Absolutely not, Frank? How can you say that? A tabulation of rolling resistance of tires done by a "green" organization showed that the small-diameter tires on 14" rims had lower rolling resistance than the big tires mounted on 16" rims.

If we were talking steel railroad wheels I would agree but we are not.

But if you have data refuting that, I'd love to see it.
