K. Maximum Load: Indicates themaximum load in kilograms and poundsthat can be carried by the tire. See theSafety Compliance Certification Label(affixed to either the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver's seating position), for the correcttire pressure for your vehicle.
L. Treadwear, Traction andTemperature Grades:
*Treadwear The treadwear grade is acomparative rating based on the wearrate of the tire when tested undercontrolled conditions on a specifiedgovernment test course. For example,a tire graded 150 would wear one andone-half times as well on the
government course as a tire graded 100.
*Traction: The traction grades, fromhighest to lowest are AA, A, B, and C.The grades represent the tire's ability tostop on wet pavement as measuredunder controlled conditions on specifiedgovernment test surfaces of asphalt andconcrete. A tire marked C may havepoor traction performance.
*Temperature: The temperature gradesare A (the highest), B and C,representing the tire's resistance to thegeneration of heat and its ability todissipate heat when tested undercontrolled conditions on a specifiedindoor laboratory test wheel.
M. Maximum Inflation Pressure:Indicates the tire manufacturer'smaximum permissible pressure, or the
pressure 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 to
the 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 additionalmarkings, 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 tirepressure 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 the most commoncause of tire failures and may resultin severe tire cracking, tread separationor blowout, with unexpected loss ofvehicle control and increased risk of
injury. Under-inflation increases sidewallflexing and rolling resistance, resultingin heat buildup and internal damage tothe tire. It also may result in unnecessarytire stress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!

Wheels and Tires

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, meaningthey are not hot from driving even amile.
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 tire gaugeonto the valve and measure thepressure.
3. Add enough air to reach therecommended air pressure.

Wheels and Tires

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 section. Store and maintainat 60 psi (4.15 bar). For full-size anddissimilar spare tires, see the DissimilarSpare Wheel and Tire AssemblyInformation section. Store and maintainat the higher of the front and rearinflation pressure as shown on the Tire
Label.
6. Visually inspect the tires to make surethere are no nails or other objectsembedded that could poke a hole in thetire and cause an air leak.
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 thatare 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 tire
is 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 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 over time dependingon many factors such as weather,storage conditions, and conditions ofuse (load, speed, inflation pressure) thetires experience throughout their lives.
You should replace your spare tire whenyou replace the road tires or after sixyears due to aging even if it has notbeen 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.
WARNINGS
Only use replacement tires andwheels that are the same size, loadindex, speed rating and type (such asP-metric versus LT-metric or all-seasonversus all-terrain) as those originallyprovided by Ford. The recommendedtire and wheel size may be found oneither the Safety ComplianceCertification Label (affixed to either thedoor hinge pillar, door-latch post, or thedoor edge that meets the door-latchpost, next to the driver's seatingposition), or the Tire Label which is
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

WARNINGS
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.
To reduce the risk of serious injury,when mounting replacement tiresand wheels, you should not exceed themaximum pressure indicated on thesidewall of the tire to set the beadswithout additional precautions listedbelow. If the beads do not seat at themaximum pressure indicated,re-lubricate and try again.
When inflating the tire for mountingpressures up to 20 psi (136 kPa)
greater than the maximum pressure onthe tire sidewall, the followingprecautions must be taken to protectthe person mounting the tire:
1. Make sure that you have the correcttire and wheel size.
WARNINGS
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 tire assembly.
4. Use both eye and ear protection.
For a mounting pressure more than20 psi (1.38 bar) greater than themaximum pressure, a Ford dealer orother tire service professional should dothe mounting.
Always inflate steel carcass tires with aremote air fill with the person inflatingstanding at a minimum of 12 ft (3.66 m)away from the wheel and tire assembly.
Important: Remember to replace thewheel valve stems when the road tiresare replaced on your vehicle.
The two front tires or two rear tiresshould generally be replaced 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, the system ismalfunctioning. Your replacement tiremight be incompatible with your tirepressure monitoring system, or somecomponent of the system may bedamaged.
Safety Practices
WARNINGS
If your vehicle is stuck in 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.
