2018 Ford Fiesta 1.0L Petrol · SN18 VXK

Tyre tread condition dominates the mechanical picture of this 2018 Fiesta; the latest MOT on 8 September 2026 recorded the front tyre as worn close to the legal limit and, three years earlier, both rear tyres were flagged for the same degree of edge wear. Apart from a single exhaust‑lambda failure in August 2021, every other test since 2021 has been passed without recorded defects, indicating a generally clean roadworthiness record but a recurring need to address tyre wear before it becomes a safety issue. At 67 534 mi the vehicle averages roughly 8 400 mi per year, a mileage rate that sits comfortably within normal usage for a car of this age. The MOTs have been carried out at roughly annual intervals, showing no prolonged periods of inactivity that might suggest hidden corrosion or component seizing. This moderate annual accumulation suggests that wear on consumables such as tyres, brakes and suspension components will be progressing at a typical pace, but the approaching tread limits mean the next tyre replacement is imminent. When inspecting the car, give particular attention to the condition of all four tyres: probe the tread depth across the centre and edges, feel for any soft spots or bulges, and listen for road‑noise that may indicate uneven wear or internal damage. During a test drive, monitor for any vibration or pulling to one side, especially when cornering, which could reveal underlying alignment or suspension issues that often accompany uneven tyre wear. Although no suspension or brake advisories appear in the MOT history, it remains prudent to check for loose or worn suspension bushes, any knocking over bumps, and consistent pedal feel, as these components can deteriorate silently. Finally, verify that the exhaust system and lambda sensor are operating correctly; the 2021 failure suggests the sensor once fell outside its specified range, which can manifest as a rough idle, reduced fuel efficiency or a persistent check‑engine warning. A quick visual inspection for exhaust leaks, rattles or soot, followed by a short drive to confirm stable idle and smooth acceleration, will help confirm that the emissions system has been rectified and is now reliable.
