The law requires part-worn tyres to be labelled and to meet minimum safety standards
This guidance is for England, Scotland & Wales
The Motor Vehicle Tyres (Safety) Regulations 1994 set out minimum safety standards for the supply of part-worn tyres. To comply, it is important that you and your staff are fully aware of these Regulations.
Under the Regulations, it is illegal to supply any part-worn tyre that is capable of being fitted to a motor vehicle or trailer unless certain conditions are met regarding specific markings and the general condition of the tyre.
Most importantly, all types of part-worn tyre must be marked 'PART WORN', any repairs to tyres must comply with British Standards and it is illegal to have unsafe tyres in your possession for sale.
Part-worn tyres (except retreads) should have an ECE approval mark (for example, E11) and a speed and load capacity index (for example, 76 S) moulded into the sidewall at the time of manufacture.
In addition, all types of part-worn tyres must be marked 'PART-WORN' in upper case letters at least 4mm high.
This wording must be permanently and legibly applied to the tyre, otherwise than by hot-branding or cutting into the tyre, and adjacent to every approval mark.
Rubber labels can be cold vulcanised to the tyre and are available from companies that advertise in the trade press.
Part-worn tyres, whether deflated or inflated to the highest operating pressure at which they are designed to operate, must not have:
In addition, the grooves of the original tread pattern of the tyre must be at least 2mm deep across the full breadth of the tread and around the entire outer circumference of the tyre.
Part-worn retreaded tyres
Part-worn tyres that have been retreaded must have one of the following:
The indication 'PART WORN' must also appear next to the BS or ECE approval mark, or next to the word 'RETREAD'.
For tyres marked BS AU 144e, a speed category symbol and load capacity marking should be present.
A tyre has to comply with all these requirements whether or not it is fitted to a rim.
We recommend that a thorough inspection of the tyre be made before fitting to the rim, and also after fitting and inflating the tyre to the highest operating pressure. Tyres that are sold unfitted will need to be inspected with particular care as it is an offence to supply tyres with the defects listed above, even if they only become detectable when the tyre is inflated. Inflation and inspection is recommended.
If a tyre has been repaired, it must have been properly repaired.
Any tyre that has been repaired should be inspected very carefully. Repairs must comply with British Standard BS AU 159f: Specification for repairs to tyres for motor vehicles used on the public highway.
Tyres in storage
It is also illegal to have unsafe tyres in your possession for sale, so you will need to be clear what is and what is not for sale. If you have tyres in storage, but not intended for sale, they should be clearly marked as such.
Failing to comply with the Motor Vehicle Tyres (Safety) Regulations 1994 is an offence. The maximum penalty is a fine and six months' imprisonment.
