Hi Fred,

It's going to be tough finding the sizes you want from the few shops that do import brand name stuff. Right now, the Shanghai World Expo and the Guangzhou Asian games have made it difficult for businesses to get stuff through customs. None of my usual sources in Guangzhou have much of anything in stock.

When the supply chain is flowing normally here, there are quite a few people carrying Bridgestone. Ask one of the "importers" in Shanghai, maybe they can special order the sizes you need. When all else fails, I usually stick with Kenda, as they have fairly decent tires that are produced locally.

Cheers!
