I have been debating for a long time if lightweight 22” rims will be as big a penalty in efficiency as the Tesla turbines. And wider tires vs 245’s
There is a lot of information on this forum stating up to 20% hit.
I came across this article performed by velonews looking at the energy efficiency of bicycle tires. Different widths and inflation pressures.
Their conclusion if I read properly is that a light weight I sprung mass with a low profile wide tire will have the lowest rolling resistance.
Also I came across another article that basically stated that above 40 mph the aerodynamic drag eclipses the rolling resistance, so it might only be a hit if most of your driving is below 40 mph.
