8. U.S. DOT Tire Identification Number (TIN) : This begins with the letters "DOT" and
indicates that the tire meets all federalstandards. The next two numbers or lettersare the plant code where it was manufac-tured, the next two are the tire size code andthe last four numbers represent the weekand year the tire was built. For example,1510 means that the tire was manufacturedduring week 15 of 2010. The numbers inbetween are marketing codes used at themanufacturer's discretion. This informationhelps a tire manufacturer identify a tire forsafety recall purposes.
9. Tire Ply Composition and MaterialUsed : Indicates the number of plies indi-
cates or the number of layers of rubber-coated fabric in the tire tread and sidewall.Tire manufacturers also must indicate the plymaterials in the tire and the sidewall, whichinclude steel, nylon, polyester, and others.
10. Maximum Load : Indicates the maximum
load in pounds and kilograms that can becarried by the tire. Refer to the vehicle's tireinformation placard located on the B-Pillarfor the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperaturegrades : see Tire specifications – Uniform
Tire Quality Grading (p. 302) for more infor-mation. 12.
Maximum permissible inflationpressure: the greatest amount of air pres-
sure that should ever be put in the tire. Thislimit is set by the tire manufacturer.
Loading specifications Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weightThe weight of the vehicle including a full tank offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weightThe maximum allowable weight that can be car-ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passengers.

Tire specifications – terminologyThe following is a glossary of tire-related terms.
The tire suppliers may have additional markings, notes or warnings such as standard load, radialtubeless, etc.
• Tire information placard
: A placard show-
ing the OE (Original Equipment) tire sizes,recommended inflation pressure, and themaximum weight the vehicle can carry.
• Tire Identification Number (TIN)
: A number
on the sidewall of each tire providing infor-mation about the tire brand and manufactur-ing plant, tire size and date of manufacturer.
• Inflation pressure
: A measure of the
amount of air in a tire.
• Standard load
: A class of P-metric or Metric
tires designed to carry a maximum load at35 psi [37 psi (2.5 bar) for Metric tires].Increasing the inflation pressure beyond thispressure will not increase the tires load car-rying capability.
• Extra load
: A class of P-metric or Metric
tires designed to carry a heavier maximumload at 41 psi [43 psi (2.9 bar) for Metrictires]. Increasing the inflation pressurebeyond this pressure will not increase thetire's load carrying capability.
• kPa

• PSI
: Pounds per square inch, a standard unit
of air pressure. •
B-pillar
: The structural member at the side
of the vehicle behind the front door.

area and the tread.
• Tread area of the tire
: Area of the perime-
ter of the tire that contacts the road whenmounted on the vehicle.
• Rim
: The metal support (wheel) for a tire or a
tire and tube assembly upon which the tirebeads are seated.
• Maximum load rating
: a figure indicating
the maximum load in pounds and kilogramsthat can be carried by the tire. This rating isestablished by the tire manufacturer.
• Maximum permissible inflation pressure
:
the greatest amount of air pressure thatshould ever be put in the tire. This limit is setby the tire manufacturer.
• Recommended tire inflation pressure
:
inflation pressure, established by Volvo,which is based on the type of tires that aremounted on a vehicle at the factory. Thisinformation can be found on the tire inflationplacard(s) located on the driver's side B-pillarand in the tire inflation table in this chapter.
• Cold tires
: The tires are considered to be
cold when they have the same temperatureas the surrounding (ambient) air. This tem- perature is normally reached after the vehiclehas been parked for at least 3 hours.

Tire pressure monitoring - overview
Volvo provides two different systems to monitor tire pressure: Tire Pressure Monitoring System(TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehicle, press the MY CAR button on the center console.
Go to
SettingsCar settings.
• If your vehicle has a menu called
Tire
monitoring, see Tire Monitor - introduction
(p. 305).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring Sys-
tem (TPMS) – general information (p. 308).
IntroductionEach tire, including the spare (if provided), should be checked monthly when cold and inflated tothe inflation pressure recommended by the vehi-cle manufacturer on the vehicle placard or tireinflation pressure label. (If your vehicle has tiresof a different size than the size indicated on thevehicle placard or tire inflation pressure label, youshould determine the proper tire inflation pres-sure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi- cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. System malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle that
WHEELS AND TIRES

prevent the tire pressure monitoring system from functioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Tire Monitor - introduction Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes.By comparing the individual tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:
Tire
pressure low Check tires. Adjust the inflation
pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.

