TIRE REPLACEMENT
REQUIREMENTS
AGE
WARNING: Tires degrade overtime depending on many factors suchas weather, storage conditions, andconditions of use (load, speed, inflationpressure) the tires experiencethroughout their lives.In general, tires should be replacedafter six years regardless of treadwear. However, heat caused by hotclimates or frequent high loadingconditions can accelerate the agingprocess and 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 if ithas not been used.
U.S. DOT Tire Identification Number
Both United States and Canada Federalregulations require tire manufacturersto place standardized information on thesidewall of all tires. This informationidentifies and describes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT Tire IdentificationNumber for safety standard certificationand in case of a recall.
This begins with the letters DOT andindicates that the tire meets all federalstandards. The next two numbers orletters are the plant code designatingwhere it was manufactured, the next twoare the tire size code and the last fournumbers represent the week and yearthe tire was built. For example, the
numbers 317 mean the 31st week of1997. After 2000, the numbers go to fourdigits. For example, 2501 means the25th week of 2001. The numbers inbetween are identification codes usedfor traceability. This information is usedto contact customers if a tire defectrequires a recall.
Tire Replacement Requirements
Your vehicle is equipped with tiresdesigned to provide a safe ride andhandling capability.
WARNING: Only usereplacement tires and wheels that arethe same size, load index, speedrating, and type as those originallyprovided for your vehicle. Therecommended tire and wheel sizescan be found on the Tire Label on thedriver side door frame or the edge ofthe driver door. If this information isnot found in those locations, or foradditional options, contact yourauthorized dealer. Use of any tire orwheel not recommended, could affect
the safety and performance of yourvehicle, which could result in anincreased risk of loss of vehiclecontrol, vehicle rollover, personalinjury and death.

WARNING: To reduce the risk ofserious injury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewall ofthe tire to set the beads withoutadditional precautions listed below. Ifthe beads do not seat at the maximumpressure indicated, re-lubricate andtry again.
WARNING: For a mountingpressure more than 20 psi (1.38 bar)greater than the maximum pressure,a Ford dealer or other tire serviceprofessional should do the mounting.
WARNING: Always inflate steelcarcass tires with a remote air fill withthe person inflating standing at aminimum of 12 ft (3.66 m) away fromthe wheel and tire assembly.
WARNING: When inflating thetire for mounting pressures up to20 psi (1.38 bar) greater than themaximum pressure on the tire sidewall,the following precautions must betaken to protect the person mountingthe tire:
•Make sure that you have the correcttire and wheel size.
•Lubricate the tire bead and wheelbead seat area again.
•Stand at a minimum of 12 ft (3.66 m)away from the wheel and tireassembly.
•Use both eye and ear protection.
Important: Remember to replace thewheel valve stems when the road tiresare replaced on your vehicle.
It is recommended that the two fronttires or two rear tires generally bereplaced as a pair if the worn tires stillhave usable depth.
To avoid potential Four-Wheel Drive(4WD) malfunction or (4WD) systemdamage, it is recommended to replaceall four tires rather than mixingsignificantly worn tires with new tires.
The tire pressure sensors mounted inthe wheels (originally installed on yourvehicle) are not designed to be used inaftermarket wheels.
The use of wheels or tires notrecommended may affect the operationof your tire pressure monitoring system.
If the tire pressure monitoring systemindicator is flashing, your system ismalfunctioning. Your replacement tiremight be incompatible with your tirepressure monitoring system, or somecomponent of the system may be
damaged.

WARNING: Do not exceed 30 mph(50 km/h). Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: Do not use snow chainson snow-free roads.
WARNING: Only fit snow chains tospecified tires.
WARNING: If your vehicle is fittedwith wheel trims, remove them beforefitting snow chains.
WARNING: If you choose to installsnow tires on your vehicle, they must bethe same size, construction, and load rangeas the original tires listed on the tireplacard, and they must be installed on allfour wheels. Mixing tires of different sizeor construction on your vehicle canadversely affect your vehicle's handlingand braking, and may lead to loss ofvehicle control.
WARNING: Wheels and tires mustbe the same size, load index and speedrating as those originally fitted on thevehicle. Use of any other tire or wheel canaffect the safety and performance of yourvehicle. Additionally, the use ofnon-recommended tires and wheels cancause steering, suspension, axle, transfercase or power transfer unit failure. Followthe recommended tire inflation pressures
found on the Safety ComplianceCertification label, or the Tire Label on theB-Pillar or the edge of the driver door.Failure to follow this instruction could resultin loss of vehicle control, vehicle rollover,or personal injury or death.
Only use snow chains on rear wheels. Installsnow chains in pairs. Do not useself-tensioning snow chains.
Only use snow chains on the followingspecified tire sizes. Only install chains thatare 15mm or less (SAE Class S chains).
•265/70R17

