience some vibration while driving, especially on rough roads, but excessive vibration could indicate an issue with your tyres. This may be a sign of an internal tyre problem, wheel imbalance, or suspension issues. If the vibrations are more pronounced when driving at high speeds or through the steering wheel, it’s essential to get your tyres checked and replaced if necessary.
What to Do:
- Pay attention to vibrations while driving, particularly if they seem to get worse over time.
- If the vibration is coming from one side, it could indicate an issue with that specific tyre.
- Have your tyres inspected by a professional to determine whether they need replacing or if there’s an issue with the vehicle’s alignment or balance.
5. Old Tyres or Expired Tyre Age
Even if your tyres don’t show visible signs of damage or wear, they can still deteriorate with age. Tyres naturally lose their elasticity and strength over time, making them more susceptible to cracking, reduced grip, and blowouts. Most manufacturers recommend replacing tyres every 6 to 10 years, regardless of tread depth, to ensure safe driving conditions.
How to Check Tyre Age:
- Look for the DOT code on the tyre sidewall. The last four digits indicate the week and year the tyre was manufactured (e.g., 2219 means the tyre was made in the 22nd week of 2019).
- If your tyres are older than six years, consider replacing them, even if the tread looks fine.
Why Regular Tyre Inspections are Important
Tyres are the only part of your car that makes contact with the road, so their condition directly affects your vehicle’s performance and safety. Regular inspections can help identify potential problems before they lead to accidents or breakdowns. Replacing your tyres at the right time ensures better handling, improved fuel efficiency, and reduced risk of tyre failure on the road.
