Key Takeaways
Electric car tyres wear 20 to 30 per cent faster due to battery weight and instant torque.
Always replace tyres when the tread depth drops below 3 mm for summer or 4 mm for winter.
A tyre sidewall damaged by a curb compromises structural integrity and requires immediate replacement.
The physical age of the car tyre dictates replacement even if the tread looks perfectly fine.
Vehicles equipped with air suspension must be placed in Maintenance Mode before lifting.
Wondering exactly when to change the tyres on your electric vehicle in Australia?
As an EV driver in Australia, you should replace your tyres every 30,000 to 60,000 kilometres, or immediately if the tread depth falls below 3 mm. Because electric vehicles generate instant torque and carry heavy battery packs, their tyres experience significantly more friction than those of traditional cars.
Monitoring your tread depth, checking for uneven inner wear, and inspecting the sidewalls for curb damage will ensure you maintain maximum battery range and optimal driving safety.
How Long Do Electric Vehicle Tyres Actually Last?
Electric vehicle tyres typically last between 30,000 and 60,000 kilometres. This lifespan is roughly 20 to 30 per cent shorter than tyres on a comparable combustion engine car due to the extreme physical demands of electric mobility.
Understanding how long tyres last requires looking at the unique physics of an electric powertrain. The lifespan of your tyres is heavily influenced by three distinct factors:
Battery Weight: The massive high-voltage battery pack of a battery electric car adds significant weight to the chassis. This extra mass presses the rubber harder into the asphalt, increasing daily friction and heat generation.
Instant Torque: Electric motors deliver maximum power instantly. Aggressive acceleration off the line acts like sandpaper against the tread. A heavy luxury SUV driven with a heavy foot can consume a set of tyres in just 25,000 kilometres.
Regenerative Braking: The constant drag of the electric motors slowing the car down also adds continuous friction to the contact patch.
How Can You Tell if Your Tyres Need Replacing?
You must replace your tyres when the tread depth reaches 3 mm for summer driving or 4 mm for winter driving. You should also replace them if you notice severe uneven wear along the inside edge of the rubber.
In Australia, the legal minimum tread depth varies by state but is typically around 1.5–1.6 mm. Pushing a heavy electric vehicle to this absolute limit is highly dangerous. The excess weight requires substantial tread to evacuate water and prevent hydroplaning on wet highways. Regularly inspecting your rubber ensures you catch critical wear before it becomes a safety hazard:
The Coin Test: Insert a 20-cent coin into the main grooves. If the golden edge is visible, your tread has dropped below 3 mm and requires replacement. (Resource: Wheel size)
Hidden Inner Wear: The instant torque can cause slight suspension misalignments over time. Your tyres might look perfectly healthy on the outside while the inside edge is worn completely down to the structural cords. Always turn the steering wheel fully to one side to inspect the entire width of the front tyres.
What Happens if the Tyre Sidewall is Damaged by a Curb?
If you notice a tyre sidewall damaged by a curb, you must replace the tyre immediately. The sidewall of an electric vehicle tyre bears extreme structural loads and cannot be safely repaired.
Electric vehicles use specially reinforced high-load tyres to support the heavy chassis. When you strike a curb, the impact crushes the internal cords of the sidewall. A deep gouge or a visible bulge indicates catastrophic structural failure. Driving on a compromised sidewall at highway speeds risks a sudden blowout.
You must also monitor the age of the car tyre.
Rubber naturally degrades, oxidises, and hardens over time. Even if the tread looks deep and there is no visible curb damage, you should replace any tyre that is more than six years old. Hardened rubber loses its ability to grip the road, increasing your braking distance drastically.
FAQ
Q: Do I need special tyres for my electric vehicle?
A: Yes. You must purchase EV-specific tyres that feature a high-load capacity rating. These tyres feature reinforced sidewalls to manage the battery weight and utilise specialised rubber compounds to reduce rolling resistance and preserve your WLTP range.
Q: Why do electric vehicle tyres have foam inside them?
A: Electric vehicles lack engine noise to mask the sound of the road. Premium EV tyres include a thick layer of acoustic polyurethane foam glued to the inner liner to absorb vibrations and keep the cabin whisper quiet.
Q: When should you switch to winter tyres?
A: If you drive in alpine regions during winter, switch to winter tyres when temperatures consistently drop below 7 degrees Celsius. Winter rubber compounds remain soft in freezing conditions to provide necessary traction for the heavy electric chassis.
Q: How Long Are Tyres Covered Under XPENG Warranty?
A: Under the XPENG limited warranty — from one of Australia's leading Chinese EV brands — new tyres are classified as consumable parts and are covered for a period of 12 months or 20,000 kilometres.
We strongly suggest that all tyre replacements and wheel balancing be performed by an authorised XPENG Service Centre or a certified facility, as tyre replacement affects broader vehicle systems, including the high-voltage battery and the dual-chamber air suspension.
Any improper repairs, unauthorised modifications, or failure to use the correct lifting procedures (such as ignoring the Maintenance Mode) will compromise your vehicle and are excluded from warranty coverage.
