china's stuffs not in the same level with the us/japan's

i recently looked at tires 315/80/22.5

michelin, goodyear, bridgestone, yokohama, sumitomo, bf goodrich, hankook... i could use any one of those brands, price range 600-900 apices.

but chinese ones doublecoin, sailun, tornado, aufine...  were at about 250-400 apiece.  cheap but i won't buy it, as too big of stake if one ever fails in the move.   i know all of people in my group won't get chinese ones no matter how cheap they are as in their eyes "they are junks".   what are those pinkos pride of?
