Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of
the vehicle .
Groove
means the space between two adjacent tread
ri bs.
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflat ion pressure . You
may not find this information on all tires be­
cause it is not requ ired by law .
Ma ximum load rating
means the load rating for a t ire at the max i­
mum permissible inflation pressure for that
tire .
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capac ity weight, and
(d) Production opt ions weight
Ma ximum (permissible) inflation pressure
means the maximum co ld inf lation pressure
to which a tire may be inflated . Also called
"maximum inflation pressure."
Normal occupant weight
means 150 lbs. (68 k ilograms) times the
number of occupants seated in the vehicle up
to the tota l seating capacity of yo ur vehicle.
Occupant distribution
means distribution of occupants in a veh icle.
Outer diameter
means the overall diameter of an inflated new
tire .
Overall width
means the linear distance between the exteri­
ors of the sidewalls of an inflated tire, includ­
ing e levations due to labeling, decorations, or
protective bands or ribs .
Tires and wheels 22 7
Ply
means a layer of rubbe r-coated parallel cords.
Production options weight
means the combined weight of those installed
regular production opt ions we ighing over 5
lbs. (2.3 kg) in excess of those standa rd items
which they replace, not previously considered
in curb weight or accessory weight, including
heavy duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
Radial ply tire
means a pneumatic tire in which the ply cords
that extend to the beads are laid at substan­
tially 90 degrees to the centerl ine of the
tread.
Recommended inflation pressure
see ~ page 226, Cold tire inflation pressure .
Reinforced tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
responding standard tire . Reinforced tires
may be identified as "XL", "xl", "EXTRA LOAD",
or "RF" on the sidewal l.
Rim
means a metal support for a tire or a tire and
tube assembly upon which the tire beads are
seated .
Rim diamete r
means nominal diameter of the bead seat. If
you change your wheel s ize, you wi ll have to
purchase new tires to match the new r im di­
ameter.
Rim size designation
means rim diameter and width.
Rim width
means nominal distance between rim flanges.
Sidewall
means that portion of a tire between the
tread and bead .

nize the load condition of your vehicle.
The effectiveness of the tire pressu re monito r­
ing system w ill be impaired if you store nor­
mal load pressures but then operate the vehi ­
cle at its maximum load¢.&. .

24 4 T ire s and wheel s
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
telltale after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 161 Ins trumen t cluste r: ind icato r light w it h m es­
s age
Using the ABS sensors, the tire pressure moni­
toring system compa res the tire tread circum­
ference and vibration characteristics of the in­
dividual tires .
If the pressure changes in one
or more tires, th is is indicated in the instru­
ment cluster display with an indicator light
IE and a message ¢ fig. 161 . If only one t ire
is affected, the location of that t ire will be in­
d icated. The message turns off after a few mi­
nutes. You can disp lay the message again
¢ page 28.
The tire pressures must be stored in the menu
d isplay aga in each time the pressures change
(switching between part ia l and full load pres­
sure) or after chang ing or replac ing a tire on
your ve hicle ¢
page 245. The tire pressure
monitoring system on ly monitors the ti re
press ure you have stored . You can find the rec­
ommended tire pressures for your vehicle on the
labe l on the driver's doo r pillar
¢ page 229 .
Tire tread circumference and vib ration charac­
teristics can change and cause a tire pressure
warning if:
- I f the tire pressure in one or more ti res is
t oo low.
- The tire has structural damage.
- The tire was replaced or the t ire pressure
changed and it was not stored again
¢ page 245.
-The spare tire is installed .

Check the tires and replace or repair if neces­
sary. Check/correct the pressures of all four
t ires . Then store the t ire pressures in the
menu display

A WARNING
--- If the tire pressure ind icator appears in
the instrument cluster display , one or
mo re of your t ires is sign ifi cant ly unde r­
i n flated. Reduce yo ur speed immedi ately
an d avoid any hard steer ing or b rak ing
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In­
f late the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
