The contact area between the
ground and tire faces the tread
layer completely. Thus the driving
force and the braking force are
optimized, and the tire is worn out
evenly resulting in increased life.The contact area between the
ground and tire is not enough,
so the tire is worn out unevenly
and the tire is vulnerability to
outside influence.The contact area between the
ground and tire is excessive, so
a lot of heat is generated and
the tire is worn out unevenly
and abnormally.
