2023 FORD MUSTANG Owners Manual

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 wedgedin 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 tiredemounted 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.
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 observed

or 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 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 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: 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.
319
2023 Mustang (CZG) Canada/United States of America, Vehicles Built From: 14-11-2022, enUSA, Edition date: 202209, First-PrintingWheels and Tires

•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.
It is recommended that the twofront tires or two rear tiresgenerally be replaced as a pair.
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 by Ford MotorCompany may affect the
operation 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.
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’s always the possibility thatyou may eventually have a flat tireon the highway. Drive slowly to the
closest safe area out of traffic.This may further damage the flattire, but your safety is moreimportant.

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 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 become
misaligned or cause damage toyour tires. If your vehicle seems topull to one side when you’redriving, the wheels may 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. Front-wheeldrive vehicles and those with anindependent rear suspension (ifequipped) may require alignmentof all four wheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to thevehicle requirements.
Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) will helpyour tires wear more evenly,providing better tire performanceand longer tire life. Sometimesirregular tire wear can becorrected by rotating the tires.

USING SUMMER TIRES
Summer tires provide superiorperformance on wet and dry roads.Summer tires do not have the Mud andSnow (M+S or M/S) tire traction rating onthe tire sidewall. Since summer tires do nothave the same traction performance asAll-season or Snow tires, we do notrecommend using summer tires whentemperatures drop to about 45°F (7°C) orbelow (depending on tire wear andenvironmental conditions) or in snow and
ice conditions. Like any tire, summer tireperformance is affected by tire wear andenvironmental conditions. If you must drivein those conditions, we recommend usingMud and Snow (M+S, M/S), All-season orSnow tires.
Always store your summer tires indoors attemperatures above 19°F (-7°C). Therubber compounds used in these tires loseflexibility and may develop surface cracksin the tread area at temperatures below19°F (-7°C). If the tires have beensubjected to 19°F (-7°C) or less, warmthem in a heated space to at least 41°F(5°C) for at least 24 hours before installingthem on a vehicle, or moving the vehiclewith the tires installed, or checking tireinflation. Do not place tires near heatersor heating devices used to warm the roomwhere the tires are stored. Do not applyheat or blow heated air directly on the tires.Always inspect the tires after storageperiods and before use.
Mach 1 Handling Package (If Equipped)
Wheels
Your vehicle has unique wheels matchedto the tires. These wheels are moresusceptible to damage due to theirdiameter, width, and low profile tires.
To avoid damage to your wheels:
•Maintain proper tire pressure
•When installing wheels, always torquelug nuts to specification with a torquewrench.
•Inspect your wheels for damage on aregular basis. If a wheel is damaged,replace it immediately.
•In the event that you encounter aabnormally harsh impact, inspect theouter diameter of your wheels, bothinside and out, for damage.

Tires
Your vehicle has low profile, highperformance tires that are designed tooptimize the driving dynamics you expectin a Ford vehicle. These tires are notoptimized for off-road or winter (snow or
cold weather) performance, and their ride,noise and wear characteristics are differentthan non-performance tires. Also, becauseof their lower profile, the tires are moresusceptible to damage due to potholesand rough roads.

To make sure that your tires perform asintended, it is important that you properlymaintain your tires:
•Your original equipment tires areoptimized for performance in both wetand dry conditions. We do notrecommend using the originalequipment tires when temperaturesdrop to about 45°F (7°C) or below(depending on tire wear andenvironmental conditions) or in snowand ice conditions.
•The tires were designed for track useand may exhibit significantly reducedtread life and increased tire noisecompared to the standard equipmenttires under normal driving conditions.Increasing the front camber settingsbeyond the factory settings may furtheraccelerate tread wear and induce tirenoise.
•For tire pressures, see the placardlocated on the B-pillar inside the driverdoor.
•Always maintain your tire pressuresaccording to the tire informationplacard on the driver door jamb, usingan accurate gauge.
•Tire pressures are specified cold andshould be checked after the vehicle hasbeen parked for at least three hours.Do not reduce the pressure of warmtires.
•Check your tire pressure often tomaintain it properly. Tire pressure candiminish over time and fluctuate withtemperature.
•Do not overload your vehicle.Maximum vehicle and axle weights arelisted on the tire information placard.
•Extra caution should be taken whenoperating the vehicle near its maximumload, including assuring proper tirepressure and reducing speeds.
•Extra caution should be taken whenoperating on rough roads to avoidimpacts that could cause tire damage.
•In the event that you encounter anabnormally harsh impact, inspect yourtires for damage.
•Inspect your tires for damage on aregular basis. If a tire is damaged,immediately replace it.
•Proper suspension alignment is criticalfor maximum performance andoptimal tire wear. If you notice uneventire wear, have your alignment checked.
•Rotate tires as recommended in thetire rotation information. See Tire Care,in the Wheels and Tires Chapter of theOwner's Manual.
•Follow the rotation pattern for"Vehicles equipped with different sizetires on the front and rear axle".
•When replacing tires, the only way tomaintain original performance is to usethe original equipment tire. If a differenttire is used, it should be the same size,speed rating and load rating and bereplaced as a set of four. Never mix tirebrands.
