When we say tire pressure is so much, that means there is so much

That's true.  The magnitude of the force is given by the pressure and
the area, both scalars, and the direction of the force vector is
normal to the tire wall.

 
Something that I forgot to mention.
 
Although all of the above is true, it talks only about the force on the
wall. There is also pressure all the way through the interior of the tyre.
 
In what direction is that pressure acting? If we accept that pressure is
a scalar, there is nothing more to explain. If it's a vector, then away
from the walls it is acting in all directions, which is at least a
little weird.
