How old is the tyre on your spare wheel?

We were recently called by a new customer as he had two flat tyres on his Ford Fiesta leaving the vehicle unusable.A couple of days ago our customer had a puncture in a rear tyre so he fitted the spare wheel to the vehicle and continued with his journey.The next morning he noticed that the spare tyre was completely flat so he was not able to use the vehicle to get to work.On arrival and after inspecting both tyres we informed him that the spare tyre was actually eleven years old and as soon as it was put on the vehicle it went flat as the strength of the tyre had weakened over the years.We left the customer with two new tyres fitted to the rear axle and importantly a usable spare.We recommend that all motorists check the age and general condition of the spare tyre so it can be used effectively in the event of an emergency.
