What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with less than 1.0 mm thick - it accounts for 34.7% of failed tests on this model.
- Then check tread depth is below minimum requirements of 1.0mm and remains on when the brakes are released, the next two most common reasons.
- The most common advisory is less than 1.0 mm thick (9% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 24,808 miles, which is the number to compare any advert against.
