Here are the stock tires for the Zongshen RX3; they appear to be CST C6017 tires, which are not available in North America.

These are probably the tires which will be stocked by CSC Motorcycles. However, these tires are listed by CST as street tires, and the tread is not very aggressive. I'm sure these tires will perform poorly in mud.

The CST C7208 is a much better choice, but is also unavailable in North America. I would hope CSC Motorcycles would import the CST C7208 instead of the stock tires.

However, none of the 15-inch tires are as good as the 17-inch, or 18-inch tires readily available in North America. If I bought a Zongshen RX3, I would certainly convert to either a 17-inch, or 18-inch rear tire.
