I put a front wheel skirt on one side and It hasn't blown off yet:
Poly tubing ready for baking at 220 for 15 minutes:
Poly tube formed attachment screwed into inner fender:
Wheel skirt mounted on fender:
I used 4 cable ties on top around the poly tube and a bungie cord on both lower corners to pull it in. I can hear it rubbing the tire sometimes. I think a spacer pushing at the wheel center would help.
