TIRE REPLACEMENT
REQUIREMENTS
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.

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: For a mountingpressure more than 20 psi(1.38 bar) greater than themaximum pressure, a Forddealer or other tire serviceprofessional should do themounting.
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.
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 thetire:
•Make sure that you have thecorrect tire and wheel size.
•Lubricate the tire bead andwheel bead seat area again.
438
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMWheel and Tire Information

•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
If a four tire rotation is beingfollowed, it is recommended thatboth front tires or both rear tiresgenerally be replaced as a pair ifthe two remaining worn tires stillhave usable tread depth. If a fivetire rotation is being followed andthe fifth tire is used to replace asingle unrepairable tire, a four tirerotation should be followed withthe undamaged tires. Any
replacement for the damaged tireshould be used as a dedicatedspare until the remaining tires arereplaced as a set.
To avoid potential Four-WheelDrive (4WD) malfunction or(4WD) system damage, it isrecommended to replace all tiresused in the tire rotation ratherthan mixing significantly worn tireswith new tires.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.
The use of wheels or tires notrecommended may affect theoperation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, yoursystem is malfunctioning. Yourreplacement tire might beincompatible with your tirepressure monitoring system, orsome component of the systemmay be damaged.
USING SNOW CHAINS
WARNING: Do not exceed 30 mph(50 km/h). Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Do not use snow chainson snow-free roads.
WARNING: Only fit snow chains tospecified tires.
WARNING: If your vehicle is fittedwith wheel trims, remove them beforefitting snow chains.
WARNING: If you choose to installsnow tires on your vehicle, they must bethe same size, construction, and loadrange as the original tires listed on thetire placard, and they must be installedon all four wheels. Mixing tires ofdifferent size or construction on yourvehicle can adversely affect yourvehicle's handling and braking, and maylead to loss of vehicle control.
Only use snow chains on rear wheels.Install snow chains in pairs. Do not useself-tensioning snow chains.
Only use snow chains on the followingspecified tire sizes:
439
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMWheel and Tire Information

•255/70R16
•Only install chains that are 15 mmor less.
•255/75R17
•Only install chains that are 15 mmor less.
We recommend you use steel wheels ofthe same size and specification if snowchains are required because chains maychip aluminum wheels.
Follow these guidelines when using snowtires and traction devices:
•If possible, avoid fully loading yourvehicle.
•Purchase snow chains from amanufacturer that clearly labels bodyto tire dimension restrictions.
•When driving with snow chains do notexceed 30 mph (50 km/h) or themaximum speed recommended by thechain manufacturer, whichever is less.
•Drive cautiously. If you hear the snowchains rub or bang against the vehicle,stop and tighten them. If this does notwork, remove the snow chains toprevent vehicle damage.
•Remove the snow chains when theyare no longer needed. Do not use snowchains on dry roads.
•If a temporary spare wheel is mountedon your vehicle, do not use snow chainson the axle with the temporary sparewheel.
Use snow chains that fit against thesidewall of the tire to prevent the chainsfrom touching the wheel rims orsuspension, see following illustrationabove.
If you have any questions regarding snowchains, please contact your authorizeddealer.

CHECKING THE TIRE
PRESSURES
Safe operation of your vehiclerequires that your tires areproperly inflated. Every day beforeyou drive, check your tires.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge. Inflate all tires to therecommended inflation pressure.See Inflating the Tires (page441).
INFLATING THE TIRES
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!
WARNING: Do not use thetire pressure displayed in theinformation display as a tirepressure gauge. Failure to followthis instruction could result inpersonal injury or death.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns.
Inflate your tires to therecommended inflation pressureeven if it is less than the maximuminflation pressure informationfound on the tire. You can find thetire label with the recommendedtire inflation pressure next to thetire size on the B-Pillar or the edgeof the driver door.
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 door.
Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles.

INSPECTING THE TIRE FOR
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.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves.
INSPECTING THE TIRE FOR
DAMAGE
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.
Periodically inspect the tire treadsand sidewalls for damage, suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread or sidewall.If damage is observed orsuspected, have the tire inspectedby a tire professional.
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 as
three to five seconds.
WARNING: Do not spin thewheels at over 34 mph(55 km/h). The tires may fail andinjure a passenger or bystander.

