P215/65R15  95H  is  an  example  of  a  tire  size  and  load  index  rati ng.
Here is an explanation of the various components of that tire s ize and
load index rating. Note that the tire size and load index ratin g may be
different from the example.
● P
Indicates  a  tire  that  may  be  installed  on  cars,  SUVs,  minivans  and
light trucks as desig nated by the Tire and R im Association (T&RA).
If your tire size does not begin with a letter this may mean it  is desig-
nated by either ETRTO (European Tire and Rim Technical Organiza -
tion) or JATMA (Japan Tire Manufacturing Association).
● 215
“215”  is  the  nominal  width  of  th e  tire  in  millimeters. This  three-digit
number gives the width in millimet ers of the tire from sidewall edge
to  sidewall  edge.  In  general,  the  larger  the  number,  the  wider  the
tire.
● 65
“65”  is  the  aspect  ratio.  This  two-digit  number  indicates  the  t ire’s
ratio of height to width.
● R
“R” is the tire construction sym bol. R indicates “Radial ply construc-
tion”.
● 15
“15” is the wheel rim  diameter in inches.
● 95
“95” is the Load Index. This two-or three-digit number indicate s how
much weight each tire can support.
● H
“H”  is  the  speed  rating.  The  speed  rating  denotes  the  maximum
speed for which the use of the tire is rated.

■Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
■Maximum Permissible Inflation Pressure
This number is the greatest amoun t of air pressure that should ever
be put in the tire under  normal driving conditions.
■Tread Wear, Traction and Temperature Grades
●Tread wear: The tread wear grade is a comparative rating based
on  the  wear  rate  of  the  tire  when  tested  under  controlled  condi -
tions on a specified government  test course. For example, a tire
graded 150 would wear one and one-half (1 1/2) times as well on
the government course as a tire graded 100.
● Traction:  The  traction  grades,  from  highest  to  lowest  are AA, A ,
B,  and  C.  The  grades  represent  the  tire’s  ability  to  stop  on  we t
pavement as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
● Temperature: The temperature grades are A (the highest), B and
C, representing the tire’s res istance to the generation of heat  and
its  ability  to  dissipate  heat  w hen  tested  under  controlled  cond i-
tions on a specified indoor laboratory test wheel.
■Snow Tires
In  some  heavy  snow  areas,  local  governments  may  require  true
snow tires, those with very deeply cut tread. These tires shoul d only
be  used  in  pairs  or  placed  on  all  four  wheels.  Make  sure  you  pu r-
chase  snow  tires  that  are  the  sa me  size  and  construction  type  as
the other tires on your vehicle.
■SAFETY WARNING
The  following  safety  warning  appears  on  the  tire’s  sidewall.  SE RI-
OUS INJURY MAY RESULT FROM: • EXPLOSION  OF  TIRE/RIM  ASSEMBLY  DUE  TO  IMPROPER MOUNTING-MATCH  TIRE  DIAMETER  TO  RIM  DIAMETER;
NEVER  EXCEED  40  psi  (275  kPa)  TO  SEAT  BEADS-ONLY
SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
• TIRE  FAILURE  DUE  TO  UNDE R-INFLATION/OVERLOADING/
DAMAGE-FOLLOW  OWNER’S  MANUAL  AND  PLACARD  IN
VEHICLE-FREQUENTLY CHECK INFLATION PRESSURE AND
INSPECT FOR DAMAGE.

● 11 5
“115”  is  the  nominal  width  of  th e  tire  in  millimeters. This  three-digit
number gives the width in millimet ers of the tire from sidewall edge
to  sidewall  edge.  In  general,  the  larger  the  number,  the  wider  the

● 70
“70”  is  the  aspect  ratio.  This  two-digit  number  indicates  the  t ire’s
ratio of height to width.
● D
“D”  is  the  tire  construction  symbol.  D  indicates  “diagonal  ply  con-
struction”.
● 16
