For example:
TREAD wear 200
TRACTION AA
Traction - AA, A, B & C
The traction  grades, from highest  to
lowest,  are AA,  A, B  and  C. Those
grades represent  the  tire’s ability  to
stop  on   wet   pavement  measured
under controlled conditions on  spec-
ified   government  test   surfaces  of
asphalt and  concrete. A tire  marked
C  may  have poor  traction  perform-
ance.
Tread wear
5.
Maximum permissible inflation
pressure
The tread wear  grade is a compara-
tive rating based on  the wear rate of
the tire when tested under controlled
conditions  on   a  specified   govern-
ment test course. For example, a tire
graded  150 would  wear  one-and-a-
half times  (1½)  as well  on the  gov-
ernment course as a tire graded 100.
The  relative   performance   of  tires
depends upon  the actual  conditions
of   their   use,   however,  and   may
depart  significantly   from  the  norm
due  to  variations  in  driving  habits,
service  practices and  differences in
road characteristics and climate.
This number  is the greatest  amount
of air pressure  that should be  put in
the tire. Do not exceed the maximum
permissible inflation  pressure. Refer
to the  Tire and  Loading Information
label   for    recommended    inflation
pressure.
WARNING
The traction  grade assigned  to
this  tire  is  based  on  straight-
ahead   braking  traction   tests,
and does  not include  accelera-
tion,  cornering,   hydroplaning,
or peak traction characteristics.
6.
Maximum load rating
This number indicates the  maximum
load  in  kilograms  and  pounds  that
can  be   carried  by  the   tire.  When
replacing  the  tires   on  the  vehicle,
always use  a tire that  has the same
load  rating  as  the  factory  installed
tire.
