A highly streamlined object drafting another highly streamlined object will actually cause drag to increase for both. Drafting only works when large areas of separation exist (i.e. blunt bodies). Well faired bicycle tires are probably approaching airfoil drag values.

I would suspect the reason for using one large wheel is lower weight (less suspension components), lower rolling resistance, and its use as a flywheel to smooth out pulses from the rider.
