All:

I'm thinking ahead to my next set of tires for the Jialing JH600, which comes stock with Chengxin road tires in sizes 100/90-19 and 130/80-17. I've had a squiz through Taobao but not come up with anything.

Any bright ideas on how/where to find quality tires, and suggestions for what might be a "toothier" tire for non-paved riding -- albeit one that's available somewhere in China?

thanks!
