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 36% of failed tests on this model.
- Then check remains on when the brakes are released and not working, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (6.3% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 34,605 miles, which is the number to compare any advert against.
