A recent problem with a 2003 Renault Clio. I left the house, drove 100 yards, heard a big bang from one of the tyres. I fitted the spare, drove 2 miles, heard a second big bang and found that the replacement tyre was also punctured. I called out a local garage who advises a problem with a spring. I seem to recall an item in your column relating to a similar problem. Could you advise please?
