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 28.6% of failed tests on this model.
- Then check tread depth is below minimum requirements of 1.0mm and indicates excessive fluctuation of brake effort, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (8.7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 23,942 miles, which is the number to compare any advert against.
Pass rate by age
A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 6-10 years | 80.36% | 387 | |
| 11-15 years | 86.42% | 81 |

Most common advisories
Not a failure and not a legal requirement to fix - but an advisory that repeats year after year is money the next owner spends.

| 2 | Indicates excessive fluctuation of brake effort | 7.4% | 35 | |
| 3 | Has a serious fluid leak | 4.7% | 22 | |
| 4 | Less than 1.0 mm thick | 4.7% | 22 | |
| 5 | Significantly and obviously worn | 4.7% | 22 | |
| 6 | Excessively stiff or notchy | 4% | 19 | |
| 7 | In such a condition that it is seriously weakened | 3.8% | 18 | |
| 8 | Corroded so that its cross sectional area is reduced and seriously weakened | 3% | 14 | |
| 9 | Tread not clearly visible | 3% | 14 | |