CHECKING THE TIRE PRESSURES
Safe operation of your vehicle requiresthat your tires are properly inflated.Every day before you drive, check yourtires.
At least once a month and before longtrips, inspect each tire and check the tirepressure with a tire gauge. Inflate alltires to the recommended inflationpressure. See Inflating the Tires (page449).
INFLATING THE TIRES
WARNING: Under-inflation is themost common cause of tire failures
and may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rollingresistance, resulting in heat buildup
and internal damage to the tire. It alsomay result in unnecessary tire stress,irregular wear, loss of vehicle controland accidents. A tire can lose up tohalf of its air pressure and not appearto be flat!
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge.Failure to follow this instruction couldresult in personal injury or death.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
Inflate your tires to the recommendedinflation pressure even if it is less thanthe maximum inflation pressureinformation found on the tire. You canfind the tire label with the recommendedtire inflation pressure next to the tire sizeon the B-Pillar or the edge of the driverdoor.
The recommended tire inflation pressureis also found on the Safety ComplianceCertification Label, affixed to either thedoor hinge pillar, door-latch post, or thedoor edge that meets the door-latch onthe B-pillar, or on the edge of the driverdoor.
Failure to follow the tire pressurerecommendations can cause uneventreadwear patterns and adversely affectthe way your vehicle handles.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoringsystem measures the vehicle's tirepressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increases sidewallflexing and rolling resistance, resulting in
heat buildup and internal damage to thetire. It also may result in unnecessary tirestress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance Certification Label(on the door hinge pillar, door-latch postor the door edge that meets the door-latchpost, next to the driver seat) or the TireLabel on the B-Pillar or the edge of thedriver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires of adifferent size than the size indicated on thevehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.

CHANGING A FLAT TIRE
If you get a flat tire when driving, do notapply the brake heavily. nstead, graduallydecrease your speed, hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
Have the flat serviced by an authorizeddealer to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem (page 453). Replace the spare tirewith a road tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.
Note:Only use tire sealants in roadsideemergencies as they may cause damage tothe tire pressure monitoring system sensor.
Note:The tire pressure monitoring systemindicator light illuminates when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheels withtire pressure monitoring sensors must bemounted on this vehicle.

Stowing the Flat or Spare Tire
1.Lay the tire on the ground, near the rearof the vehicle, with the valve stem sidefacing up.
2.Slide the wheel partially under thevehicle and install the retainer throughthe wheel center. You may have toremove the wheel center cap prior topushing the retainer through the centerof the wheel. To remove the center cap,press it off with the jack tool from theinner side of the wheel. Pull on the cableto align the components at the end of thecable.
3.Using the swivel wrench, insert it throughthe access hole behind the third row seatand engage the winch.
4.Turn the swivel wrench clockwise untilthe tire is raised to its stowed positionunderneath the vehicle. The wrenchbecomes harder to turn and the sparetire winch ratchets or slips when the tireis raised to maximum tightness. A clickingsound can be heard from the winchindicating that the tire is properly stowed.
5.Carefully place all tools back into the toolkit bag.
6.Reinstall the tool kit bag on the jack andtighten the straps.
7.Reinstall the jack properly on the bracketand secure with the wing nut.
8.Close the access hole with the rubberplug.
9.If the vehicle has an access panel,reinstall.
10.Unblock the wheel.
WHEEL NUTS
WARNING: When you install a wheel,always remove any corrosion, dirt orforeign materials present on the mountingsurfaces of the wheel or the surface of thewheel hub, brake drum or brake disc thatcontacts the wheel. Make sure to secureany fasteners that attach the rotor to thehub so they do not interfere with themounting surfaces of the wheel. Installingwheels without correct metal-to-metalcontact at the wheel mounting surfacescan cause the wheel nuts to loosen andthe wheel to come off while your vehicleis in motion, resulting in loss of vehiclecontrol, personal injury or death.
