Hi, How did you manage to get your tyres and wheels replaced under warranty? Was you suffering from the rapid tyre wear on the N/S/F or did you have another problem? I have just noticed that my 2004 C8 'Exclusive' has 15" wheels and tyres fitted when it should have 16" according to the sales specifications. I'm off to my local Citroen dealer to find out why this is and to let them have a go at sorting out my unusual tyre wear on the front. :)
