[QUOTE=holypaulie;103808] Question? Should I cover open part of tire?
Answering the question in #3 of your original post in this thread. Cover only the top half of what appears of the tyre in your photo. Make it deflect air smoothly around. The bottom of the tyre where it is in contact with the road is quite stationary. So from the bottom, the contact point, to halfway up your photo, the forward speed of the tyre is quite low.
