224 Tires and wheels
Gross Vehicle Weight Rating ("GVWR" )
means the maximum total loaded weight o f
the vehicle.
Groove
means the space between two adjacent tread
ribs.
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 informat ion 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 maxi
mum permissible inflation pressure for that
tire .
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity we ight, and
(d) Production opt ions weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressure
to which a tire may be inflated . Also called
"maximum inflation pressure."
Normal occupant weight
means 150 lbs. (68 kilog rams) times the
number of occupants seated in the vehicle up
to the tota l seating capacity of your vehicle.
Occupant distribution
means dist ribution 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 elevations due to labeling, decorations, or
protective bands or ribs .
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
wh ich they replace, not previously cons idered
in curb weight or accessory weight, including
heavy duty brakes, ride levelers, roof rack,
heavy duty battery, and special tr im.
Radial ply tire
means a pneumat ic tire in which the ply cords
that extend to the beads are laid at substan
tially 90 deg rees to the center line of the
tread.
Recommended inflation pressure
see c:::> page 223, 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 sidewall.
Rim
means a metal support for a tire or a t ire and
tube assembly upon which the tire beads are
seated .
Rim diameter
means nominal diameter of the bead seat. If
you change your wheel s ize, you w ill have to
purchase new tires to match the new rim di
ameter .
Rim size designation
means rim diameter and width.
Rim width
means nom inal 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 monitor
ing system* will be impaired if you store nor
mal load pressures but then operate the vehi
cle at its maximum load¢,&.

XL= reinfo rced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire side-
wall.
The correct tire pressure for the spare wheel is
lo cated on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during t he model year, al
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be
l ongs to someone else or you bought the vehi- cle
with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on making sure that
l oad lim its are not exceeded. Vehicle load in
cludes everybody and everything in and on the
vehicle. These load limits are techn ically refer
red to as the veh icle's Gross Vehicle Weight
Rat ing ("GVWR"). The Gross Axle Weight Rat
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .

When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace
ment or alternate tires or whee ls on the veh i
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r replacing one o r more t ires or
wheels on your veh icle to ensure that the re
p lacemen t or a lternate tires and wheels allow
the TPMS to continue to function properly .
Tire pressure 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.
Fig. 173 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni
toring system compares the t ire tread circum
ference and vibration characteristics of the in
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indica ted in the instru
ment clus ter with a
RE wa rning symbol and a
message¢
fig. 173 . The driver message in the
disp lay goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The ti re pressu re monitoring system must be
reset via radio or MMI* each time the pres
sures are adjusted (e.g . when switching be
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle

tors the tire pressure that you have prev iously

T ire tread circum ference and vibration charac
teristics can change and cause a tire pressure

A WARNING
-=
-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is significant ly under
inflated. Reduce your speed immediately
and avoid any hard steer ing or b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In
flate the tire pressure to the prope r pres
sure as indicated on the vehicle's tire
