2008 SUBARU TRIBECA Owners Manual

Example:(6) Load Index: A numerical code
which specifies the maximum load
a tire can carry at the speed
indicated by its speed symbol, at
maximum inflation pressure.
For example,“104 ”means 1,984
lbs (900 kg), “100 ”means 1,764 lbs
(800 kg), “90 ”means 1,323 lbs (600
kg).
WARNING
Load indices apply only to the
tire, not to the vehicle. Putting
a load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire ’s rated
load.
(7) Speed Rating: An alphabetical
system describing a tire ’s capability
to travel at established and prede-
termined speeds.
For example, “H ” means 130 mph (210 km/h).
WARNING
.
Speed ratings apply only to
the tire, not to the vehicle.
Putting a speed rated tire on
any vehicle does not mean
the vehicle can be operated
at the tire ’s rated speed.
.
The speed rating is void if
the tires are worn out, da-
maged, repaired, retreaded,
or otherwise altered from
their original condition. If
tires are repaired, re-
treaded, or otherwise al-
tered, they may not be sui-
table for original equipment
tire designed loads and
speeds.
! Tire Identification Number (TIN)Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of
four groups. Here is a brief review
of the TIN with a breakdown of its individual elements.
(1) Manufacturer
’s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the
week, starting with “01 ”to represent
the first full week of the calendar
year; the second two figures repre-
sent the year. For example, 0101
means the 1st week of 2001.! Other markingsThe following makings are also
placed on the sidewall.!Maximum permissible inflation
pressureThe maximum cold inflation pres-
sure to which this tire may be
inflated. For example, “300 kPa
(44 PSI) MAX. PRESS ”.

!Maximum load ratingThe load rating at the maximum
permissible weight load for this tire.
For example, “MAX. LOAD 730 kg

WARNING
Maximum load rating applies
only to the tire, not to the
vehicle. Putting a load rated
tire on any vehicle does not
mean the vehicle can be
loaded up to the tire ’s rated
load.! Construction typeApplicable construction of this tire.
For example, “TUBELESS STEEL

material used in the plies (both
sidewall and tread area) of this tire.

!Vehicle placardThe vehicle placard is affixed to the
driver ’s side B-pillar.Example:
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.! Adverse safety consequences
of under-inflationDriving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to an
accident.!Measuring and adjusting air
pressure to achieve proper in-
flationCheck and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to
adjust the tire pressures to the specific values. Driving even a
short distance warms up the tires
and increases the tire pressures.
Also, the tire pressures are affected
by the outside temperature. It is
best to check tire pressure out-
doors before driving the vehicle.
When a tire becomes warm, the air
inside it expands, causing the tire
pressure to increase. Be careful not
to mistakenly release air from a
warm tire to reduce its pressure.

Tire care –maintenance and
safety practices.
Check on a daily basis that the
tires are free from serious damage,
nails, and stones. At the same time,
check the tires for abnormal wear.
.
Inspect the tire tread regularly
and replace the tires before their
tread wear indicators become visi-
ble. When a tire ’s tread wear
indicator becomes visible, the tire
is worn beyond the acceptable limit
and must be replaced immediately.
With a tire in this condition, driving
at even low speeds in wet weather
can cause the vehicle to hydro-
plane. Possible resulting loss of
vehicle control can lead to an
accident.
.
To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the

Consumer information and Reporting safety defects
tires every 7,500 miles (12,000 km).
Rotating the tires involves switch-
ing the front and rear tires on the
right-hand side of the vehicle and
similarly switching the front and
rear tires on the left-hand side of
the vehicle. (Each tire must be kept
on its original side of the vehicle.)
Replace any damaged or unevenly
worn tire at the time of rotation.
After tire rotation, adjust the tire
pressures and make sure the wheel
nuts are correctly tightened. A
tightening torque specification and
a tightening sequence specification
for the wheel nuts can be found
“Flat tires”in chapter 9.& Vehicle load limit –how to
determineThe load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the
vehicle placard attached to the
driver ’s side B-pillar. Locate the
statement “The combined weight of occupants and cargo should
never exceed XXX kg or XXX lbs
”
on your vehicle ’s placard.
Thevehicleplacardalsoshows
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all pas-
sengers and their belongings, any
cargo, any optional equipment such
as a trailer hitch, roof rack or bike
carrier, etc., and the tongue load of
a trailer. Therefore cargo capacity
can be calculated by the following
method.
Cargo capacity = Load limit −(total
weight of occupants + total weight
of optional equipment + tongue
load of a trailer (if applicable))
For towing capacity information and
weight limits, refer to “
Trailer towing”
section in chapter 8.
! Calculating total and load ca-
pacities varying seating con-
figurations
Calculate the available load capa-
city as shown in the following examples:
Example 1AVehicle capacity weight of the
vehicle is 1,157 lbs (525 kg), which
is indicated on the vehicle placard
with the statement
“The combined
weight of occupants and cargo
should never exceed 525 kg or
1,157 lbs ”.
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
plus cargo weighing 882 lbs (400
kg).1.
Calculate the total weight.
ProCarManuals.com

2.
Calculate the available load ca-
pacity by subtracting the total
weight from the vehicle capacity
weight of 1,157 lbs (525 kg).
3.
The result of step 2 shows that a
further 121 lbs (55 kg) of cargo can
be carried.
Example 1BFor example, if a person weighing
176 lbs (80 kg) now enters the
same vehicle (bringing the number
of occupants to two), the calcula-
tions are as follows:1.
Calculate the total weight.
2.
Calculate the available load ca-
pacity.
3.
The total weight now exceeds
the capacity weight by 55 lbs (25
kg), so the cargo weight must be
reduced by 55 lbs (25 kg) or more.

vehicle is 1,157 lbs (525 kg), which
is indicated on the vehicle placard
with the statement“The combined
weight of occupants and cargo
should never exceed 525 kg or
1,157 lbs ”.
For example, the vehicle has one
occupant weighing 165 lbs (75 kg)
plus cargo weighing 705 lbs (320
kg). In addition, the vehicle is fitted
with a trailer hitch weighing 22 lbs
(10 kg), to which is attached a
trailer weighing 1,764 lbs (800 kg).
10% of the trailer weight is applied
to the trailer tongue (i.e. Tongue
load = 176 lbs (80 kg)).1.
Calculate the total weight.
2.
Calculate the available load ca-
pacity.
3.
The result of step 2 shows that a
further 88 lbs (40 kg) of cargo can
be carried.
Example 2BFor example, if a person weighing
143 lbs (65 kg) and a child weighing 40 lbs (18 kg) now enter the same
vehicle (bringing the number of
occupants to three), and a child
restraint system weighing 11 lbs (5
kg) is installed in the vehicle for the
child to use, the calculations are as
