the material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which allpassenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing the originalequipment tire sizes, recommendedinflation pressure and the maximumweight the vehicle can carry.
*Tire Identification Number (TIN): A
number on the sidewall of each tireproviding information about the tirebrand and manufacturing plant, tire sizeand date of manufacture. Also referredto 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 will notincrease the tire’s load carryingcapability.
*Extra load: A class of P-metric or Metrictires designed to carry a heaviermaximum load at 42 psi (2.9 bar).Increasing the inflation pressure beyondthis pressure will not increase the tire’sload carrying capability.
*kPa: Kilopascal, a metric unit of airpressure.
*PSI: Pounds per square inch, a standard
unit of air pressure.
*Cold tire pressure: The tire pressurewhen the vehicle has been stationaryand out of direct sunlight for an hour ormore and prior to the vehicle beingdriven for 1 mi (1.6 km).
*Recommended inflation pressure: Thecold inflation pressure found on 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), or Tire Labellocated on the B-Pillar or the edge of thedriver door.
* B-pillar: The structural member at theside of the vehicle behind the front door.
*Bead area of the tire: Area of the tirenext to the rim.
* Sidewall of the tire: Area between thebead area and the tread.
*Tread area of the tire: Area of theperimeter of the tire that contacts the
road when mounted on the vehicle.
*Rim: The metal support (wheel) for atire or a tire and tube assembly uponwhich the tire beads are seated.

Recommended Tire Pressures andInflating 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 the pressureof all tires 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.
WARNING: Under-inflation is themost common cause of tire failuresand may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rolling
resistance, resulting in heat buildup

and internal damage to the tire. It alsomay result in unnecessary tire stress,irregular wear, loss of vehicle controland accidents. A tire can lose up tohalf of its air pressure and not appearto be flat!
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 recommendedcold inflation pressure for optimum tireperformance and wear. Under-inflationor over-inflation may cause uneventreadwear patterns.
Always inflate your tires to the Fordrecommended inflation pressure evenif it is less than the maximum inflationpressure information found on the tire.You will find a Tire Label containing theFord recommended tire inflationpressure by the tire size and otherimportant information located on theB-Pillar or the edge of the driver’s door.
The Ford recommended tire inflationpressure is also found on the SafetyCompliance Certification Label (affixedto either the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch on the B-pillar, or on the edgeof the driver’s door.
Failure to follow the tire pressurerecommendations can cause uneventreadwear patterns and adversely affectthe way your vehicle handles.
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 tread
grooves. 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 is
suspected, 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
323
MKT (TP4) , enUSA, Edition date: 201803, Second-Printing
Wheels and TiresE142546

When the tread is worn down to onesixteenth of an inch (2 mm), tires mustbe replaced to help prevent your vehiclefrom skidding and hydroplaning. Built-intreadwear indicators, or wear bars,which look like narrow strips of smoothrubber across the tread will appear onthe tire when the tread is worn down toone sixteenth of an inch (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.In general, tires should be replacedafter six years regardless of treadwear. However, heat caused by hotclimates or frequent high loadingconditions can accelerate the agingprocess and may require tires to bereplaced more frequently.You should replace your spare tirewhen you replace the road tires orafter six years due to aging even if ithas not been 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.
WARNING: Only use replacementtires and wheels that are the samesize, load index, speed rating and type(such as 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-latch post, or the door edge thatmeets the door-latch post, next to thedriver's seating position), or the TireLabel which is located on the B-Pillaror edge of the driver's door. If thisinformation is not found on theselabels, then you should contact yourauthorized dealer as soon as possible.Use of any tire or wheel not
recommended by Ford can affect thesafety and performance of yourvehicle, which could result in anincreased risk of loss of vehiclecontrol, vehicle rollover, personalinjury and death.
WARNING: To reduce the risk ofserious injury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewall ofthe tire to set the beads withoutadditional precautions listed below. Ifthe beads do not seat at the maximumpressure indicated, re-lubricate andtry again.
WARNING: For a mounting
pressure more than 20 psi (1.38 bar)greater than the maximum pressure,a Ford 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 fromthe wheel and tire assembly.
WARNING: When inflating thetire for mounting pressures up to20 psi (1.38 bar) greater than themaximum pressure on the tire sidewall,the following precautions must betaken to protect the person mountingthe tire:
•Make sure that you have the correcttire and wheel size.
•Lubricate the tire bead and wheelbead seat area again.
•Stand at a minimum of 12 ft (3.66 m)away from the wheel and tireassembly.
•Use both eye and ear protection.
Important: Remember to replace thewheel valve stems when the road tiresare replaced on your vehicle.
