2016 BMW Z4 2.0L Petrol · AC60 NAC

A recurring concern is the rear tyre and wheel condition, highlighted by two dangerous MOT failures – a near‑side rear wheel fracture recorded in March 2026 and a rear tyre with exposed ply or cords in March 2023, together with an advisory about excessive wear on the off‑side rear tyre. The most recent MOT on 17 March 2026 passed, indicating the fractured wheel was replaced or repaired, but the history shows that rear‑wheel integrity has required attention within the last three years. The odometer reads 58,843 mi for a 2016 model, equating to roughly 5,900 mi per annum – well below the average for a sports‑car of this age. Such low utilisation can be benign, yet the limited mileage also suggests the vehicle may have spent extended periods stationary, which can accelerate tyre rubber ageing and increase the risk of sidewall cracking even without high mileage. No large mileage spikes appear in the MOT record, so the wear pattern is likely driven more by age and storage conditions than by high‑stress use. When inspecting the rear wheels, verify that both tyres are free of visible ply exposure, sidewall bulges, cuts or cracks, and that the tread depth is even across the width. Spin the wheels to listen for any thudding or wobble that could indicate rim damage or loose wheel nuts, and feel for play in the wheel bearings by checking for excessive axial movement when the wheel is rocked. On a test drive, monitor for vibration or a thump over bumps, and watch for any pull to one side that might reveal mis‑alignment or worn rear suspension bushes, which can exacerbate tyre wear. Given the vehicle’s low mileage but documented rear‑wheel failures, a focused pre‑purchase inspection should include a thorough assessment of the rear axle assembly, wheel bearings, and suspension components such as rear control‑arm bushings and anti‑roll bar links. Confirm that the repaired wheel conforms to OEM specifications and that torque settings on the wheel bolts are correct. Finally, have the current rear tyres examined by a qualified tyre specialist to ensure the rubber compound has not deteriorated with age, as this will be critical to maintaining roadworthiness despite the modest mileage.
