I was going to add this into Luoma's topic on tires, but thought it might get lost in the shuffle. I have a set of Chinese tires on my car labelled SEG and they are proving themselves. Only tires I have had that seem never to require air and the tread is holding up okay. Also see that there is, apparently, a Chinese Metzler clone, and the CMW sells another non-Metzler style for about half the price of Dunlops and the others. Anyone have experience with them?
