2015 Smart (mcc) Forfour 0.9L Petrol · W13 SBS

The most recent MOT, carried out on 3 July 2026, was passed but returned several tyre‑related advisories: both rear tyres were noted as worn close to the legal limit and showing edge wear, and the TPMS warning light remained illuminated. Over the previous three years the pattern has been a steady increase in tyre‑wear advisories, moving from front‑tyre edge wear in 2024 to rear‑tyre edge wear in the latest test, while no structural or safety‑critical defects have been recorded. This suggests the vehicle’s overall mechanical condition remains sound, but the tyre condition is deteriorating and requires attention. At 55,396 mi the 2015 Smart Forfour averages just over 5,000 mi per year, which is well below the typical UK usage of around 10,000 mi annually. The low mileage indicates the car has likely spent considerable periods idle, which can be as consequential as high mileage for certain components. Prolonged standing can accelerate rubber hardening, battery sulphation, and corrosion of brake discs and suspension joints, even though the recorded mileage places little cumulative wear on the drivetrain or engine. Prospective buyers should give the tyre set a thorough visual and tactile inspection. Look for cracking, sidewall perishing, and uneven tread depth, especially on the inner edges where the advisories have repeatedly flagged wear. Verify that the TPMS sensors are functional and that the warning light can be cleared after a reset; a persistent TPMS fault may indicate a sensor battery failure or a wiring issue. During a test drive, listen for any thumping or vibration that could signal mis‑alignment or worn suspension bushes, and feel for any pull to one side which would corroborate the edge‑wear pattern. If the tyres are approaching the legal minimum tread depth (1.6 mm) or exhibit significant cupping, replacement will be imminent and should be budgeted for. Given the vehicle’s age and low‑use profile, also examine the 12‑volt battery for voltage drop and signs of sulphation, and consider a load test to confirm remaining capacity. Inspect the brake discs for surface rust or glazing, especially if the car has been parked for long stretches, and ensure the calipers move freely without binding. Check all fluid levels – engine oil, coolant, brake fluid and power‑steering – and note the dates of the last service; fluids degrade over time even without mileage, so a comprehensive change may be prudent. Finally, look for corrosion on the chassis, wheel arches and exhaust system, and confirm that any service book stamps align with the recorded MOT dates, as consistent servicing will support the car’s continued roadworthiness.
