To my guess - about a 20% difference in spinning and 50% difference in energy if they were equal mass. About every scientific test I read seems to think bikes ride on a plane. They don't. Dumb tests. Don't believe them.
So when the rider went around the block (say ~.4 miles if each side is about a tenth of a mile) the wheels would have gone around about 300 times. Based on the valve stem location the front wheel may have gone around 300.5 times while the rear wheel went around 300 times - totally insignificant difference.
