Well on bicycles anyway, larger diameter wheels reduce rolling friction, so that could be inferred to car tires also. Probably something to do with the weight spread over a longer patch and less or more gradual flex of the tire.

All else being equal...hmmm.

The disadvantage is that more weight is farther from the axle meaning more energy used to spin them up and slow them down and turn them.
