GENERAL INFORMATION
The recommended tire inflation pressuresare found on the Tire Label which islocated on the B-pillar or the edge of thedriver door. This information can also befound on the Safety ComplianceCertification Label, affixed to either thedoor hinge pillar, door-latch post, or thedoor edge that meets the door-latch post,next to the driver’s seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect theway your vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at leastonce per month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Use only approved wheels and tire sizes;using other sizes could damage yourvehicle.
If you change the diameter of the factoryinstalled tires, the speedometer coulddisplay the incorrect speed. This couldeffect the functionality of the 4WD system(if equipped). Take your vehicle to anauthorized dealer and have the enginemanagement system reprogrammed.
If you intend to change the size of thefactory installed tires, check the suitabilitywith an authorized dealer.
Additional information related to thefunctionality and maintenance of your tirescan be found in the Wheels and Tiresection. See Tire Care (page 349).
Self-Sealing Tires (If Equipped)
Self-Sealing tires are a special type of tirethat have a material on the inside of thetire that can seal punctures up to 0.2 in(6 mm) in diameter in the tread area. Thismaterial does not protect from damage orpunctures in the sidewall of the tire.Self-sealing tires can be identified by thetire manufacturer with a special mark.
If your TPMS warning light comes on,inspect your tires for damage and re-inflateyour tires to the pressure indicated on thetire placard. See Tire PressureMonitoring System (page 364). If yourtires are damaged or continue to lose air,take your vehicle to the nearest authorizeddealer to have your tires inspected andrepaired/replaced as necessary.
Note:Replace self-sealing tires withself-sealing tires to maintain thefunctionality provided.
Note:Do not drive on a deflatedself-sealing tire. This damages the tirebeyond repair.
Notice to utility vehicle and truckowners
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly morelikely to die than a person wearing aseatbelt.

The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING: Thetemperature grade for this tire isestablished for a tire that isproperly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlled conditionson a specified indoor laboratorytest wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under the
Federal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) andfor Metric tires 36 psi (2.5 bar).Increasing the inflation pressurebeyond this pressure will notincrease the tire’s load carryingcapability.

Recommended Tire Pressuresand 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 the 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 the manufacturer.
WARNING: Under-inflationis the most common cause oftire failures and may result insevere tire cracking, treadseparation or blowout, withunexpected loss of vehicle
control 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!
You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Werecommend the use of a digital ordial-type tire pressure gaugerather than a stick-type tirepressure gauge. Use therecommended cold inflationpressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns.
Always inflate your tires to therecommended inflation pressureeven if it is less than the maximuminflation pressure informationfound on the tire. You will find aTire Label containing themanufactures recommended tireinflation pressure by the tire sizeand other important informationlocated on the B-Pillar or the edgeof the driver’s door).
356
2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingWheels and Tires

The recommended tire inflationpressure is also found on theSafety Compliance CertificationLabel (affixed to either the doorhinge pillar, door-latch post, or thedoor edge that meets thedoor-latch on the B-pillar, or onthe edge of the driver’s door.
Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles.
Inspecting Your Tires andWheel Valve Stems
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedged
in the tread grooves. Check the tireand valve stems for holes, cracks,or cuts that may permit airleakage and repair or replace thetire and replace the valve stem.Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredismounted and inspected in caseit needs to be repaired or replaced.For your safety, tires that aredamaged or show signs ofexcessive wear should not be usedbecause they are more likely toblow 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 (2 mm),tires must be replaced to helpprevent your vehicle from skiddingand hydroplaning. Built-intreadwear indicators, or wear bars,which look like narrow strips ofsmooth rubber across the treadwill appear on the tire when thetread is worn down to onesixteenth of an inch (2 mm).
When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.

2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingWheels and TiresE142546

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.In general, tires should bereplaced after six yearsregardless of tread wear.However, heat caused by hotclimates or frequent high loadingconditions can accelerate theaging process and may requiretires to be replaced morefrequently.
You should replace your sparetire when you replace the roadtires or after six years due toaging even if it has not beenused.
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 caseof 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 2000,the 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.
