WHEELS AND TYRES

TyresAmongst other things, the function of the tyres is to carry load, provide grip on the road surface,dampen vibration and protect the wheel fromwear.
The tyres greatly affect the car's driving characte- ristics. The type of tyre, dimensions, tyre pressureand speed rating are important for how the carperforms.
Recommended tyresOn delivery, the car is equipped with Volvo origi- nal tyres that have the VOL 1
marking on the side
of the tyres. These tyres are carefully adapted to the car. In the event of changing tyres, it is there-fore important that the new tyres also have thismarking in order for the car's driving characteris-tics, comfort and fuel consumption to be main-tained.
New tyres
Tyres are perishable. After a few years they begin to harden at the same time as the frictioncapacity/characteristics gradually deteriorate. Forthis reason, aim to get as fresh tyres as possiblewhen you replace them. This is especially impor-tant with regard to winter tyres. The last four dig-its in the sequence mean the week and year ofmanufacture. This is the tyre's DOT marking(Department of Transportation), and this is statedwith four digits, for example 0715. The tyre in thefigure was manufactured in week 07 of 2015.
Tyre ageAll tyres older than 6 years old should bechecked by an expert even if they seem undam-aged. Tyres age and decompose, even if they arehardly ever or never used. The function cantherefore be affected. This applies to all tyres that are stored for future use. Examples of externalsigns which indicate that the tyre is unsuitable foruse are cracks or discoloration.
Wear and maintenanceCorrect tyre pressure results in more even wear.Driving style, tyre pressure, climate and road con-dition affect how quickly the tyres age and wear. To avoid differences in tread depth and to pre- vent wear patterns forming on the tyres, the frontand rear wheels can be switched with each other.A suitable distance for the first change is approx.5000 km and then at 10000 km intervals. Volvo recommends the an authorised Volvo work- shop is contacted for checking if you are uncer-tain about tread depth. If significant differences inwear (> 1 mm difference in tread depth) betweentyres have already occurred, then the least worntyres must always be fitted on the rear. Under-steer is normally easier to correct than oversteer,and leads to the car continuing forwards in astraight line rather than having the rear end skid-ding to one side, resulting in possible completeloss of control over the car. This is why it isimportant for the rear wheels never to lose gripbefore the front wheels.
WARNING
A damaged tyre may lead to loss of control over the car.

Tyres' rotation direction
Tyres with a tread pattern which are designed to only turn in one direction have the direction ofrotation marked with an arrow.
The arrow shows the tyre's direction of rotation.
The tyre must always rotate in the same direction throughout its lifespan. Tyres should only beswitched between front and rear positions, neverbetween left and right-hand sides, or vice versa. Ifthe tyres are fitted incorrectly, the car's brakingcharacteristics and capacity to force rain andslush out of the way are adversely affected. Tyreswith the greatest tread depth should always befitted to the rear of the car (to decrease the riskof skidding).
NOTE
Make sure that both pairs of wheels have the same type and dimension, and also the samemake.

Tread wear indicators on the tyres Tread wear indicators show the status of the tyre's tread depth.
A tread wear indicator is a narrow elevation across the longitudinal grooves of the tyre's treadpattern. On the side of the tyre are the lettersTWI (Tread Wear Indicator). When the tyre's treaddepth is down to 1.6 mm, the tread will be level inheight with the tread wear indicators. Change tonew tyres as soon as possible. Remember thattyres with little tread depth provide very poor gripin rain and snow.

Checking the tyre pressures Tyres with the correct air pressure increase driv- ing safety, save fuel and extend the service life ofthe tyres.
Tyre pressure decreases over time, this is a natu- ral phenomenon. Tyre pressure also variesdepending on ambient temperature. Inadequatetyre pressure increases fuel consumption, short-ens tyre lifespan and impairs the car's drivingcharacteristics. Driving on tyres with tyre pressurethat is too low could result in the tyres overheat-ing and being damaged. Tyre pressure affectstravelling comfort, road noise and driving charac-teristics.
Recommended tyre pressure
The tyre pressure label on the driver's side door pillar (between frame and rear door) shows which pressures the tyres should have at different loadsand speed conditions.
Improved fuel economy with ECO pressure
For a light load (max. 3 people) and a speed of up to 160 km/h (100 mph), the ECO pressurescan be chosen for optimum fuel economy. How-ever, the lower comfort pressures are recom-mended instead if optimum noise and travellingcomfort are desired.
Checking the air pressure1. Check the tyre pressures monthly. Carry out
the check on cold tyres, which means thatthe tyres should have the same temperatureas the outside temperature. After several fewkilometres of driving, the tyres warm up andthe pressure increases.
2. If necessary, inflate so that the air pressure corresponds with the approved tyre pressurein accordance with the tyre pressure label.
NOTE
• After a tyre has been inflated, always refit the dust cap in order to avoid damage tothe valve from gravel, dirt, etc.
• Only use plastic dust caps. Metal dustcaps can rust and become difficult tounscrew.

