Due to the tyre rolling resistance.
I can in fact push a van weighing several toinnes on well pumped up
tyres on a dead smooth flat road.
I'm talking about a small ship like say a trawler where I've seen it done.
I'll bet you'll not move a truck weighing anywhere near as much.
You only need to look at how much load a single horse could pull on a canal
barge.
