...turbo diesel? ? I have done about 4000 miles since having two new rear tyres approx 5 months ago. I have now been told during a service that they need replacing. They were top of range tyres, Bridgestones I think. I have been told that they are feathering but I don't know what this means. Am going to garage to discuss further later but am obviously concerned and would like to know a bit more before I confront them.
