Hello, I found out today (late, but still), that with my current winter tyre set (205/55 R16 91H) three tyres come from Slovakia and one from Romania. I came up with this because I look at the things more closely as usual when changing tyres, and I noticed that three still have 6.5-7mm profile, one only 5mm. All four were bought at the same time in November 2013 at the dealer. The set has about 30,000km down. The with the 5mm is the Romanian tire. Fr age: Is the problem with the different tires at Conti or with my tyre dealer? I conclude from this that Conti has a problem with the quality of its Eastern European plants. Did Conti write that they should take a stand on the problem. What does your tyre experts think about it? Achja: Auto is a purely long-haul Audi A6 from 2003, 180hp diesel front scratcher.
