Perhaps it's because I'm unreasonably dense, but isn't the Force the thing that directly affects coasting?

Are you saying that we can never assume that the load is the same from tire to tire, even on the same car and if we set the same pressures?

I think, that if I am looking for tires to put on one specific car (e.g., my own car) that if I am allowed to set whatever tire pressure I want, the load would be the same no matter what the specific tire was. So in that case, the tire with the lowest measured force resisting movement would be the best one for efficiency.

Can you please show me where I am getting this wrong?
