MASERATI GRANTURISMO2015 · 4.7L PETROL

The most recent MOT on 2025-07-24 recorded multiple tyre-related issues, including all four tyres worn close to the legal limit and showing edge wear. The nearside rear tyre had a nail, and the TPMS light remained on. This followed a failed MOT just three days earlier (2025-07-21), which listed identical tyre wear defects, plus an offside front tyre with exposed ply or cords—a more severe condition. Both incidents highlight recurring tyre degradation, likely linked to uneven wear or insufficient tread depth. The pattern suggests a persistent risk of tyre failure, exacerbated by the vehicle’s low mileage (3,767 miles annually). While low mileage often implies lighter use, it can also lead to uneven tyre wear if the car is parked for extended periods or driven short distances. The absence of defects in earlier MOTs (2024-2022) indicates this issue emerged recently, possibly due to changing driving habits, storage conditions, or undiagnosed alignment/suspension problems. The trend shows a worsening condition: the failed MOT included a critical defect (exposed ply), while the subsequent pass only noted the same wear without addressing the underlying cause. This raises concerns about whether repairs were thorough or if the tyres were merely replaced without resolving root issues. The TPMS light persisting across both tests also points to an unresolved system fault.
