There was a time when I refused to buy China tires from, for example, Kumho, Nankang, Sailun or Ling Long. Refused. Or no, I tested on a couple of cars I owned 14-15 years ago and was terribly disappointed with how they performed, but today the situation has really changed. Not because I feel in any way that Michelin or Bridgestone, for example, are no longer worth the money, because they are, but because the Chinese have caught up here too. Almost completely, anyway.
I recently bought Sailun's R888 equivalents Atrezzo R01 and put on my Focus RS and it should be said, those tires grip like a R888 , straight off. For half price. They bite the asphalt so hard that it almost feels bizarre and considering how quickly pure street slicks wear out, it is also not the case that they seem to wear "faster" than for example R888 or Trofeo-R (have previously ridden on both, plus Cup Sport R). In terms of appearance, they are also just right without a rim protection edge, a simple, sparse R tire pattern and a "bulging" tire sidewall, like a slick tire. Very good buy, in other words as they hardly cost anything. There will be China tires in the future as well, for yours truly.
