How to Check 
Use a good quality  pocket-type  gage to check tire 
pressure.  You can’t tell  if your tires are properly inflated 
simply  by looking at  them. Radial tires  may  look 
properly inflated  even when  they’re  underinflated. 
Be  sure  to put  the valve  caps back on 
the valve 
stems.  They help prevent  leaks by keeping  out dirt 
and  moisture. 
Tire  Inspection  and  Rotation 
Tires should  be rotated every 6,000 to 8,000 miles 
(10 000 to 13 000 km). Any time you notice unusual 
wear,  rotate  your tires  as soon  as  possible  and check 
wheel  alignment.  Also check  for  damaged tires  or 
wheels.  See “When  It’s  Time  for New  Tires”  and 
“Wheel Replacement” later in  this  section for more 
information.  If your vehicle  has dual  rear wheels, 
also  see  “Dual  Tire Operation”  later 
in this section.  The  purpose 
of regular  rotation is  to achieve  more 
uniform  wear for all tires 
on the vehicle.  The first 
rotation  is  the most important.  See  “Scheduled 
Maintenance  Services” in the  Index  for scheduled 
rotation intervals. 
If 
your vehicle has single rear wheels, always  use one  of 
the  correct rotation patterns  shown 
here when rotating 
your  tires.

Traction -- A, B, C 
The traction  grades, from  highest to lowest,  are A, B, 
and C, and they  represent the tire’s  ability to stop on 
wet  pavement  as measured  under  controlled  conditions 
on  specified  government  test surfaces 
of asphalt  and 
concrete. 
A tire  marked C may  have  poor  traction 
performance. 
Warning: 
The traction  grade assigned to this  tire  is 
based 
on braking  (straight  ahead)  traction  tests  and 
does  not  include  cornering (turning)  traction. 
Temperature -- A, B, C 
The temperature  grades are A (the highest), B, and C, 
representing  the  tire’s  resistance to the  generation of 
heat  and  its ability to dissipate  heat  when  tested  under 
controlled conditions on a  specified  indoor  laboratory 
test  wheel.  Sustained  high  temperature can cause  the 
material  of  the  tire  to degenerate and  reduce  tire  life, 
and  excessive  temperature  can lead  to sudden  tire 
failure.  The grade 
C corresponds  to a level of 
performance  which all passenger  car tires  must  meet  under  the  Federal  Motor  Vehicle  Safety  Standard 
No. 109. Grades B and A represent  higher 
levels of 
performance  on the laboratory  test  wheel  than  the 
minimum  required  by  law. 
Warning:  The temperature  grade for this tire 
is 
established  for a tire  that  is  properly  inflated  and 
not  overloaded.  Excessive  speed, underinflation,  or 
excessive  loading,  either  separately  or 
in combination, 
can cause  heat  buildup  and  possible  tire  failure. 
Wheel  Alignment  and  Tire  Balance 
The wheels on your  vehicle  were  aligned  and  balanced 
carefully  at 
the factory  to give you the  longest  tire  life 
and  best  overall  performance. 
Scheduled  wheel  alignment  and  wheel  balancing  are 
not  needed.  However,  if 
you notice  unusual  tire  wear 
or  your  vehicle  pulling 
one way  or the  other,  the 
alignment  may  need  to be  reset.  If  you  notice  your 
vehicle  vibrating  when  driving on a smooth  road, 
your  wheels  may  need  to be  rebalanced.
