2021 Citroen C3 Aircross Shine + P-Tech S/S 1.2L Petrol · SC70 BYV

A clear pattern of premature, edge-related tyre wear defines the mechanical history of this Citroen C3 Aircross, with every recorded MOT since 2024 flagging tyres at or near the legal tread limit. The most recent test on 14 April 2026 passed with advisories on both rear tyres being worn to approximately 2.5mm and feathered on the edge, repeating the same edge-wear issue noted on the fronts in 2024. No structural defects, brake failures, suspension failures, or corrosion advisories have been recorded across three consecutive passes, and the only non-tyre advisory was a defective front exhaust mounting noted in January 2025. The recurring advisories point to a consistent geometry or suspension geometry-related concern rather than any single isolated incident, and this trend warrants close physical inspection rather than being dismissed as routine consumable wear. With 29,778 miles accumulated over five years, annual usage works out at approximately 5,956 miles, which is notably below the typical mileage band for a vehicle of this age. The MOT record shows tests at roughly annual intervals from February 2024 through April 2026, with no evidence of long dormant periods or significant mileage jumps between tests, indicating the car has been in steady but light service. Low annual mileage of this nature generally preserves engine and drivetrain longevity but can accelerate sidewall deterioration in tyres, promote corrosion in less-used brake components, and allow rubber bushes and mountings to dry out through underuse. The wear pattern observed here is entirely consistent with that profile. Given the repeated edge-wear advisories on tyres of varying axle positions, a prospective buyer should prioritise a thorough inspection of the suspension and steering geometry before purchase. Specifically, check for play or wear in the front and rear suspension arms, anti-roll bar bushes, and trailing arm bushes, all of which are common culprits for causing the inner or outer shoulder wear recorded on this vehicle. On a test drive, listen for clonking or knocking noises from the suspension over speed humps and uneven surfaces, and pay particular attention to any pulling to one side under braking or straight-line running, which would indicate geometry out of specification or a worn component distorting wheel alignment. The condition of all four tyres should be physically inspected for uneven tread depth across the width, and a four-wheel alignment check should be considered a sensible precaution regardless of how new the replacement tyres may be. The single advisory regarding the front exhaust mounting noted in early 2025 also warrants a hands-on check, as a deteriorated rubber hanger can allow the exhaust to sag, contacting the underbody or heat shield and producing a rattle or drone that worsens on throttle lift-off. With the car now beyond the manufacturer warranty period and approaching five years of age, attention should also be paid to the condition of the underbody mounting points, brake pipes, and suspension subframes for any early signs of surface corrosion, even though none has yet been flagged at test. Finally, confirm the age and condition of the 12V battery, as low-mileage vehicles frequently suffer reduced battery capacity through prolonged standing between short journeys, which can manifest as slow cranking or intermittent electrical glitches rather than a complete no-start.
