I noticed the same thing when I threw a new set of Conti Road Attack tires on my bike last year. The front clearly shows it was "Made in Korea" and the rear displays "Made in Germany." I thought it was odd and questioned it, however, I was also in dire need of a new set of tires. The originals had already clocked over 11K miles on them. Anyway, my Conti's now have over 4K miles on them and seem to be holding up well. I don't notice any difference between the tire made in Korea or the one made in Germany, other than the lettering on the sidewalls. IMO, they're a huge improvement over the original Michelin Macadams!
