2015 Toyota Yaris 1.5L Hybrid electric · SB65 HBO

The 2025-10-27 MOT for this 2015 Toyota Yaris resulted in a pass at 71,404 miles, but a failed MOT just two days earlier revealed significant tyre issues. The nearside and offside front tyres had exposed ply or cords, and both front tyres were below the legal tread depth of 1.6mm. These defects indicate severe tyre degradation, likely due to prolonged under-inflation, uneven wear, or lack of rotation. The failure highlights a critical safety risk, as tyre integrity is vital for control and stopping distance. Recurring mechanical patterns show consistent tyre wear issues dating back to 2022. Tyres were noted as "worn close to legal limit" as early as 2022, with edge wear and reduced tread. Brake discs also show progressive wear: pitted or scored discs were recorded in 2022, 2023, and 2024, with one instance of a "worn, pitted or scored" rear disc in 2024. Suspension arm bush wear was noted in 2024 but not in later tests, suggesting potential repairs or less severe progression. The trend indicates worsening tyre conditions over time, with the 2025 failure representing a more severe deviation from legal standards than earlier reports. Brake disc wear remains consistent but not immediately critical.
