If they looks mint you can trust them. If they have cracks all around the tread you know there old. Lol my couson had a 1985 clan clover with cracked old tyre and the 2 cambelts looked the same.
He used it for 2 weeks before selling it for £2500. I could of had it cheap as he got it for £170 but its been done up on a tight budget.