Tyre monitoring
*
The tyre monitoring system, Indirect Tyre Pressure Monitoring System (ITPMS), gives awarning with an indicator symbol in the driverdisplay when the pressure in one or more of thecar's tyres is too low.
If the symbol first flashes for approximately one minute and then changes to a constant glow, itmay indicate that the system cannot detect orwarn of low tyre pressure as intended.
Symbol Specification
•The symbol illuminates in the event of low tyre pressure.
• The symbol flashes for approxi-mately one minute and thenchanges over to illuminatingwith a constant glow in theevent of a fault in the ITPMSsystem.
System descriptionITPMS measures differences in rotation speed between the different wheels via the ABS systemin order to be able to determine whether they have the correct tyre pressure. If the tyre pres-sure is too low, the tyre's diameter is changedand, as a result, so is its rotation speed. By com-paring the tyres with each other the system candetermine whether one or more tyres have pres-sure that is too low. When the tyre pressure is too low, the indicatorsymbol for low tyre pressure is illuminated in thedisplay and a message is shown, see also theheading "Message in the driver display" below.

General information on the tyre monitoring system
In the information below, the tyre monitoring sys- tem is referred to generically as TPMS. Each tyre, including the spare tyre *, should be
checked once a month. When checking, the tyre should be cold and have the air pressure recom-mended by the car manufacturer specified on thetyre pressure label or in the tyre pressure table. Ifthe car has tyres of a different size than that rec-ommended by the manufacturer, find out whatthe correct air pressure level is for these. As an extra safety feature, the car is equipped with a tyre pressure monitoring system (TPMS),which shows when the air pressure in one ormore tyres is too low. When the indicator symbolfor low air pressure is lit, stop and check the tyresas soon as possible and inflate to the correct airpressure. Driving with tyres that have tyre pressure that is too low may cause the tyre to overheat, whichcan cause a puncture. Low tyre pressure alsoreduces fuel efficiency as well as tyre service life,and can affect car handling and stopping ability.Note that TPMS does not replace regular tyremaintenance. It is the driver's responsibility tomaintain correct tyre pressure, even if the limit forlow tyre pressure has not been reached so thatthe indicator symbol illuminates. The car is also equipped with a TPMS system fault indicator, which indicates when the system is not functioning correctly. The TPMS systemfault indicator is combined with the indicator sym-bol for low tyre pressure. When the systemdetects a fault, the symbol in the driver displaywill flash for about one minute and then remainilluminated. This procedure will be repeated whenthe car is started until the fault has been rectified.When the symbol is illuminated, the system's abil-ity to detect or warn of low tyre pressure may beaffected. A TPMS system fault can occur for several rea- sons, such as after changing to a spare tyre, orchanging tyres or wheels that prevent TPMS fromfunctioning correctly. Always check the indicator symbol for TPMS after changing one or more tyres in order toensure the new tyre or wheel is working correctlywith TPMS.
Messages in the driver displayThe following messages may be shown when theindicator symbol is illuminated:
•
Tyre pressure low Check tyres, calibrate
after fill
•Tyre pressure system Temporarily
unavailable
•Tyre pressure system Service required.
If the system cannot determine which tyre has low pressure, all four tyres will be indicated in thecentre display.
To bear in mind
• Always calibrate the system after a wheelchange or tyre pressure adjustment. See thetyre pressure label on the driver's side doorpillar for Volvo's recommended tyre pres-sures.
• The system does not replace normal tyremaintenance.
• There is no option to deactivate ITPMS.
