Now my mother has got four new tires (Conti Ecocontact CP). So far so good! The test is only that they are different old: 03. KW 2003 12. KW 2004 10. KW 2004 18. KW 2005 What do you say about it? Tomorrow I will go to the dealer, demand the managing director and complain about it. If you have good arguments, then always bring it here! Since we will never go to this factory town again, because they will also go to this factory city visit in other respects than more than incompe I want to tell him the right opinion (of course in an upscale and diplomatic way!). By the way, it is not a Renault dealer, but VW, because my mother drives a passat, but I feel somehow more comfortable in this forum :-).
