•Treadwear The treadwear grade isa comparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150 wouldwear one and one-half times as wellon the government course as a tiregraded 100.
•Traction: The traction grades, fromhighest to lowest are AA, A, B, andC. The grades represent the tire'sability to stop on wet pavement asmeasured under controlledconditions on specified governmenttest surfaces of asphalt and concrete.A tire marked C may have poortraction performance.
•Temperature: The temperaturegrades are A (the highest), B and C,representing the tire's resistance tothe generation of heat and its abilityto dissipate heat when tested undercontrolled conditions on a specifiedindoor laboratory test wheel.
M. Maximum Inflation Pressure:Indicates the tire manufacturers'maximum permissible pressure or thepressure at which the maximum loadcan be carried by the tire. This pressureis normally higher than the vehiclemanufacturer's recommended coldinflation pressure which can be foundon the Safety Compliance CertificationLabel (affixed to either the door hingepillar, door-latch post, or the door edgethat 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 vehicle label.
The tire suppliers may have additional
markings, notes or warnings such asstandard load or radial tubeless.

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(0.07 bar) in inflation pressure. Checkyour tire 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.
Note:If you are checking tire pressurewhen the tire is hot, (for example drivenmore than 1.0 mi (1.6 km), never bleedor reduce air pressure. The tires are hotfrom 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 0.08 in(2 mm), tires must be replaced to helpprevent your vehicle from skidding andhydroplaning. Built-in treadwearindicators, or wear bars, which look likenarrow strips of smooth rubber acrossthe tread will appear on the tire whenthe tread is worn down to 0.08 in(2 mm).
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 thetread groove and separation in the tread
or 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. However, heat caused byhot climates or frequent high loadingconditions can accelerate the agingprocess and may require tires to bereplaced more frequently.You should replace your spare tire whenyou replace the road tires or after six
years due to aging even if it has notbeen 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: Replace the wheelsand tires with the exact original brand,size and construction that cameoriginally on your vehicle. Use of anyother wheel or tire combinations, evenwith identical size ratings, may result ininsufficient running clearances, tirerubbing and eventual puncture. Failureto follow tire replacementrecommendations can lead to tire failure,loss of vehicle control, serious injury ordeath.

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:
1.Make sure that you have the correcttire and wheel size.
2.Lubricate the tire bead and wheelbead seat area again.
3. Stand at a minimum of 12 ft (3.66 m)away from the wheel and tireassembly.
4. Use both eye and ear 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 or
damaged, deflate it, remove the wheeland replace it with your spare tire andwheel (if provided). If you cannot detecta 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 rapid
treadwear 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 balancedperiodically. 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 a
dissimilar 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 andadjusted 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.
Front-wheel drive and all-wheel drivevehicles (front tires on the left side ofthe diagram)
All vehicles with directional tires (fronttires on the left of the diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SUMMER TIRES
Summer tires provide superior performanceon wet and dry roads. Summer tires do nothave the Mud and Snow (M+S or M/S) tiretraction rating on the tire side wall. Sincesummer tires do not have the same tractionperformance as All-season or Snow tires, wedo not recommend using summer tires whentemperatures drop to approximately 45°F(7°C) or below (depending on tire wear andenvironmental conditions) or in snow and ice
conditions. Like any tire, summer tireperformance is affected by tire wear andenvironmental conditions. If you must drivein those conditions, we recommend usingMud and Snow (M+S, M/S), All-season orSnow tires.
Always store your summer tires indoors attemperatures above 19°F (-7°C). The rubbercompounds used in these tires lose flexibilityand may develop surface cracks in the treadarea at temperatures below 19°F (-7°C). If thetires have been subjected to 19°F (-7°C) orless, warm them in a heated space to at least41°F (5°C) for at least 24 hours beforeinstalling them on a vehicle, or moving thevehicle with the tires installed, or checkingtire inflation. Do not place tires near heatersor heating devices used to warm the roomwhere the tires are stored. Do not apply heator blow heated air directly on the tires.Always inspect the tires after storage periodsand before use.
