Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, checkyour tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.

At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommendedby Ford Motor Company.
You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Fordrecommends the use of a digitalor dial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns
WARNING: Under-inflationis the most common cause oftire failures and may result insevere tire cracking, treadseparation or blowout, withunexpected loss of vehiclecontrol and increased risk ofinjury. Under-inflation increasessidewall flexing and rollingresistance, resulting in heatbuildup and internal damage tothe tire. It also may result inunnecessary tire stress, irregularwear, loss of vehicle control andaccidents. A tire can lose up tohalf of its air pressure and notappear to be flat!
Always inflate your tires to theFord recommended inflationpressure even if it is less than themaximum inflation pressureinformation found on the tire. TheFord recommended tire inflationpressure is found on the SafetyCompliance Certification Label orTire Label. See the completedvehicle's owner's manual for thelocation of the Safety ComplianceCertification Label or Tire Label.Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles
Maximum Inflation Pressure isthe tire manufacturer's maximumpermissible pressure and thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe manufacturer’s recommendedcold inflation pressure which canbe found on the SafetyCompliance Certification Label orTire Label. See the completedvehicle's owner's manual for thelocation of the Safety ComplianceCertification Label or Tire Label.The cold inflation pressure shouldnever be set lower than therecommended pressure on theSafety Compliance CertificationLabel or Tire Label.

When weather temperaturechanges occur, tire inflationpressures also change. A 10°F(6°C) temperature drop cancause a corresponding drop of 1psi (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 pressthe tire 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, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat 60 psi (4.15 bar). For full-sizeand dissimilar spare tires, see theDissimilar spare wheel and tireassembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6.Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tireand cause an air leak.
7.Check the sidewalls to makesure there are no gouges, cutsor bulges.

Tire Inflation Information
WARNING: An inflated tireand rim can be very dangerousif improperly used, serviced ormaintained. To reduce the riskof serious injury, never attemptto re-inflate a tire which hasbeen run flat or seriouslyunder-inflated without firstremoving the tire from the wheelassembly for inspection. Do notattempt to add air to tires orreplace tires or wheels withoutfirst taking precautions toprotect persons and property.
All tires with Steel Carcass Plies(if equipped):
This type of tire utilizes steel cordsin the sidewalls. As such, theycannot be treated like normal lighttruck tires. Tire service, includingadjusting tire pressure, must beperformed by personnel trained,supervised and equippedaccording to Federal OccupationalSafety and Health Administrationregulations. For example, duringany procedure involving tireinflation, the technician orindividual must utilize a remoteinflation device, and ensure thatall persons are clear of thetrajectory area.

Tire Wear
When the tread is worn down toone sixteenth of an inch (2millimeters), tires must bereplaced to help prevent yourvehicle from skidding andhydroplaning. Built-in treadwearindicators, or wear bars, whichlook like narrow strips of smoothrubber across the tread willappear on the tire when the treadis worn down to one sixteenth ofan inch (2 millimeters).
When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.
Damage
Periodically inspect the tire treadsand sidewalls for damage (suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread orsidewall). If damage is observed
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 degradeover time depending on manyfactors such as weather, storageconditions, and conditions of use(load, speed, inflation pressure)the tires experience throughouttheir lives.
WARNING: In general, tiresshould be replaced after sixyears regardless of tread wearor even if they have not beenused. However, heat caused byhot climates or frequenthigh-load conditions canaccelerate the aging process andmay require you to replace tiresmore frequently.
WARNING: You shouldreplace your spare tire when youreplace the road tires or after sixyears due to aging even if it hasnot been used.

WARNING: To reduce therisk of serious injury, whenmounting replacement tires andwheels, you should not exceedthe maximum pressure indicatedon the sidewall of the tire to setthe beads without additionalprecautions listed below. If thebeads do not seat at themaximum pressure indicated,re-lubricate and try again.
WARNING: When inflatingthe tire for mounting pressuresup to 20 psi (1.38 bar) greaterthan the maximum pressure onthe tire sidewall, the followingprecautions must be taken toprotect the person mounting thetire:
WARNING: 1. Make surethat you have the correct tireand wheel size.
WARNING: 2. Lubricate thetire bead and wheel bead seatarea again.
WARNING: 3. Stand at aminimum of 12 ft (3.66 m) awayfrom the wheel and tireassembly.
WARNING: 4. Use both eyeand ear protection.
WARNING: For a mountingpressure more than 20 psi(1.38 bar) greater than themaximum pressure, a Forddealer or other tire serviceprofessional should do themounting.
WARNING: Always inflatesteel carcass tires with a remoteair fill with the person inflatingstanding at a minimum of 12 ft(3.66 m) away from the wheeland 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.
Replacing a Tire That isGreenhouse Gas Certified

Tire Rotation
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.
Dual rear wheel drive vehicle - sixtire rotation
If your vehicle is equipped withdual rear wheels it isrecommended that the front andrear tires (in pairs) be rotated onlyside to side. We do notrecommend splitting up the dualrear wheels. Rotate them side toside as a set. After tire rotation,inflation pressures must beadjusted for the tires newpositions in accordance withvehicle requirements.
Sometimes irregular tire wear canbe corrected by rotating the tires.
