2019 Citroen C3 Aircross 1.2L Petrol · CF19 AXU

A clear pattern of tyre wear across all four wheels, flagged repeatedly over consecutive MOT tests, defines the mechanical story of this 2019 Citroen C3 Aircross. The most recent test on 18 September 2025 recorded a pass but issued an advisory for a worn, pitted, and scored rear brake disc, which sits on top of a 2024 test where every tyre on the vehicle was noted as worn close to the legal limit, particularly on the outer edges. Earlier tests in 2023 and 2022 followed the same trajectory, with nearside front tyre edge wear appearing in 2023 and no recorded defects in 2022. The overall trend points to a chassis that has been consuming its consumables faster than the annual mileage would ordinarily suggest, with the brake disc advisory in 2025 indicating that braking components are now beginning to follow the same accelerated wear path. Recorded mileage of 31,082 miles over seven years equates to roughly 4,440 miles per year, which is low for the vehicle's age and type. There are no gaps between the annual test entries, so the car appears to have remained in regular use without prolonged standing periods. Mechanically, low annual mileage of this nature typically reduces wear on the drivetrain, clutch, and internal engine components, but it can also bring forward issues with under-used items such as brake discs corroding or pitting on the friction surface, exactly as recorded in the 2025 advisory. The discrepancy between low mileage and the recurring edge-wear advisories on the tyres suggests a suspension or alignment factor rather than simple mileage-driven wear, and this warrants close inspection. For a prospective buyer, the priority checks should centre on the suspension geometry and wheel alignment, given that four tyres have been flagged for edge wear in succession. On a test drive, listen for clonking or knocking from the front suspension over speed humps and uneven surfaces, particularly from the wishbones, anti-roll bar links, and top mounts, and feel for any pulling to one side under braking or steady motorway cruising, which would suggest tracking misalignment or a worn bush allowing geometry change under load. Inspect all four tyres for uneven shoulder wear and check whether the tracking has been corrected, as uncorrected misalignment will continue to consume tyres regardless of replacement. Pay particular attention to the rear brake discs on a visual inspection, looking for a pronounced lip on the outer edge, visible pitting or rust patches across the friction surface, and any judder felt through the brake pedal under firm application, as the 2025 advisory notes the disc is already pitted or scored and may now be approaching the point where replacement is necessary. Given the consistent pattern of tyre-related advisories over four consecutive test entries, a pre-sale inspection by a specialist familiar with the C3 Aircross platform is advisable, with particular focus on the rear suspension bushes, trailing arms, and any worn subframe mounting points that could be allowing toe misalignment at the rear axle. On the test drive, check for any vibration through the steering wheel at speed, which combined with the brake disc advisory could indicate a disc that is now within tolerance but at risk of warping. Confirm the date stamps and condition of the currently fitted tyres, as the vehicle may have been turned out with fresh rubber to mask the underlying alignment or suspension issue. Finally, request evidence of any recent geometry work and inspect the rear brake discs directly for wear depth, as addressing the suspension root cause will be more cost-effective than repeatedly replacing tyres.
