When Should I Change My Tyres? How To Know When To Replace?

How do you know it’s time to bid farewell to your old tyres and invest in new ones?

Let’s explore the signs that indicate the need for tyre replacement and know when to replace them to keep you safe on the road.

When To Replace Tyres

Tread Depth

One of the most crucial factors in determining whether your tyres need replacing is the tread depth.

For instance, in Australia, the law mandates a minimum tread depth of 1.5mm. If your tyre’s tread depth approaches this recommended threshold, that’s a clear indication that it’s time to replace your tyres.

Insufficient tread depth compromises your vehicle’s ability to maintain proper traction, especially in wet or slippery conditions.

Damage Assessment

Keep an eye out for any cuts, bulges, or cracks on the tyre’s surface. These issues can weaken the tyre’s structure, making it susceptible to a blowout or a sudden flat tyre.

If you notice any visible damage, replace the affected tyre promptly.

Age Considerations

Age plays a significant role in the overall condition of your tyres, even if they haven’t been extensively used.

As a general rule, it’s advisable to have your tyres professionally inspected if they are more than five years old. Beyond the ten-year mark, regardless of their apparent condition, it is highly recommended to replace them.

Over time, the rubber compound in tyres can deteriorate, leading to reduced performance, compromised grip, and an increased risk of tyre failure.

How To Tell If Tyres Need Replacing

Vibration And Imbalance

If you experience a noticeable vibration in your steering wheel or seat while driving, it may be an indication of tyre imbalance or irregular wear.

Imbalanced tyres can adversely affect your vehicle’s stability, resulting in an uncomfortable ride. Address this issue promptly to prevent further damage to your tyres and ensure a smooth, balanced driving experience.

Unusual Noise

Pay close attention to any unusual noises originating from your tyres while driving.

Excessive or abnormal tyre noise can indicate significant wear or damage. The tread pattern on your tyres wears down over time, causing increased road noise. If you notice a sudden change in noise level, it’s advisable to have your tyres inspected.

Altered Handling

Your car’s handling characteristics provide valuable insights into the condition of your tyres.

If you notice changes in the way your vehicle responds, such as increased difficulty steering or reduced grip, it’s important to assess your tyres. Uneven wear, tread loss, or damage can compromise your car’s handling capabilities, affecting its overall performance and safety.

Don’t ignore these warning signs; instead, consult a professional to evaluate your tyres and determine if a replacement is necessary.


As tyres age, they undergo wear and tear, losing their tread depth and compromising their ability to maintain a proper grip on the road. This can lead to reduced traction, longer stopping distances, and increased chance of hydroplaning.

Recognise the signs indicating the need for new tyres and take prompt action for your safety and peace of mind.
