What happens

Symptom. Harsh ride, vibration at speed, slow punctures.

Cause. Stiff-sidewall run-flats transmit impacts straight into the rim, and these alloys crack rather than bend.

How to check it

Static checks

Inspect the inner rim edge of every wheel for cracks and hairline splits, not just the face for kerbing. Budget for a set of conventional tyres; most owners switch and the ride improves markedly.

Engine off, ideally on a lift.

The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
