These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.
Tyre wear
VehicleScore MOT data includes 347 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.
These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.
What to inspect
Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Example MOT wording: NEARSIDE REAR TYRE SLIGHTLY DAMAGED/CRACKING OR PERISHING (5.2.3 (D) (II))
