This is a very interesting discussion.

Concensus of experienced gluers seems to be to glue only the outer edges rather than the whole width of the tyre to the wheel.

I've been thinking abut this for a long time and wondering if glued edges only are good enough. Certainly it will stop the tyre from coming right off and will prevent the wheel from spinning inside the tyre but . . .
it would appear that the centre tread could still lift, thus increasing the tyre diameter at high speed and also reducing the grip because of the now reduced flat area available to remain in contact with the track. This could be considered a GOOD feature in that it will probably only occur on high speed straights where the increased diameter would enable even higher velocity and the decreased grip wouldn't matter at all. On the other hand, it could create vibration through uneven stretching and temporarily losing concentricity (roundness!). Also, under vicious acceleration on both straights and curves, under wheelspin, the loss of effective friction area would be disadvantageous.

Any comments on these points?
Does anyone glue the full width of tyre to the wheels?
