Do I Need New Tyres?

It is difficult to predict when a tyre will need replacing – tyre lifespan and mileage depends on its design, driver habits, climate, road conditions and the level of tyre maintenance applied.

However, keep in mind that after 5 years in use, you should take your vehicle for a tyre inspection at least once per year, and if your tyres haven’t been replaced in 10 years, you should replace them even if they have not been worn down to the tread indicator. Check for the manufacturing date using the DOT number on the sidewall of the tyre.

Things that will ensure that you get more mileage out of your tyres:

  • Maintain your tyres air pressure, alignment and make sure that you regularly check that the wheels of your vehicle are properly balanced – you should check your tyre pressure at least once a month, and your alignment and wheel balancing should be done with every replacement tyre fitment
  • Avoid potholes, driving into kerbs, sharp objects in the road and slow down over speed bumps.
  • Quick starts and emergency braking will increase tyre wear and tear
  • Avoid mixing tyre types on your vehicle
  • Be alert for any change in handling, noise or vibration and consult a professional if any of these occur
  • Don’t use summer tyres on snow and ice
  • Don’t re-inflate a tyre that has been run flat, or run seriously under-inflated

You should replace a tyre if

  • The tread is worn below the recommended tread depth
  • There is any damage to the sidewall
  • You have a hole in the tread that is more than 6mm in diameter
  • The edge of the tyre that sits on the wheel (the bead) is damaged or deformed

Inspect your tyres regularly and look for

  • Uneven tread wear
  • Shallow tread
  • Any nails, stones
  • Any damaged areas
  • Damaged valve caps

Pay attention to the feel of your car as you drive – a rough ride may indicate tyre damage or excessive wear. If you notice any vibration or other issue while driving – reduce your speed, pull over safely and inspect your tyres.

 

If your inspection reveals anything that you are unsure of, take your vehicle to a tyre dealer for advice.

What To Do If Someone Hits Your Parked Car

Coming back to find your parked car damaged is never fun, but knowing how to respond correctly can save you time, money and stress.

Firstly, understand that getting upset is natural, but taking a deep breath will help you make better decisions. Examine your car thoroughly and document any visible damage, taking multiple photos from different angles, including close-ups of dents, scratches or broken parts, and capturing the surrounding area, such as road signs and markings, for context.

Next, see if you can locate the driver responsible. Sometimes, people leave a note with their contact information and insurance details. If there’s no note, look for witnesses nearby who may have seen what happened. You can also check for CCTV from nearby businesses, homes or on the street, as some areas have coverage. If you’re unsure, consider contacting the local council to find out whether cameras are in place that might have captured the accident.

If the driver didn’t leave a note, or if they did but are unresponsive or the information they provided seems incorrect, contact the police to report the accident and provide all the information you have, including photos, footage and witness statements. Be sure to request a copy of the police report, as it can be useful when dealing with insurance.

If you’re still having a hard time getting a hold of the at-fault driver and therefore cannot claim directly through their car insurer, it’s time to lodge a claim with your own insurance provider, if you have one. Provide them with as much information as possible, including the police report. From there, your insurer can determine whether your coverage, along with the information you have, will cover the damage to your car.

If your car insurer happens to find information about the at-fault driver and is able to have them lodge a claim so the costs of the damage are recoverable, you can contact Carbiz for a replacement car while your car is being repaired or until it’s been deemed a total loss. This ensures you’re not left without a car during this time, giving you peace of mind and the ability to keep your life moving.

What It Means When Your Car Is Declared A Write-Off After An Accident

Updated 6 October 2026.

When an insurer declares a car a write-off, it has assessed the vehicle as a total loss under the policy. The damage may make repairs unsafe, or the cost of repairing the car may make a repair uneconomical. A write-off does not always mean the car is visibly destroyed.

How is a write-off decision made?

The assessment can take account of the vehicle's value, repair costs, salvage value and the policy terms. There is no single repair-cost percentage that determines every write-off across Australia. Ask the insurer for its assessment and the basis for its decision.

A total-loss insurance decision and a vehicle's written-off registration category are related but different matters. Whether a car can return to the road depends on the damage classification and the rules of the relevant state or territory.

Statutory and repairable write-offs

  • Statutory write-off: the vehicle meets specified damage criteria and cannot be re-registered for road use.
  • Repairable write-off: repairs may be technically possible, but the vehicle has been assessed as uneconomical to repair. This label does not itself authorise repairs or guarantee re-registration.

Requirements vary across Australia. In NSW, an eligible written-off light vehicle needs an Authorisation to Repair from Transport for NSW before work begins. Only limited applications are considered, and vehicles with statutory write-off damage are excluded. Approval, compliant repairs and the required inspections are separate steps.

What happens to your insurance payout?

The settlement depends on your cover and circumstances. It may be based on an agreed value, a market value or a replacement-vehicle benefit if your policy provides one. An excess, outstanding premium or finance arrangements may affect the amount you receive. Ask for a written breakdown before accepting the settlement.

Keep the assessment, photographs, policy documents and correspondence together. If you disagree with the valuation, provide relevant evidence and use the insurer's complaints process. See AAMI's explanation of total-loss claims for an insurer's example; your own policy determines your cover.

Getting around after a not-at-fault accident

If you need a replacement vehicle, tell Carbiz that your car has been declared a write-off. Eligibility, vehicle availability, the hire period and the terms of the agreement need to be confirmed for your circumstances. A write-off does not automatically entitle everyone to unlimited hire.

Contact Carbiz to discuss your accident replacement vehicle options. For a practical checklist, read what to do after receiving a write-off decision.
