I just had my tires changed, after 9 years due to the fact that I am not driving much these days. The tires were starting to show cracks on the sides but also on the part in contact with the road. Just for information, many stores will refuse to change your tires if they are 10 years old or more for safety reasons.Anyway, I checked the new tires afterwards and noticed that the caps were not of the same style and shape. Weird but I guess the garage just applied whatever was immediately available
