2015 Mercedes-Benz CLS 2.1L Diesel · D9 RJP

The most recent MOT test on 21 May 2026 resulted in a pass at 68,225 miles, but the history reveals a specific and recurring issue with the front tyres. The tester recorded an advisory for the offside front inner tyre being worn close to the legal limit or on the edge. This is a critical detail because it suggests the vehicle may be suffering from poor wheel alignment or suspension geometry. The mechanical trend shows a pattern of accelerated tyre wear rather than general neglect. In June 2024, the car failed its MOT specifically because both front tyres had exposed ply or cords, which is a dangerous defect. At that same time, the front brake pads were also noted as wearing thin. While the brakes were likely addressed to pass the retest five days later, the return of a tyre wear advisory in 2026 indicates the underlying cause of the 2024 failure may not have been fully resolved. The mileage context is roughly typical for the vehicle's age, averaging about 8,500 miles per year. However, the condition of the tyres relative to this mileage is concerning. The car has covered only around 5,500 miles since the clean MOT in June 2025, yet a front tyre is already worn close to the limit.
