Glossary of Tire Terminology
•Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressure andthe maximum weight the vehicle cancarry.
•Tire Identification Number: Anumber on the sidewall of each tireproviding information about the tirebrand and manufacturing plant, tiresize and date of manufacture. Alsoreferred to as DOT code.
•Inflation pressure: A measure of theamount of air in a tire.
•Standard load: A class of P-metric orMetric tires designed to carry amaximum load at set pressure. Forexample: For P-metric tires 35 psi(2.4 bar) and for Metric tires 36 psi(2.5 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s load carryingcapability.
•Extra load: A class of P-metric orMetric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s load carryingcapability.
•kPa: Kilopascal, a metric unit of airpressure.
•PSI: Pounds per square inch, astandard unit of air pressure.
•Cold tire pressure: The tire pressurewhen the vehicle has been stationaryand out of direct sunlight for an houror more and prior to the vehiclebeing driven for 1 mile (1.6 km).
•Recommended inflation pressure:The cold inflation pressure found onthe Safety Compliance CertificationLabel (affixed to either the doorhinge pillar, door-latch post, or thedoor edge that meets the door-latchpost, next to the driver's seatingposition), or Tire Label located on theB-Pillar or the edge of the driver’sdoor.
•B-pillar: The structural member atthe side of the vehicle behind thefront door
•Bead area of the tire: Area of the tirenext to the rim.
•Sidewall of the tire: Area betweenthe bead area and the tread.
•Tread area of the tire: Area of theperimeter of the tire that contacts theroad when mounted on the vehicle.
•Rim: The metal support (wheel) for atire or a tire and tube assembly uponwhich the tire beads are seated.

F. 95: Indicates the tire's load index. Itis an index that relates to how muchweight a tire can carry. You may find thisinformation in your owner’s manual. Ifnot, contact a local tire dealer.
Note:You may not find this informationon all tires because it is not required byfederal law.
G. H: Indicates the tire's speed rating.The speed rating denotes the speed atwhich a tire is designed to be driven forextended periods of time under astandard condition of load and inflationpressure. The tires on your vehicle mayoperate at different conditions for loadand inflation pressure. These speedratings may need to be adjusted for thedifference in conditions. The ratings
range from 81 mph (130 km/h) to 186mph (299 km/h). These ratings are listedin the following chart.

A. T: Indicates a type of tire, designatedby the Tire and Rim Association, that isintended for temporary service on cars,sport utility vehicles, minivans and lighttrucks.
B. 145: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 80: Indicates the aspect ratio whichgives the tire's ratio of height to width.Numbers of 70 or lower indicate a shortsidewall.
D. D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E. 16: Indicates the wheel or rimdiameter in inches. If you change your
wheel size, you will have to purchasenew tires to match the new wheeldiameter.
Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver’s door.
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before longtrips, inspect each tire and check the tire
pressure with a tire gauge (includingspare, if equipped). Inflate all tires to theinflation pressure recommended by FordMotor Company.

You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. Ford recommends the useof a digital or dial-type tire pressuregauge rather than a stick-type tirepressure gauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns
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 increasessidewall flexing and rolling resistance,resulting in heat buildup and internaldamage to the tire. It also may result inunnecessary tire stress, irregular wear,loss of vehicle control and accidents. A
tire can lose up to half of its air pressureand not appear to be flat!
Always inflate your tires to the Fordrecommended inflation pressure evenif it is less than the maximum inflationpressure information found on the tire.The Ford recommended tire inflationpressure is found on the SafetyCompliance Certification Label (affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver'sseating position), or Tire Label which islocated on the B-Pillar or the edge of thedriver’s door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns andadversely affect the way your vehiclehandles
Maximum Inflation Pressure is the tiremanufacturer's maximum permissible
pressure and the pressure at which themaximum load can be carried by the tire.This pressure is normally higher than themanufacturer’s recommended coldinflation pressure which can be foundon the Safety Compliance CertificationLabel (affixed to either the door hingepillar, door-latch post, or the door edge
that meets the door-latch post, next tothe driver's seating position), or TireLabel which is located on the B-Pillar orthe edge of the driver’s door. The coldinflation pressure should never be setlower than the recommended pressureon the Safety Compliance CertificationLabel or Tire Label.
When weather temperature changesoccur, tire inflation pressures alsochange. A 10°F (6°C) temperature dropcan cause a corresponding drop of 1 psi(7 kPa) in inflation pressure. Check yourtire pressures frequently and adjustthem to the proper pressure which canbe found on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in your tire(s):
1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.

