I just got in a couple of Shinko 244 dualsport tires for one of my CT90s. Shinko is a Japanese company, but the tires are made in Korea. I was sure they weren't made in Japan, for the $44 I paid for each. Tire technology is really not all that complicated, and no doubt any country that makes tires can make good ones.
