Where should I put the seam when I attach tread to the IFI-Wheels?
Each wheel has a symetrical pattern of rivet holes on the RIM pieces. For optimal load distibution among the rivets, place the seam in the center of one of these patterns. Then insert the rivets in the holes closest to the edge (balanced on either side of the seam). Insert additional rivet holes as necessary.
Do I need to use adhesive to attach the tread to the IFI-Wheels?
**No. The wheels are designed such that one may use aluminum rivets to attach the tread, with NO adhesives. This is a method used successfully by many FIRST teams.
The use of adhesive will make it more difficult to change wheel tread, but will more securely attach the tread. Is this extra strength of attachment needed? Probably not.
Each team should test their wheels before competition to ensure their method of tread attachment meets their needs.**
