I'd be interested in people's personal measurements of differences. If someone here had access to some long, gentle downhill and kept track of terminal coasting speed using different tires, different tubes, but otherwise identical equipment, terminal coasting speeds might be good information.
It would be best to test in consistent temperatures and with negligible wind, of course.
