Right. Add a bone on the front wheel's axle and call it Tire01. Link the front wheel to it. Add a bone on the rear wheel's axle and call it Tire02. link the rear wheel to it. In your recon bike entry in generals add these at the end of the model module inside the END tag:
FrontTireBone = Tire01
RearTireBone = Tire02
If this doesn't work you'll have to add 2 bone to each wheel, with Tire01 and Tire02 on the front and Tir03 and Tire04 an the back. Then add these lines to Your recon bike instead of the last two:
LeftFrontTireBone = Tire01
RightFrontTireBone = Tire02
LeftRearTireBone = Tire03
RightRearTireBone = Tire04
Hopefully this will work and won't look too bad.
