This British Standard specifies requirements for the retreading of car and commercial vehicle pneumatic tyres for road vehicles primarily designed for use on the public highway and first used after 3 January 1933. It specifies inspection procedures for the tyre carcass before and during processing, repairing and processing details, rubber depth under the tread pattern, tread pattern information, and rotating drum verification tests. The requirements apply to both tubed and tubeless retreaded tyres.

The standard does not apply to:

  1. tyres designed for use on pre-1933 vehicles, as their design and construction may be unique and outside the range of tyres in current use;
  2. temporary use spare tyres; or
  3. tyres with speed categories VR or ZR.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
