The other explanation makes more sense but I get what you are trying to say.
The fact here is that a heavier object does take more energy to get moving but once moving has more momentum. Yes, lighter wheels/tires are still better like you said, because of the unsprung mass, but once moving shouldn't take more energy than a lighter wheel. Obviously there are so many factors that in to this, mass, friction of tires and air, speed, etc.yes, on
Yes, on a flat road or going downhill something heavier may have more momentum than something equally shaped and sized just lighter, but try to push that 50lb ball uphill, even when it’s already moving, and you will certainly find it easier to push a 20lb ball uphill that’s moving much easier.The other explanation makes more sense but I get what you are trying to say.