Highway Hazards
No matter how carefully you drive,there is always the possibility thatyou could eventually have a flattire on the highway. Drive slowlyto the closest safe area out oftraffic. This could further damagethe flat tire, but your safety ismore important.
If you feel a sudden vibration orride disturbance while driving, oryou suspect your tire or vehiclehas been damaged, immediatelyreduce your speed. Drive withcaution until you can safely pulloff the road. Stop and inspect thetires for damage. If a tire isunder-inflated or damaged,deflate it, remove the wheel andreplace it with your spare tire andwheel. If you cannot detect acause, have the vehicle towed tothe nearest repair facility or tiredealer to have the vehicleinspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to becomemisaligned or cause damage toyour tires. If your vehicle seems topull to one side when you aredriving, the wheels could be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer.
INSPECTING THE WHEEL
VALVE STEMS
Check the valve stems for holes,cracks, or cuts that could permitair leakage.
TIRE ROTATION
WARNING: If the tire labelshows different tire pressures forthe front and rear tires and thevehicle has a tire pressuremonitoring system, then youneed to update the settings forthe system sensors. Alwaysperform the system resetprocedure after tire rotation. Ifyou do not reset the system, itmay not provide a low tirepressure warning whennecessary.
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to the
vehicle requirements.

2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMTire Care

Rotating your tires at therecommended interval, asindicated in the scheduledmaintenance chapter, will helpyour tires wear more evenly,providing better tire performanceand longer tire life.
For the best tire life, a five tirerotation is recommended thatincludes the matching spare tiremounted on the back of thevehicle. This rotation requires aforced re-learning of your tirepressure monitor system sensorsby your vehicle, and should beperformed by an authorized dealeror a service center to make surethe tire pressure monitoringsystem provides proper warningat all times. When performing thetire rotation yourself, a four tirerotation is recommended, withoutusing the spare tire in the rotation,so that no tire pressure monitorsystem sensor re-learn is required.If a five tire rotation is performedwithout a tire pressure monitorsystem sensor re-learn, thesystem may not provide a low tirepressure warning when necessary.
Keep in mind that a spare tire thatis not used in the tire rotationshould only be used temporarilyin the event of a flat tire, not as apermanent replacement. Thespare tire should always bereplaced if it exceeds 6 years ofage, regardless of whether it ispart of the tire rotation.
Rear-wheel drive vehicles andfour-wheel drive vehicles with fourtire rotation, front tires at left ofdiagram.
Sometimes irregular tire wear canbe corrected by rotating the tires.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
Tire Pressure Monitoring System withIndividual Tire Pressure Display
The tire pressure monitoringsystem measures the vehicle'stire pressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
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. Atire can lose up to half of its air pressureand not appear to be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance CertificationLabel (on the door hinge pillar,door-latch post or the door edge thatmeets the door-latch post, next to thedriver seat) or the Tire Label on theB-Pillar or the edge of the driver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires ofa different size than the size indicated onthe vehicle placard or tire inflation pressurelabel, you should determine the proper tireinflation pressure for those tires).
As an added safety feature, your vehiclehas been equipped with a Tire PressureMonitoring System (TPMS) thatilluminates a low tire pressure telltalewhen one or more of your tires issignificantly under-inflated. Accordingly,when the low tire pressure telltaleilluminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly under-inflated tire causes thetire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiencyand tire tread life, and may affect thevehicle’s handling and stopping ability.
Please note that the TPMS is not asubstitute for proper tire maintenance, andit is the driver’s responsibility to maintaincorrect tire pressure, even if under-inflationhas not reached the level to triggerillumination of the TPMS low tire pressuretelltale.
Your vehicle has also been equipped witha TPMS malfunction indicator to indicatewhen the system is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequencewill continue upon subsequent vehiclestart-ups as long as the malfunction exists.
445
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMTire Pressure Monitoring SystemE139232

When the malfunction indicator isilluminated, the system may not be ableto detect or signal low tire pressure asintended. TPMS malfunctions may occurfor a variety of reasons, including theinstallation of replacement or alternatetires or wheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or more tires orwheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to functionproperly.

TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. Youshould periodically check tire pressuresusing a pressure gauge. Failure tocorrectly maintain tire pressures couldincrease the risk of tire failure, loss ofcontrol, vehicle rollover and personalinjury.
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failureto follow this instruction could result inpersonal injury or death.
Note:The use of tire sealants can damagethe tire pressure monitoring system.
Note:If the tire pressure monitor sensorbecomes damaged it may not function.
TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature dropssignificantly, the tire pressure coulddecrease and activate the low tire pressurewarning lamp.
The warning lamp could also illuminatewhen you use a spare wheel, or tire sealantfrom the inflator kit.
Note:Regularly checking the vehicle tirepressures can reduce the possibility for thewarning lamp to illuminate due to outsideair temperature changes.
Note:After you inflate the tires to therecommended pressure it could take up totwo minutes of driving over 20 mph(32 km/h) for the warning indicator to turnoff.
