Should You Replace All Four Tyres at Once?
Do you need to replace all four tyres, or just the worn ones? A Cranbourne West specialist explains.
When you can replace fewer
On most front- or rear-wheel-drive cars you can replace tyres in pairs (always across an axle, never just one) as they wear. The key is matching the new tyres’ type and keeping tread depths reasonably even side to side.
When you replace just two, the new (deeper-tread) tyres usually go on the rear for stability, even on a front-drive car.
When all four is the safer call
On AWD and 4WD vehicles, the manufacturer often requires all four tyres to be the same type and within a small tread-difference tolerance — mismatched tyres can damage the AWD system (the diff/coupling). So AWD owners often do need all four (or careful tread-matching).
We’ll advise honestly for your car — pairs where it’s fine, all four where it protects your driveline.
Not sure which is right for your car?
Every car and situation is different — the best choice depends on your exact vehicle, how you use it and its condition. We give you straight, no-pressure advice based on what’s actually best for you, not what makes us the most.
