Newton`s 2nd Law
... More interesting still, friction does not depend on the area of contact. Slide the crate on its smallest surface and all you do is concentrate the same weight on a smaller area with the result that the friction is the same. So those extra-wide tires you see on some cars provide no more friction than ...
