Wear, Damage and Diagnosis

Heavier wheels add unsprung and rotating mass plus a stiffer tyre. Here’s whether heavier wheels wear tyres faster, and what really drives the wear.

Storing a car for months? Here’s how to stop the tyres flat-spotting — pressures, cradles, moving the car — and which flat spots are permanent.

Storing a spare set of tyres or wheels? Here’s how to keep them cool, dry and ozone-free in an Aussie garage — upright vs stacked, off the concrete, bagged.

Tread depth isn’t the only reason to replace tyres. Six signs beyond it — age, cracking, bulges, uneven wear, vibration and punctures — explained.

How many kilometres should tyres last in Australia? Realistic ranges for budget, premium, performance, all-terrain and EV tyres — plus why age caps the number.

Vibration at 100km/h is usually wheel balance, but not always. Learn to tell balance from a bent rim, flat spot or worn bearing—and what each fix costs.

Steering-wheel shake points to the front wheels, seat shake to the rear, and shudder only when braking means warped discs. Here’s how to read each symptom.

Tyre road noise that steadily gets louder usually points to uneven wear, a failing wheel bearing or an alignment fault. Here’s how to tell which one, the Australian way.

One tyre wearing faster than the rest points to alignment, skipped rotation, a mechanical fault or uneven pressure. Here’s how to diagnose it before it costs you a full set.
