Tyres and roadwheels

Test Description

Tyre condition

The reason for failure with respect to tyre wear is:

"The grooves of the tread pattern are not at least 1.6mm throughout a continuous band comprising: the central three-quarters of the breadth of tread around the entire outer circumference of the tyre".

Tyres must be correctly matched with regard to:

• type
• size
• structure
  
  NB. type or structure but not both.
  
• tyres on the same axle must be of the same structure and size.

Also examined:

• general condition of tyre
• condition of valve.

  Tyres fail if they have serious cuts, bulges or other damage.

  The wear on the tyre is checked with a tyre tread depth gauge to ensure compliance.

  The tyres are examined to ensure that there is no fouling with any part of the vehicle.

  Notes: Although under-inflation is not in itself a reason for failure, a brake test may be inadvisable because of possible damage, and it may affect headlamp alignment. The condition of the spare tyre is not part of the MOT.

Wheel condition

• damage
• distortion
• cracks
• distorted bead rim
• securely attached to the vehicle
• no wheel nuts or studs missing.

  An externally fitted spare wheel or spare wheel carrier must not be so insecure that it is likely to fall off.
