The CSC tutorial for changing the front tire of the TT250 is located at the following link.

Looking at the photographs, the front wheel of the TT250 appears to be the same as the front wheel of my Zongshen ZS200GY-2. If so, the brake rotor is different. Also, the right side of the hub, which connects to the speedometer drive gear, is also different.
