Federal law mandates that tire manufacturers place standardized information on the side-wall of all tires (see the illustration). The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 1
. See page 336 for more
information about these tires).
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example,
a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maxi-
mum speed at which the tire is designedto be driven for extended periods of time,carrying a permissible load for the vehi-cle, and with correct inflation pressure.For example, H indicates a speed ratingof 130 mph (210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare not required by law.
7. M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN)
: This begins with the letters "DOT"
and indicates that the tire meets all fed- eral standards. The next two numbers orletters are the plant code where it wasmanufactured, the next two are the tiresize code and the last four numbers rep-resent the week and year the tire wasbuilt. For example, 1510 means that thetire was manufactured during week 15 of2010. The numbers in between are mar-keting codes used at the manufacturer'sdiscretion. This information helps a tiremanufacturer identify a tire for safetyrecall purposes.
9. Tire Ply Composition and Material Used
: Indicates the number of plies indi-
cates or the number of layers of rubber- coated fabric in the tire tread and side-wall. Tire manufacturers also must indi-cate the ply materials in the tire and thesidewall, which include steel, nylon, poly-ester, and others.

Tire Pressure Monitoring System (TPMS)
08
336* Option/accessory, for more information, see Introduction.
NOTE
• If you change to tires with a different recommended inflation pressure, theTPMS system must be recalibrated tothese tires. On U.S. models, this mustbe done by a trained and qualifiedVolvo service technician. On Canadianmodels, see the following section"Recalibrating TPMS."
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
Recalibrating TPMS (Canadian models only)*
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 316), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. This is done in the vehicle's menu system. See page 209 for a description of the menusystem. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and put the ignition in mode I or II (see
page 89 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Press OK/MENU , select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 10 minutes.
> When the calibration message is nolonger displayed, TPMS has been recalibrated to the new inflation pres-sure.
Activating/deactivating TPMS
(Canadian models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
89 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select

4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.