Wheels and Tires

Note:If you are checking tire pressurewhen the tire is hot, (for example drivenmore than 1 mile [1.6 kilometers]), neverbleed or reduce air pressure. The tiresare hot from driving and it is normal forpressures to increase aboverecommended cold pressures. A hot tireat or below recommended cold inflationpressure could be significantlyunder-inflated.
Note:If you have to drive a distance toget air for your tire(s), check and recordthe tire pressure first and add theappropriate air pressure when you getto the pump. It is normal for tires to heatup and the air pressure inside to go upas you drive.
2.Remove the cap from the valve on
one tire, then firmly press the tiregauge onto the valve and measurethe pressure.
3. Add enough air to reach therecommended air pressure.
Note:If you overfill the tire, release airby pressing on the metal stem in thecenter of the valve. Then recheck thepressure with your tire gauge.
4. Replace the valve cap.
5.Repeat this procedure for each tire,including the spare.
Note:Some spare tires operate at ahigher inflation pressure than the othertires. For T type mini-spare tires, see theDissimilar spare wheel and tireassembly information for a description.Store and maintain at 60 psi (4.15 bar).For full-size and dissimilar spare tires,see the Dissimilar spare wheel and tireassembly information for a description.Store and maintain at the higher of thefront and rear inflation pressure as
shown on the Tire Label.
6.Visually inspect the tires to makesure there are no nails or otherobjects embedded that could pokea hole in the tire and cause an airleak.
7. Check the sidewalls to make surethere are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel ValveStems
Periodically inspect the tire treads foruneven or excessive wear and removeobjects such as stones, nails or glassthat may be wedged in the treadgrooves. Check the tire and valve stemsfor holes, cracks, or cuts that may permitair leakage and repair or replace the tireand replace the valve stem. Inspect thetire sidewalls for cracking, cuts, bruisesand other signs of damage or excessivewear. If internal damage to the tire issuspected, have the tire demounted andinspected in case it needs to be repairedor replaced. For your safety, tires that
are damaged or show signs of excessivewear should not be used because theyare more likely to blow out or fail.

Improper or inadequate vehiclemaintenance can cause tires to wearabnormally. Inspect all your tires,including the spare, frequently, andreplace them if one or more of thefollowing conditions exist:
Tire Wear
When the tread is worn down to onesixteenth of an inch (2 millimeters), tiresmust be replaced to help prevent yourvehicle from skidding and hydroplaning.Built-in treadwear indicators, or wearbars, which look like narrow strips ofsmooth rubber across the tread willappear on the tire when the tread isworn down to one sixteenth of an inch(2 millimeters).
When the tire tread wears down to thesame height as these wear bars, the tireis worn out and must be replaced.
Damage
Periodically inspect the tire treads andsidewalls for damage (such as bulges inthe tread or sidewalls, cracks in the
tread groove and separation in the treador sidewall). If damage is observed orsuspected have the tire inspected by atire professional. Tires can be damagedduring off-road use, so inspection afteroff-road use is also recommended.
Age
WARNING: Tires degrade overtime depending on many factors suchas weather, storage conditions, andconditions of use (load, speed, inflationpressure) the tires experiencethroughout their lives.
WARNING: In general, tires shouldbe replaced after six years regardlessof tread wear or even if they have notbeen used. However, heat caused byhot climates or frequent high-loadconditions can accelerate the agingprocess and may require you to replacetires more frequently.
WARNING: You should replaceyour spare tire when you replace theroad tires or after six years due to agingeven if it has not been used.

