Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 195 T ire press ure label : located on driver's side B·
pillar
Tire pressure genera lly refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
p art o n the vehicle's design and load limit -
the greatest amount of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
"recommended cold tire inflation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The tir e p ressu re is higher when the tire
has wa rmed up tha n when it is "cold." It is the
in flat ion pressu re i n a "cold" tire that counts.
Therefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire infl ation pres
sure" recommendations . The t ires wo uld then
be underinflated and could fail suddenly.
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you can do to he lp
avoid sudden tire failure. Underin fla ted t ires

i n g tires at the right pressure is also impor

24 6 T ire s and whee ls
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment dur ing the model year, a l
ways compare the tire size designation on the
tire pressure labe l on your vehicle with the
tires on your vehicle . Make sure that the tire
si ze information on the vehicle label is the
same as the si ze of the tires on the vehicle.
This is especially important if the vehicle be
longs to someone else or you bought the veh i
cle with different rims/tires or you bought the
vehicle as a p reviously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on mak ing sure that
l oad limits are not exceeded. Vehicle load in
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
o ther cargo that the vehicle can carry. For the
l ocation of the tire pressu re labe l
i=:> fig. 195.
A WARNING
Overloading a vehicle can cause loss of ve
hicle control, a cras h or other accident, se
r ious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in
crease the risk of a loss of veh icle con
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload
ed can fail suddenly causing loss of con
trol and a crash . -
Always make sure that the total load be
ing transported - including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi
cle heavier than the vehicle's G ross Vehi
cle Weight Rating.
A WARNING
-- I ncorrect tire pressures and/or underin-
flation can lead to a serious or fatal acci
dent.
- I nco rrect tire pressures and/or underin
flation cause increased ti re wear and can
affec t the handling of the vehicle .
- I nco rrect tire pressures and/or underin
flation can a lso lead to s udden t ire fail
ure, including a blowou t and sudden de
flation, ca using loss of veh icle cont ro l.
Checking tire pressure
The correct tire pressure for the tires original
ly installed on your vehicle is listed on the tire
pressur e label located on driver's side 8-pil
lar .
The recommended tire pressures are on the
t ir e pressure label and in the table
i=:> page 244, Cold tire inflation pressure.This
means that the pressure m ust be checked and
adjusted when the t ire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up as a result of inter nal frict ion as it flexes in
u se . T he t ire pressure is higher when the tire
has warmed up t han whe n it is "co ld. "
It is the inflation pressure in a "co ld" t ire that
counts . The refore, you should never let a ir out
of a wa rm tire to match "Cold t ire inflat ion
pressure" recomme ndat ions

t ir es wo uld then be unde rinflated and co uld

Traction
The traction grades, from highest to lowest,

C. Those grades 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¢ .&..
Temp eratu re
The temperature grades are A (the highest),
B, and
C, representing the tire 's resistance to
the generat ion of heat and its ability to dissi
pate heat when tested under controlled condi

wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce

to sudden tire failu re ¢ .&. .
The grade C corresponds to a level of perform

A WARNING
The temperature grade for this t ire is es

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true w inter o r "snow" tir es, those
with very deeply cut t read. These tires should
o nl y be used in pairs and be installed o n all
f o ur wheels . Make sure you p urchase snow

I f your veh icle is eq uipped w ith all-whee l

when winter road condit ions are expected.
This also improves the veh icle 's b rak ing per

Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
