GLOSSARY OF TIRE
TERMINOLOGY
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) andfor Metric tires 36 psi (2.5 bar).Increasing the inflation pressurebeyond this pressure will not
increase the tire’s load carryingcapability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.
*kPa: Kilopascal, a metric unit ofair pressure.
*PSI: Pounds per square inch, astandard unit of air pressure.
*Cold tire pressure: The tirepressure when the vehicle hasbeen stationary and out of directsunlight for an hour or more andprior to the vehicle being driven for1 mi (1.6 km).
*Recommended inflationpressure: The cold inflationpressure found on the SafetyCompliance Certification Label(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or Tire Label located onthe B-Pillar or the edge of thedriver door.
* B-pillar: The structural memberat the side of the vehicle behindthe front door.
*Bead area of the tire: Area ofthe tire next to the rim.
* Sidewall of the tire: Areabetween the bead area and thetread.

WARNING: Only usereplacement tires and wheelsthat are the same size, loadindex, speed rating and type(such as P-metric versusLT-metric or all-season versusall-terrain) as those originallyprovided by Ford. Therecommended tire and wheelsize may be found on either theSafety Compliance CertificationLabel (affixed to either the doorhinge pillar, door-latch post, orthe door edge that meets thedoor-latch post, next to thedriver's seating position), or theTire Label which is located onthe B-Pillar or edge of thedriver's door. If this informationis not found on these labels, thenyou should contact yourauthorized dealer as soon aspossible. Use of any tire or wheelnot recommended by Ford canaffect the safety andperformance of your vehicle,which could result in anincreased risk of loss of vehiclecontrol, vehicle rollover, personalinjury and death.
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: 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.
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:

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.
2. Remove the cap from the valveon one tire, then firmly press thetire gauge onto the valve andmeasure 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 sparewheel and tire assemblyinformation for a description. Storeand maintain at 60 psi(4.15 bar)60 psi (4.15 bar). Forfull-size and dissimilar spare tires,see the Dissimilar spare wheel andtire assembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
Note:Do not reduce tire pressureto change the ride characteristicsof the vehicle. If you do notmaintain the inflation pressure atthe levels specified by Ford, yourvehicle may experience a conditionknown as shimmy. Shimmy is asevere vibration and oscillation inthe steering wheel after the vehicletravels over a bump or dip in theroad that does not dampen out byitself. Shimmy may result fromsignificant under-inflation of thetires, improper tires (load range,size, or type), or vehiclemodifications such as lift-kits. Inthe event that your vehicleexperiences shimmy, you shouldslowly reduce speed by either liftingoff the accelerator pedal or lightlyapplying the brakes. The shimmywill cease as the vehicle speeddecreases.

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, during
any procedure involving tireinflation, the technician orindividual must utilize a remoteinflation device, and ensure thatall persons are clear of thetrajectory area.
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.

WARNING: Do not spin thewheels at over 34 mph(55 km/h). The tires may fail andinjure a passenger or bystander.
HIGH SPEED DRIVING CAN BEDANGEROUS
Correct inflation pressure isespecially important. However, athigh speeds, even with the correctinflation pressure, a road hazardfor example is more difficult toavoid and if contact is made, hasa greater chance of causing tiredamage than at a lower speed.Moreover, driving at high speedreduces the reaction timeavailable to avoid accidents andbring your vehicle to a safe stop.
If you see any damage to a tire orwheel, replace it with the spare atonce and visit a participating TireRetailer.
Exceeding the maximum speedsshown on the following page foreach type of tire will cause the tireto build up excessive heat whichcan cause tire damage that couldresult in sudden tire destructionand rapid air loss. Failure tocontrol a vehicle when one ormore tires experience a sudden airloss can lead to an accident.
In any case, you should notexceed reasonable speeds asindicated by the legal limitsand driving conditions.
DO NOT OVERLOAD: DRIVINGON ANY OVERLOADED TIRE ISDANGEROUS
The maximum load rating of yourtires is molded on the tire sidewall.Do not exceed this rating. Followthe loading instructions of themanufacturer of your vehicle andthis will ensure that your tires arenot overloaded. Tires which areloaded beyond their maximumallowable loads for the particularapplication will build up excessiveheat that may result in sudden tiredestruction. Do not exceed thegross axle weight rating for anyaxle on your vehicle.
TIRE ALTERATIONS
Do not make or allow to be made
any alterations on your tires.Alterations may prevent properperformance, leading to tiredamage which can result in anaccident. Tires which becomeunserviceable due to alterationssuch as truing, whitewall inlays,addition of balancing or sealantliquids, or the use of tire dressingcontaining petroleum distillatesare excluded from warrantycoverage.

FOLLOW THESE MOUNTINGRECOMMENDATIONS
Tire changing can be dangerousand must be done byprofessionally trained personsusing proper tools andprocedures as specified by theUS Tire ManufacturersAssociation (USTMA). Singleor dual assemblies must becompletely deflated beforedemounting.
Your tires should be mounted onwheels of correct size and typeand which are in good, cleancondition. Wheels that are bent,chipped, rusted (steel wheels) orcorroded (alloy wheels) maycause tire damage. The inside ofthe tire must be free from foreignmaterial. Have your retailer checkthe wheels before mounting newtires. Mismatched tires and rimscan explode during mounting.Also, mismatched tires and rimscan result in dangerous tire failureon the road. If a tire is mounted byerror on the wrong-sized rim, donot remount it on the proper rim -scrap it. It may have beendamaged internally (which is notexternally visible) by having beendangerously stretched and couldfail on the highway.
Old valves may leak. When newtubeless tires are mounted,have new valves of the correcttype installed. Tubeless tiresmust only be mounted onwheels designed for tubelesstires i.e., wheels which havesafety humps or ledges.
It is recommended that you haveyour tires and wheels balanced.Tires and wheels, which are notbalanced, may cause steeringdifficulties, a bumpy ride, andirregular tire wear.
Be sure that all your valveshave suitable valve caps. Thevalve cap is the primary sealagainst air loss.
TEMPORARY SPARE TIRES
When using any temporary sparetire, be sure to follow the vehiclemanufacturer’s instructions.
REMEMBER... TO AVOIDDAMAGE TO YOUR TIRES ANDPOSSIBLE ACCIDENT:
•CHECK TIRE PRESSURE ATLEAST ONCE EACH MONTHWHEN TIRES ARE COLD ANDBEFORE LONG TRIPS.
•DO NOTUNDERINFLATE/OVERINFLATE.
•DO NOT OVERLOAD.
•DRIVE AT MODERATESPEEDS, OBSERVE LEGALLIMITS.