Calibrating Tire Monitor In order for Tire Monitor to work correctly, tire pressure reference values must be set. Thismust be done each time wheels or tire pressuresare changed.
Calibration1. Switch off the engine.
2. Inflate the tires to the desired pressure (con-sult tire pressure placard located on the driv- er's side B-pillar (the structural member atthe side of the vehicle) and put the ignition in mode II, see Ignition modes (p. 80).
3. Press the MY CAR button on the center
console control panel and select
Settings
Car settingsTire monitoring.
4. Press OK/MENU , select
Calibrate tire
pressure and press OK/MENU again after
all of the tires have been checked and rein- flated.
5. Drive away. > The calibration process will be completedwhile driving and will be interrupted if thevehicle is parked and the engine isswitched off. Calibration continues auto-matically when driving resumes. The sys-tem will not give any confirmation whencalibration is finished although it will stateif calibration fails. When driving with heavy loads or at sustainedhighway speeds, the tire pressure should beadjusted to the recommended inflation pressuresaccording to the tire inflation pressure placardlocated on the driver's side B-pillar (the structuralmember at the side of the vehicle, at the rear ofthe driver's door opening) or to the tire inflationpressure table in the owner's information. After adjusting inflation pressure, repeat steps 1-5 above.
NOTE
Always remember to calibrate Tire Monitor when the wheels have been changed or thetire pressure has been corrected according totire pressure placard or tire pressure table. Ifcorrect reference values have not been set,the system cannot issue low tire pressurealerts correctly.
Tire Monitor status information
The current status of the system and the tires is indicated by color-coded graphics.
This status can be displayed by pressing the MY
CAR button on the center console and going to

Tire Monitor – messages
When low tire pressure has been detected, a message will be displayed and the tire pressure warning telltale in the instrument panel (
)
will illuminate.
MessagesIf the telltale illuminates, one of the following message will also be displayed: •
Tire pressure low/Check, adjust and
calibrate
•Tire pressure system/Service required
•Tire pressure system/Currently
unavailable
Erasing warning messagesTo erase a low tire pressure message and turn off the telltale:
1. Use a tire pressure gauge to check the infla- tion pressure of all four tires.
2. Re-inflate the tires to the correct pressure (consult the tire pressure decal on the driv- er's door opening.
3. Recalibrate Tire Monitor, see Calibrating Tire Monitor (p. 306).
NOTE
To help avoid incorrect tire inflation pressure, only inflate the tires when they are cold. Thetires are considered to be cold when theyhave the same temperature as the surround-ing (ambient) air. This temperature is normallyreached after the vehicle has been parked forat least 3 hours. After driving a distance ofapproximately 1 mile (1.6 km), the tires areconsidered to be hot.
CAUTION
• After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
•
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
• Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.

Tire Pressure Monitoring System (TPMS) – general information TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When thevehicle is moving at a speed of approximately20 mph (30 km/h) or faster, these sensorstransmit inflation pressure data to a receiverlocated in the vehicle.
NOTE
USA – FCC ID: KR5S180052050 This device complies with part 15 of the FCC rules. Operation is subject to the followingconditions: (1) This device may not causeharmful interference, and (2) this device mustaccept any interference received, includinginterference that may cause undesired opera-tion.
When low inflation pressure is detected or if a sensor is not functioning properly, TPMS will light up the tire pressure warning light (
) (also
referred to as a telltale) in the instrument panel and will display one of the following messages:
Tire pressure low, Tire needs air now or Tire
press. syst Service required.

Tire Pressure Monitoring System (TPMS) – changing wheels
Please keep the following in mind when chang- ing or replacing the factory installed TPMSwheels/tires on the vehicle:
• Not all aftermarket wheels are equipped withTPMS sensors in the valves.
• If the vehicle is equipped with a temporaryspare tire, this tire does not have a TPMSsensor.
• If wheels without TPMS sensors are moun-ted on the vehicle, a text message will dis-played in the instrument panel each time thevehicle is driven above 20 mph (30 km/h) for10 minutes or more.
• Once TPMS sensors are properly installed,the warning message should not reappear. Ifthe message is still displayed, drive the vehi-cle for several minutes at a speed of 20 mph(30 km/h) or faster to erase the message.
• Volvo recommends that TPMS sensors befitted on all wheels used on the vehicle,including winter tires. Volvo does not recom-mend moving sensors back and forthbetween sets of wheels.
