2018 FORD FOCUS wheel size

When weather temperaturechanges occur, tire inflationpressures also change. A 10°F(6°C) temperature drop cancause a corresponding drop of1 psi (7 kPa) in inflation pressure.Check your tire pressuresfrequently and adjust them to theproper pressure which can befound on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in yourtire(s):
1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
Note:If you are checking tirepressure when the tire is hot, (forexample, driven more than 1 mile[1.6 kilometers], never bleed orreduce air pressure. The tires arehot from driving and it is normal forpressures to increase aboverecommended cold pressures. Ahot tire at or below recommendedcold inflation pressure could besignificantly under-inflated.
Note:If you have to drive adistance to get air for your tire(s),check and record the tire pressurefirst and add the appropriate airpressure when you get to thepump. It is normal for tires to heatup and the air pressure inside to goup as you drive.
2. Remove the cap from the valveon one tire, then firmly press thetire gauge onto the valve and
measure the pressure.
3. Add enough air to reach therecommended air pressure.
Note:If you overfill the tire, releaseair by pressing on the metal stemin the center of the valve. Thenrecheck the pressure with your tiregauge.
4. Replace the valve cap.
5. Repeat this procedure for eachtire, including the spare.
Note:Some spare tires operate ata higher inflation pressure than theother tires. For T-type mini-sparetires, refer to the Dissimilar sparewheel and tire assemblyinformation for a description. Storeand maintain at 60 psi (4.15 bar).For full-size and dissimilar sparetires, refer to the Dissimilar sparewheel and tire assemblyinformation for a description. Storeand maintain at the higher of thefront and rear inflation pressure asshown on the Tire Label.
6. Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tire andcause an air leak.
7. Check the sidewalls to makesure there are no gouges, cuts orbulges.

or suspected have the tireinspected by a tire professional.Tires can be damaged duringoff-road use, so inspection afteroff-road use is alsorecommended.
Age
WARNING
Tires degrade over timedepending on many factorssuch as weather, storageconditions, and conditions of use(load, speed, inflation pressure)the tires experience throughouttheir lives.
In general, tires should bereplaced after six years regardlessof tread wear. However, heat
caused by hot climates orfrequent high loading conditionscan accelerate the aging processand may require tires to bereplaced more frequently.
You should replace your spare tirewhen you replace the road tires orafter six years due to aging even ifit has not been used.
U.S. DOT Tire IdentificationNumber
Both United States and CanadaFederal regulations require tiremanufacturers to placestandardized information on thesidewall of all tires. Thisinformation identifies and
describes the fundamentalcharacteristics of the tire and alsoprovides a United States DOT TireIdentification Number for safetystandard certification and in caseof a recall.
This begins with the letters DOTand indicates that the tire meetsall federal standards. The nexttwo numbers or letters are theplant code designating where itwas manufactured, the next twoare the tire size code and the lastfour numbers represent the weekand year the tire was built. Forexample, the numbers 317 meanthe 31st week of 1997. After 2000the numbers go to four digits. Forexample, 2501 means the 25thweek of 2001. The numbers inbetween are identification codesused for traceability. Thisinformation is used to contactcustomers if a tire defect requiresa recall.
Tire ReplacementRequirements
Your vehicle is equipped with tiresdesigned to provide a safe rideand handling capability.
WARNINGS

If thisinformation is not found on theselabels, then you should contactyour authorized dealer as soon aspossible. Use of any tire or wheelnot recommended by Ford canaffect the safety and performanceof your vehicle, which could resultin an increased risk of loss ofvehicle control, vehicle rollover,personal injury and death.
To reduce the risk of seriousinjury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewallof the tire to set the beads withoutadditional precautions listedbelow. If the beads do not seat atthe maximum pressure indicated,re-lubricate and try again.
When inflating the tire formounting pressures up to20 psi (1.38 bar) greater than themaximum pressure on the tiresidewall, the followingprecautions must be taken toprotect the person mounting thetire:
•Make sure that you have thecorrect tire and wheel size.
•Lubricate the tire bead andwheel bead seat area again.
•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
WARNINGS
For a mounting pressuremore than 20 psi (1.38 bar)greater than the maximumpressure, a Ford dealer or othertire service professional should dothe mounting.
Always inflate steel carcasstires with a remote air fill withthe person inflating standing at aminimum of 12 ft (3.66 m) awayfrom the wheel and tire assembly.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
It is recommended that the twofront tires or two rear tiresgenerally be replaced as a pair.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.

Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to becomemisaligned or cause damage toyour tires. If your vehicle seems topull to one side when you aredriving, the wheels may be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer. Front-wheeldrive vehicles and those with anindependent rear suspension (ifequipped) may require alignmentof all four wheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
WARNING
If the tire label showsdifferent tire pressures for thefront and rear tires and the vehiclehas a tire pressure monitoringsystem, then you need to updatethe settings for the systemsensors. Always perform thesystem reset procedure after tirerotation. If you do not reset thesystem, it may not provide a lowtire pressure warning whennecessary.
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to thevehicle requirements.
Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) will helpyour tires wear more evenly,providing better tire performanceand longer tire life.
Front-wheel drive vehicles (fronttires on the left side of thediagram).

Sometimes irregular tire wear canbe corrected by rotating the tires.
USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index and speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of control,vehicle rollover, personal injury and death.Additionally, the use of non-recommendedtires and wheels can cause steering,suspension, axle, transfer case or powertransfer unit failure. Follow the Fordrecommended tire inflation pressure foundon the Safety Compliance CertificationLabel (on the door hinge pillar, door latchpost or the door edge that meets the doorlatch post, next to the driver seat), or TireLabel on the B-Pillar or the edge of thedriver door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns and adverselyaffect the way your vehicle handles.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires or snow chains.
If you choose to install snow tires on yourvehicle, they must be installed on all fourwheels and they must be the same size,load index and speed rating as the originaltires listed on the tire inflation pressurelabel. The label is on the on the B-Pillar orthe edge of the driver door . Mixing tires ofdifferent size or construction on yourvehicle can adversely affect your vehicle’shandling and braking, and may lead to lossof vehicle control.
If you use snow chains, we recommendthat steel wheels of the same size andspecifications are used. Snow chains maydamage aluminum wheels.
Follow these guidelines when using snowchains:
•Avoid fully loading your vehicle.
•Only use small link snow chains ofapproximately 10mm with 215/55R16tires only.
•Only use small link snow chains ofapproximately 15mm with 195/65R15tires only.
•Only use snow chains on the tire sizeslisted above.
•Snow chains must be mounted in pairson the front axle.
•Install snow chains securely, make surethey do not touch any wiring, brakelines or fuel lines.
•Do not exceed 30 mph (48 km/h) orthe maximum speed recommended bythe chain manufacturer, whichever isless.
•Remove snow chains when they are nolonger required.
•Do not use snow chains on dry roads.

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctlymaintain tire pressures could increase therisk of tire failure, loss of control, vehiclerollover and personal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehiclehas been equipped with a Tire PressureMonitoring System (TPMS) thatilluminates a low tire pressure telltalewhen one or more of your tires issignificantly under-inflated. Accordingly,when the low tire pressure telltaleilluminates, you should stop and checkyour tires as soon as possible, and inflate
them to the proper pressure. Driving on asignificantly under-inflated tire causes thetire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiencyand tire tread life, and may affect thevehicle’s handling and stopping ability.
Please note that the TPMS is not asubstitute for proper tire maintenance, andit is the driver’s responsibility to maintaincorrect tire pressure, even if under-inflationhas not reached the level to triggerillumination of the TPMS low tire pressuretelltale.
Your vehicle has also been equipped witha TPMS malfunction indicator to indicatewhen the system is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequencewill continue upon subsequent vehiclestart-ups as long as the malfunction exists.
When the malfunction indicator isilluminated, the system may not be ableto detect or signal low tire pressure asintended. TPMS malfunctions may occurfor a variety of reasons, including theinstallation of replacement or alternatetires or wheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or more tires orwheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to functionproperly.
This device complies with Part 15 of theFCC Rules and with License exempt RSSStandards of Industry Canada. Operationis subject to the following two conditions:
1.This device may not cause harmfulinterference, and

How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. While driving in a normal manner, atypical passenger tire inflation pressuremay increase about 2–4 psi (14–28 kPa)from a cold start situation. If the vehicle isstationary overnight with the outsidetemperature significantly lower than thedaytime temperature, the tire pressure maydecrease about 3 psi (21 kPa) for a drop of30°F (17°C) in ambient temperature. Thislower pressure value may be detected bythe tire pressure monitoring system asbeing significantly lower than therecommended inflation pressure andactivate the system warning light for lowtire pressure. If the low tire pressurewarning light is on, visually check each tireto verify that no tire is flat. If one or moretires are flat, repair as necessary. Checkthe air pressure in the road tires. If any tireis under-inflated, carefully drive the vehicleto the nearest location where air can beadded to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNINGS
Do not use tire sealants as they maydamage the tire pressure monitoringsystem.
If the tire pressure monitor sensorbecomes damaged it may notfunction.
Note:The tire pressure monitoring systemindicator light will illuminate when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on this vehicle.
If you get a flat tire while driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safeplace on the side of the road.
Have a flat serviced by an authorizeddealer in order to prevent damage to thesystem sensors See Tire PressureMonitoring System (page 260). Replacethe spare tire with a road tire as soon aspossible. During repairing or replacing ofthe flat tire, have the authorized dealerinspect the system sensor for damage.
