Train wheels on steel have zero relevance to pneumatic tires on roads. Their compliance or non compliance has nothing to do with rolling resistance of steel on steel. You could easily make a compliant steel wheel but the compliance will have no impact at all on the rolling resistance.
Pneumatic tire compliance has a direct impact on all aspects of a tire's performance on different surfaces. Off-road tire's are large with low inflation pressures. Tire's for cars racing on very smooth surfaces are at the other extreme. Consumer vehicles are in between. They all need different compliance to fit intended use.
Rather than just making stuff up, a few minutes of reading about tires would save you from appearing ignorant. Read about pneumatic tires, not solid steel ones.
