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 33.3% of failed tests on this model.
- Then check not working and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is less than 1.0 mm thick (7.9% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 45,039 miles, which is the number to compare any advert against.

|---|---|---|---|
| 3-5 years | 80.87% | 6,784 | |
| 6-10 years | 80.59% | 1,978 |
