Hello, unfortunately it caught me and I drove with a nail into the tires, fortunately very clean in the middle of the tread. So I drove briefly to the friendly dealer and he wanted to look. 10 minutes (!!!) later he came back to me and said it would be repaired. I think, yes great and driving cheerfully from Hof. Somehow I found the repair right quickly and Googled once. There are different procedures of repair. So I heu Is it possible that a Kia Optima GT, V-Max according to the papers 235 km/h, the tyre is one with the identification Y, up to 300 km/h. Is such a reliable thing? Had read that such a thing was only an emergency solution and that the tyre had to be replaced immediately…?!?
