Hi Have just purchased a C5 1.6hdi 57 plate estate with the top spec alloy wheels. I have just had them properly balanced at £30 cost all the tyres have some life left in them the only down side is one does have a slow puncture so I have to top it up every couple of weeks. I will do a straight swap for some 15" steels with hub caps (not too worried about scuffs etc.) as I do high mileage and want the the steels as they are more efficient. I live near Brighton and work in Reigate for anyone interested. Many thanks H
