Location of the Tire Label
You will find a Tire Labelcontaining tire inflation pressureby tire size and other importantinformation located on the B-Pillaror the edge of the driver's door.See Load Carrying (page 218).
Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, checkyour tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommendedby us.

You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugescould be inaccurate. Werecommend the use of a digital ordial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationcould cause uneven treadwearpatterns.
WARNING: Under-inflationis the most common cause oftire failures and may result insevere tire cracking, treadseparation or blowout, withunexpected loss of vehiclecontrol and increased risk ofinjury. Under-inflation increasessidewall flexing and rollingresistance, resulting in heatbuildup and internal damage tothe tire. It also may result inunnecessary tire stress, irregularwear, loss of vehicle control andaccidents. A tire can lose up tohalf of its air pressure and notappear to be flat!
Always inflate your tires to ourrecommended inflation pressureeven if it is less than the maximuminflation pressure informationfound on the tire. Ourrecommended tire inflation
pressure is found on the SafetyCompliance Certification Label or
Tire Label (affixed to either thedoor hinge pillar, door-latch post,or the door edge that meets thedoor-latch post, next to thedriver's seating position), or TireLabel located on the B-pillar orthe edge of the driver's door.Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles.
Note:Do not reduce tire pressureto change the ride characteristicsof the vehicle. If you do notmaintain the inflation pressure atthe levels specified by us, yourvehicle could experience acondition known as shimmy.Shimmy is a severe vibration andoscillation in the steering wheelafter the vehicle travels over abump or dip in the road that doesnot dampen out by itself. Shimmycould result from significantunder-inflation of the tires,improper tires (load range, size, ortype), or vehicle modifications suchas lift-kits. In the event that yourvehicle experiences shimmy, youshould slowly reduce speed byeither lifting off the acceleratorpedal or lightly applying the brakes.The shimmy will cease as thevehicle speed decreases.
Maximum Inflation Pressure isthe tire manufacturer's maximumpermissible pressure and thepressure at which the maximum
load can be carried by the tire. Thispressure is normally higher than

Note:Some spare tires operate ata higher inflation pressure than theother tires. For T type mini-sparetires, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat 60 psi (4.15 bar). For full-sizeand dissimilar spare tires, see theDissimilar spare wheel and tireassembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6. Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tire andcause an air leak.
7. Check the sidewalls to makesure there are no gouges, cuts orbulges.
Inspecting Your Tires andWheel Valve Stems
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that could bewedged in the tread grooves.Check the tire and valve stems forholes, cracks, or cuts that couldpermit air leakage and repair orreplace the tire and replace thevalve stem. Inspect the tiresidewalls for cracking, cuts,bruises and other signs of damageor excessive wear. If internaldamage to the tire is suspected,have the tire dismounted and
inspected in case it needs to berepaired or replaced. For yoursafety, tires that are damaged orshow signs of excessive wearshould not be used because theyare more likely to blow out or fail.
Improper or inadequate vehiclemaintenance can cause tires towear abnormally. Inspect all yourtires, including the spare,frequently, and replace them ifone or more of the followingconditions exist:
Tire Wear
When the tread is worn down toone sixteenth of an inch (2millimeters), tires must bereplaced to help prevent yourvehicle from skidding andhydroplaning. Built-in treadwearindicators, or wear bars, whichlook like narrow strips of smoothrubber across the tread willappear on the tire when the treadis worn down to one sixteenth ofan inch (2 millimeters).

2023 Ranger (TFG) Canada/United States of America, Vehicles Built From: 10-10-2022, enUSA, Edition date: 202208, First-PrintingWheels and TiresE142546

When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.
Damage
Periodically inspect the tire treadsand sidewalls for damage (suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread orsidewall). If damage is observedor suspected have the tireinspected by a tire professional.Tires can be damaged duringoff-road use, so inspection afteroff-road use is alsorecommended.
Age
WARNING: Tires degradeover time depending on manyfactors such as weather, storageconditions, and conditions of use(load, speed, inflation pressure)the tires experience throughouttheir lives.
WARNING: In general, tiresshould be replaced after sixyears regardless of tread wear.However, heat caused by hotclimates or frequent high loadingconditions can accelerate theaging process and may requiretires to be replaced morefrequently.
WARNING: You shouldreplace your spare tire when youreplace the road tires or after sixyears due to aging even if it hasnot been used.
U.S. DOT Tire IdentificationNumber
Both United States and CanadaFederal regulations require tiremanufacturers to placestandardized information on thesidewall of all tires. Thisinformation identifies anddescribes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT TireIdentification Number for safetystandard certification and in case
of a recall.
This begins with the letters DOTand indicates that the tire meetsall federal standards. The nexttwo numbers or letters are theplant code designating where itwas manufactured, the next twoare the tire size code and the lastfour numbers represent the weekand year the tire was built. Forexample, the numbers 317 meanthe 31st week of 1997. After 2000the numbers go to four digits. Forexample, 2501 means the 25thweek of 2001. The numbers inbetween are identification codesused for traceability. Thisinformation is used to contactcustomers if a tire defect requiresa recall.

Tire ReplacementRequirements
Your vehicle is equipped with tiresdesigned to provide a safe rideand handling capability.
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: 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 the
tire:
•Make sure that you have thecorrect tire and wheel size.
•Lubricate the tire bead andwheel bead seat area again.
•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
WARNING: For a mountingpressure more than 20 psi(1.38 bar) greater than themaximum pressure, a Forddealer or other tire serviceprofessional should do the
mounting.

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.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
The two front tires or two rear tiresshould generally be replaced as apair, except if the vehicle isequipped with four wheel drive.Vehicles equipped with four wheeldrive should have all four tiresreplaced simultaneously.Unevenly worn tires, mismatchedmakes, models or brands can bedifferent in size, resulting inpotential damage to the fourwheel drive system.
The tire pressure sensors mountedin the wheels are not designed tobe used in aftermarket wheels.
The use of wheels or tires notrecommended by us could affectthe operation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, thesystem is malfunctioning. Yourreplacement tire might beincompatible with your tirepressure monitoring system, orsome component of the system
could be damaged.
Safety Practices
WARNING: If your vehicleis stuck in snow, mud or sand, donot rapidly spin the tires;spinning the tires can tear thetire and cause an explosion. Atire can explode in as little asthree to five seconds.
WARNING: Do not spin thewheels at over 34 mph(55 km/h). The tires may fail andinjure a passenger or bystander.
Driving habits have a great dealto do with your tire mileage andsafety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects onthe road
*Do not run over curbs or hit thetire against a curb when parking
Highway Hazards
No matter how carefully you drivethere is always the possibility thatyou could eventually have a flattire on the highway. Drive slowly
to the closest safe area out oftraffic. This could further damagethe flat tire, but your safety ismore important.
