Old Avon tyres

[Tony Griffiths]

I suppose that it depends on the date code, condition and the risk you want to take. This explains older and newer date codes: https://www.oponeo.co.uk/blog/tyre-s-dat...anufacture. There is no law that mentions the age of a tyre on a private car, only certain classes of commercial vehicles are forbidden from using tyres older than 10 years. Even here there are certain exceptions including "historic" commercial vehicles no longer used commercially and - rather surprisingly - re-treads where the date of re-treading is taken as the manufactured age. Hence, you could legally drive your car on tyres that appear externally to be perfect - but were made in 1920. The snag is, what deterioration has happened inside?
Send yourself to sleep and read: https://www.legislation.gov.uk/uksi/1986...on/27/made and https://www.legislation.gov.uk/uksi/2020...ion/2/made etc.
