I have checked my wife's Fiesta’s wheels. They are 17" diameter and the tyres are 195/45 R17 Eagle FI. Why would a local Ford dealer fit 17" wheels? Not asked for by us? Why when I asked them was I told that there were no other wheels that would be stronger other than steel wheels used for ‘off roading’? They never mentioned 15" wheels as being available! I am getting very suspicious about the advice I have been given. Why would this garage tell me that they were changing four sets of wheels a week due the road conditions in Gloucestershire? Surely Ford Motor Company would not allow their cars and wheels to be substandard like this? Your opinion would be greatly appreciated.