U.S. DOT Tire Identification Number
Both U.S. 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 use replacementtires and wheels that are the same size,load index, speed rating and type (suchas P-metric versus LT-metric orall-season versus all-terrain) as thoseoriginally provided by Ford. Therecommended tire and wheel size maybe found on either the SafetyCompliance Certification Label (affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver’sseating position), or the Tire Label whichis located on the B-Pillar or edge of thedriver’s door. If this information is notfound on these labels, then you shouldcontact your authorized dealer as soon
as possible. Use of any tire or wheel notrecommended by Ford can affect thesafety and performance of your vehicle,which could result in an increased riskof loss of vehicle control, vehiclerollover, personal injury and death.
WARNING: To reduce the risk ofserious injury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewall of thetire to set the beads without additionalprecautions listed below. If the beadsdo not seat at the maximum pressureindicated, re-lubricate and try again.
WARNING: When inflating the tirefor mounting pressures up to 20 psi
(1.38 bar) greater than the maximumpressure on the tire sidewall, thefollowing precautions must be taken toprotect the person mounting the tire:
WARNING: 1. Make sure that youhave the correct tire and wheel size.

WARNING: 2. Lubricate the tirebead and wheel bead seat area again.
WARNING: 3. Stand at a minimumof 12 ft (3.66 m) away from the wheeland tire assembly.
WARNING: 4. Use both eye andear protection.
WARNING: For a mountingpressure more than 20 psi (1.38 bar)greater than the maximum pressure, aFord 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 from thewheel and tire assembly.
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.
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 by Ford Motor Companymay affect the operation of your tirepressure 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 bedamaged.
Safety Practices
WARNING: If your vehicle is stuckin snow, mud or sand, do not rapidly spinthe tires; spinning the tires can tear thetire and cause an explosion. A tire canexplode in as little as three to fiveseconds.
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Driving habits have a great deal to dowith your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns
•Avoid potholes and objects on theroad
•Do not run over curbs or hit the tireagainst a curb when parking

Highway Hazards
No matter how carefully you drive thereis always the possibility that you mayeventually have a flat tire on thehighway. Drive slowly to the closest safearea out of traffic. This may furtherdamage the flat tire, but your safety ismore important.
If you feel a sudden vibration or ridedisturbance while driving, or you suspectyour tire or vehicle has been damaged,immediately reduce your speed. Drivewith caution until you can safely pull offthe road. Stop and inspect the tires fordamage. If a tire is under-inflated ordamaged, deflate it, remove the wheeland replace it with your spare tire andwheel (if provided). If you cannot detect
a cause, have the vehicle towed to thenearest repair facility or tire dealer tohave the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or potholecan cause the front end of your vehicleto become misaligned or cause damageto your tires. If your vehicle seems topull to one side when you’re driving, thewheels may be out of alignment. Havean authorized dealer check the wheelalignment periodically.
Wheel misalignment in the front or therear can cause uneven and rapidtreadwear of your tires and should becorrected by an authorized dealer.Front-wheel drive vehicles and thosewith an independent rear suspension (ifequipped) may require alignment of allfour wheels.
The tires should also be balanced
periodically. An unbalanced tire andwheel assembly may result in irregulartire wear.
Tire Rotation
Note:If your tires show uneven wearask an authorized dealer to check forand correct any wheel misalignment,tire imbalance or mechanical probleminvolved before tire rotation.
Note:Your vehicle may be equippedwith a dissimilar spare wheel and tireassembly. A dissimilar spare wheel andtire assembly is defined as a sparewheel and tire assembly that is differentin brand, size or appearance from theroad tires and wheels. If you have adissimilar spare wheel and tire assemblyit is intended for temporary use only andshould not be used in a tire rotation.
Note:After having your tires rotated,inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommendedinterval (as indicated in the ScheduledMaintenance chapter) will help your tireswear more evenly, providing better tireperformance and longer tire life.
