When To Replace Your Tyres

Let's break down what you need to know to replace your tyres with the best set for your driving needs. 

Tyres are an essential part of your vehicle, ensuring your safety and comfort with every drive. They support the body weight of passengers and the car itself. Tyres are also the only parts of your vehicle that touches the ground and stops it from moving.

Tyres are made out of natural and synthetic rubber and are built to last long - but won't last forever. At some point, you will need to replace your tyres.

The question is: When exactly is it time for a tyre change?

When does a tyre need to be replaced?

You have an unrepairable flat or punctured tyre.

A flat tyre is like the measles for drivers. You're bound to experience it at least once. A flat occurs when the tyre no longer has the correct tyre pressure, the air escaping naturally - yet slowly over time, or due to a tyre puncture, and you need to change tyres.

They can be stressful, especially if it is late at night. You have to switch on your hazard lights and wait for roadside assistance if you don't have a spare tyre.

It is possible to perform puncture repairs - but not all the time. If the damage is on the tread area, it still has a chance of repairs. But if your sidewalls are injured, you will need to replace your tyre completely. To make sure you stay safe, get a specialist to inspect the flat tyre after a puncture.

Tread depth is a factor to consider when replacing tyres Tyroola

Your tyre tread has worn down beyond the legal limits.

Tread depth is the measurement from the bottom of your tyre's groove to the surface of the tyre itself, usually up to the most raised part of the tread. The tread is what grips the road, especially when wet. The less tread, the more slippery and unsafe the tyre.

Australian law states that a tyre's tread depth must be at least 1.6 mm deep. Any lower, your tyre is no longer roadworthy. Do not perform any tyre repairs because it is illegal to use and must be replaced.

Your tyre is badly damaged.

Your tyre is exposed to all kinds of obstacles and debris out on the road that can cause severe damage. These include potholes, kerbs, various sharp objects like rocks, branches, small stones, old cans, nails, and more. 

They can puncture, cut or rip your rear and front tyres and even deform their shape. If you spot any large - or even small - visible perforations, get a tyre professional to check your tyre ASAP. Don't forget to unmount the tyre and check inside as well. If it is badly damaged, you need immediately get new tyres fitted.


There are signs of unusual tread wear

There are instances when tyre tread wears down in unusual ways. Either just at the edges, or the centre gets bald first or tyre wear occurs in patches or random chunks throughout the tyre circumference.

These are possible signs that you are driving with too much or too little air; the wrong tyre pressure in general. There could also be underlying issues with your vehicle, like bad wheel balance and suspension problems or more. It's a good idea to get a mechanic to inspect your cars and replace your tyres.

Uneven wear shas a negative impact on the tyre Tyroola

Your tyre is getting older.

When tyres get older, they lose their grip and start to get weaker. 

But how old is "older" exactly? Tyres don't have official expiry dates - only dates when they were manufactured (DOT). The usable life of a tyre is not something that one can predict - no matter the date of production. Tyres experience the most stress when in use, on the trail or the road, and not while sitting in storage.

The following factors affect the life of a tyre much more than its production date: 

  • Your tyre's speed and load rate index
  • Temperature and weather changes
  • Driving styles
  • Differences in tyre pressure
  • High speeds
  • Heavy braking and accelerating
  • Rough roads and terrain
  • Road debris and more.

As a precaution, if your tyres have been in use for more than five (5) years old, get them inspected once a year. You can also check the tyre replacement recommendations of your vehicle manufacturer, which you can find in your owner's manual.

If your tyres are more than ten (10) years old, even if they still look good, rubber deteriorates and cracks with age, so it's best to replace them.


Tip: Replace tyres in complete sets. This way, you don't get uneven wear between tyres, and your car functions more smoothly.


Your tyre does not match your vehicle.

When your vehicle rolled out of the showroom, they came in a set of matching tyres for all four-wheel positions. If, at some point, you end up with different sized tyres or types of tyres (one summer tyre in the front, the other a winter, for example), replace them immediately. It may affect your vehicle's stability and overall driving performance.


The importance of tyre replacement

Getting a new set of tyres improves almost all performance aspects of your car immediately.

But beyond that, it ensures your safety - and those on the road with you.

It's vital to maintain your tyres properly, so you can catch the signs that you might need to change them early and before they potentially harm you - and others on the road.
