Hi, I have a new model C5 VTR estate 2.0 hdi. Does any body else have abnormal tyre wear. Since new 7500 miles I have experienced abnormal tyre wear, the original front tyres are nearly 75% worn out after 6800 miles. I have had the steering geometry checked twice by Citroen, who cannot find anything wrong. After the last geometry check I had the rear tyres which looked like new put on the front (450 miles ago). Since then the tyre tread on the out side looks as if it has cuts in it and looks like the tread has experienced an amout of chattering. Tyre pressures are checked once a week, driving conditions are normal. After motorway driving the tyres look normal, however if I have a period of round town driving the chattering and cuts soon come back. I should add that the steering feels completely normal. I would appreciate any feedback.
