Recently purchased an Audi A4 S-line 3.0tdi Quattro Cabriolet. The wheels fitted are the 18 inch s-line five spokes. Condition wise they are ok but they have been refurbed around the outer edge and they are now showing signs of the paint discolouring. I'm going to repaint them myself but I'm trying to locate an aerosol that will provide a near OEM match. Tralwed the net and found that wurth do a supposed match but it would be nice to draw upon the experiences of others. I can paint and the wheels don't need a great deal of attention to get them looking as they should but obviously the paint colour and finish will determine whether they look as they should or shocking!! Also could someone advise whether 245/ 40's would sit ok on the wheels, any experiences of wider tyres and clearances? Wheel offset is ET43.
