Here is a fun one:
Why do race cars have wider tires?
I came across this one on some forum so I thought I should share, even though most of you already know it :D

the reason is that
the designer know all about friction, there is much consideration about coefficient of friction,
the softer the rubber the better the friction, then the softer rubber needs to be wide enough.
this is the reason.
Read my Profile. :D
Shayaan_Mustafa is right, well you are all right, more or less.
Coefficient of friction doesn't depend on the contact area directly (this is very counter intuitive, at least to me), it depends on the "stiffness" of the rubber. So the softer the rubber the better. But since it is softer it needs larger contact area to support larger tangential forces.
There are other reasons but this one I found very interesting.
Nice Question And Gr8 Explanation...Found It Intresting!! :D
