2015 Mercedes-Benz C 4.0L Petrol · KG11 DLG

A recurring rear‑tyre wear advisory dominates this car’s MOT record, with both nearside and offside rear tyres flagged for edge‑wear and early cracking in 2024 and again for approaching the legal limit in 2025; the latest test on 7 May 2026 passed without defects, indicating the tyre issue has not yet escalated to a failure but remains the sole repeat concern across eight examinations. At 33,927 mi the vehicle averages just over 3,000 mi per year, markedly below the typical usage for a 2015 model. Such low annual mileage can stem from light daily use or extended periods of inactivity, both of which place different stresses on components: consumables such as brake pads and clutch discs will have experienced relatively little wear, while rubber parts and seals may have aged without the benefit of regular motion, potentially leading to hardening or cracking that is not evident in MOT data. When inspecting the rear tyres, verify tread depth exceeds 1.6 mm uniformly across the width and check both sidewalls for any cracking, bulging, or perishing that the advisories hinted at. Uneven wear patterns may point to mis‑alignment, worn rear suspension bushes, or deteriorated rear trailing arms; a test‑drive over a speed bump should reveal any knocks or looseness in the rear suspension, and a brief straight‑line run can expose a pull to one side that would corroborate alignment issues. Beyond the tyre focus, a comprehensive pre‑purchase check should include a visual inspection of brake discs and pads for glazing or uneven wear, a functional assessment of the steering feel for any binding, and a look for any signs of rust on the chassis or subframe that could have developed during low‑use periods. Confirm that all fluid levels are topped up and free of contamination, and listen for any abnormal noises from the drivetrain while the engine is idling and under light acceleration, as these are the most likely areas where hidden wear could surface despite the clean MOT history.
