[QUOTE 5172355, member: 9609"]how old are the alloy rims the tyre is on?[/QUOTE]
As far as I’m aware, they were new when the car was new (we bought it secondhand) in 2008.
The mechanic at my local garage told me that the tyre is fine. The alloy rim is damaged (result of a pothole) so he sent me to another garage in the next town which can repair it. So I made the trip and they said they can repair it for £48 inc. VAT. They’ve put a loaner wheel on while they fix it and I should be able to pick it up in a couple of days where they’ll swap the wheels back over.
