think of it in terms of surface area. The weight of the car is spread out over that surface area.

The more tire touches the ground, the more the car's weight is spread evenly.

Call it the difference between for example, what if the car's tires were NAILS?! they'd poke through the ground. Even if the tips were flat. The car's weight is spread over the 4 tips of those nails.

put 4 cement blocks on instead and the weight of the car is spread over the surface area that those blocks have on the ground. Those pounds are spread over a great square inch surface.


I hope it maeks sense, because if it does then that's the principle behind why a narrow tire cuts through snow instead of being above it.


if u want another example... the difference between standing on one water ski and letting ur body sink and standing on a wake board and letting ur body sink.

To cut through the water, the wakeboard has to displace THAT much more water to make room for it to go through. The amount of water that has to be 'shoved' out of the way dictates how much resistance there is.

the ski has to move MUCH less water to get through it. Hence, less water being displaced means less resistance.



... that's about as best as I can explain it in english AND over the internet.
