27 Feb 2025

As a car owner, it's important to keep your vehicle in top condition to ensure your safety and the longevity of your car. One crucial aspect of car maintenance is replacing your tyres when they are worn out. But how do you know when it's time to change your car tyres? Keep reading to find out how often you should change your car tyres and the factors that can affect tyre wear.

How to Know When to Change Your Tyres

Knowing when to change your tyres is essential for maintaining road safety and ensuring optimal performance. While there’s no one-size-fits-all answer, several key factors can help you determine when it’s time for new tyres. From visible signs of wear to environmental conditions and driving habits, it's important to recognise the warning signs before your tyres become a hazard. Below, we’ll explore some of the most reliable indicators to help you decide when your tyres need replacing. Here is when to change your car tyres based on tread depth, age, kilometres driven, driving habits, and environmental factors.

Tyre Tread Depth

The most common way to determine when to change your tyres is by checking the tyre tread depth. Most countries' legal minimum tread depth for car tyres is 1.6mm. However, many experts recommend replacing your tyres when the tread depth reaches 3mm to ensure better grip and safety on the road.

You can use a tyre tread depth gauge or a coin to check the tread depth of your tyres. Place the gauge or coin into the grooves of the tyre and measure the distance between the base of the groove and the top of the tread. If the distance is less than the recommended minimum, it's time to replace your tyres.

Tyre Age

In addition to tread depth, the age of your tyres can also affect their performance and safety. Tyres have a limited lifespan, and even if they have plenty of tread left, they can become unsafe due to age-related issues such as cracking, bulging or other types of damage.

The lifespan of tyres can vary depending on a range of factors, such as the quality of the tyres, the driving conditions, and the storage conditions. As a general rule of thumb, tyres should be replaced every 6 to 10 years, regardless of their tread depth.

To determine the age of your tyres, look for the DOT code on the tyre's sidewall. The last four digits of the code represent the week and year that the tyre was manufactured. For example, a tyre with the code "3019" was manufactured in the 30th week of 2019.

Distance Driven

You can also gauge when to change your tyres based on the kilometres you’ve driven. For the average drive with a typical driving style, new tyres can last anywhere from 25,000 to 50,000 kms. However, keeping an eye on the physical state of the tyres will give you a good indicator. 

Driving Habits

Your driving habits can also affect the lifespan of your tyres. If you frequently drive on rough or poorly maintained roads, your tyres are likelier to wear out faster than if you mostly drive on smooth roads. Similarly, if you frequently drive at high speeds or brake hard, your tyres will wear out faster than if you drive at a steady pace.

To prolong the life of your tyres, try to avoid harsh driving habits whenever possible. Drive steadily, avoid sudden stops and starts, and avoid rough roads whenever possible.

Environmental Factors

Environmental factors can also affect the lifespan of your tyres. Exposure to sunlight and extreme temperatures can cause the rubber to degrade and crack over time. Similarly, exposure to chemicals and other pollutants can also damage your tyres.

To protect your tyres from environmental factors, try to park your car in a garage or other covered area whenever possible. If you must park your car outside, use a tyre cover to protect your tyres from sunlight and other elements.

How Often Should You Change Your Tyres? FAQs

Q: How can I tell if my tyres are worn?

A: You can check your tyre tread depth using a tyre tread depth gauge or a coin. Place the gauge or coin into the grooves of the tyre and measure the distance between the base of the groove and the top of the tread. If the distance exceeds the recommended minimum, it's time to replace your tyres. Additionally, you can look for signs of damage, such as cracks, bulges, or punctures on the tyre's surface. If you notice any of these signs, you should replace your tyres immediately.

Q: Can I replace just one tyre, or do I need to replace all four tyres?

A: It is generally recommended to replace all four tyres at once to ensure even wear and performance. However, if one tyre is significantly more worn or damaged than the others, you may be able to replace just that tyre. Consult with a tyre specialist to determine the best course of action for your specific situation.

Q: Can I extend the life of my tyres?

A: Yes, you can extend the life of your tyres by maintaining proper tyre pressure, driving at a steady pace, avoiding sudden stops and starts, avoiding rough roads whenever possible, and parking your car in a covered area to protect your tyres from environmental factors. Regular maintenance, such as rotating your tyres and checking your alignment, can also help prolong the life of your tyres.

Q: How long do tyres usually last?

A: The lifespan of tyres can vary depending on a range of factors, such as the quality of the tyres, the driving conditions, and the storage conditions. As a general rule of thumb, tyres should be replaced every 6 to 10 years, regardless of their tread depth. However, if you notice any signs of damage or wear, you should replace your tyres immediately.

Q: Can I drive on my tyres even if they are worn?

A: Driving on worn tyres can be dangerous as they have reduced grip on the road, leading to poor handling and longer stopping distances. Additionally, worn tyres are more prone to punctures and other types of damage. It is important to replace worn tyres to ensure your safety on the road.
