2016 FORD F450 SUPER DUTY flat tire

WARNINGS
When inflating the tire formounting pressures up to 20 psi(1.38 bar) greater than themaximum pressure on the tiresidewall, the followingprecautions must be taken toprotect the person mounting thetire:
1. Make sure that you have thecorrect tire and wheel size.
2. Lubricate the tire bead andwheel bead seat area again.
3. Stand at a minimum of 12 ft(3.6 m) away from the wheel andtire assembly.
4. Use both eye and earprotection.
For a mounting pressure morethan 20 psi (1.38 bar) greater thanthe maximum pressure, a Forddealer or other tire serviceprofessional should do themounting.
Always inflate steel carcass tireswith a remote air fill with theperson inflating standing at aminimum of 12 ft (3.6 m) awayfrom the wheel and tire assembly.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on your
vehicle.
The two front tires or two rear tiresshould generally be replaced as apair.
The tire pressure sensors mountedin the wheels are not designed tobe used in aftermarket wheels.
The use of wheels or tires notrecommended by Ford MotorCompany may affect theoperation 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 systemmay be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck insnow, mud, or sand, do notrapidly spin the tires; spinning thetires can tear the tire and causean explosion. A tire can explode inas little as three to five seconds.
Do not spin the wheels atover 35 mph (56 km/h). Thetires may fail and injure apassenger or bystander.
Driving habits have a great dealto do with your tire mileage andsafety.
*Observe posted speed limits.

*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 theclosest 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, immediately
reduce 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 becomemisaligned 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 mayrequire alignment of all fourwheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
WARNING
If the tire label showsdifferent tire pressures for thefront and rear tires and the vehicleis equipped with a tire pressuremonitoring system, then thesettings for the system sensorsneed to be updated. Alwaysperform the system resetprocedure after tire rotation. If thesystem is not reset, it may notprovide a low tire pressurewarning when necessary.

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. Sometimeirregular tire wear can becorrected by rotating the tires.

If your vehicle is equipped withdual rear wheels it isrecommended that the front andrear tires (in pairs) be rotated onlyside to side. We do notrecommend splitting up the dualrear wheels. Rotate them side toside as a set. After tire rotation,inflation pressures must beadjusted for the tires newpositions in accordance withvehicle requirements.
USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index, speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath. Additionally, the use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure.
Note:Do not use snow chains on vehicleswith 20 inch wheels and tires.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you needto use cables, it is recommended that steelwheels (of the same size andspecifications) be used, as cables may chipaluminum wheels.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle
•Use only SAE Class S chains.
•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking the tire pressure. The tirepressure should be checked periodically(at least monthly) using a tire pressuregauge. Failure to properly maintain yourtire pressure could increase the risk of tirefailure, loss of control, vehicle rollover andpersonal injury.
284

Wheels and Tires

Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure 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.
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.
The tire pressure monitoring systemcomplies with part 15 of the FCC rules andwith RSS-210 of Industry Canada.Operation is subject to the following twoconditions: (1) This device may not causeharmful interference, and (2) This devicemust accept any interference received,including interference that may causeundesired operation.

Changing Tires With a TirePressure Monitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire and isnot visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (atleast monthly) using an accurate tiregauge. See Inflating Your Tires in thischapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your four road tiresand sends the tire pressure readings toyour vehicle. The low tire pressure warninglight will turn on if the tire pressure issignificantly low. Once the light isilluminated, your tires are under-inflatedand need to be inflated to themanufacturer’s recommended tirepressure. Even if the light turns on and ashort time later turns off, your tire pressurestill needs to be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.
When You Believe Your System is NotOperating Properly
The main function of the tire pressuremonitoring system is to warn you whenyour tires need air. It can also warn you inthe event the system is no longer capableof functioning as intended. See thefollowing chart for information concerningyour tire pressure monitoring system:

When Inflating Your Tires
When putting air into your tires (such as ata gas station or in your garage), the tirepressure monitoring system may notrespond immediately to the air added toyour tires.
It may take up to two minutes of drivingover 20 mph (32 km/h) for the light to turnoff after you have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. While driving in a normal manner, atypical passenger tire inflation pressuremay increase about 2 to 4 psi (14 to 28kPa) from a cold start situation. If thevehicle is stationary overnight with theoutside temperature significantly lowerthan the daytime temperature, the tirepressure may decrease about 3 psi (21kPa) for a drop of 30°F (17°C) in ambienttemperature. This lower pressure valuemay be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflationpressure and activate the system warninglight for low tire pressure.
If the low tire pressure warning light is on,visually check each tire to verify that no tireis flat. If one or more tires are flat, repair asnecessary. Check the air pressure in theroad tires. If any tire is under-inflated,carefully drive the vehicle to the nearestlocation where air can be added to thetires. Inflate all the tires to therecommended inflation pressure.
Tire Pressure Monitoring System ResetProcedure
WARNING
To determine the requiredpressure(s) for your vehicle, see theSafety Compliance CertificationLabel (affixed to either the door hingepillar, door-latch post, or the door edgethat meets the door-latch post, next to thedriver's seating position), or Tire Labellocated on the B-Pillar or the edge of thedriver's door.
Note:You need to perform the tire pressuremonitoring system reset procedure aftereach tire rotation on vehicles that requiredifferent recommended tire pressures in thefront tires as compared to the rear tires.
Overview
To provide the vehicle's load carryingcapability, some vehicles require differentrecommended tire pressures in the fronttires as compared to the rear tires. The tirepressure monitoring system equipped onthese vehicles is designed to illuminate thelow tire pressure warning light at twodifferent pressures; one for the front tiresand one for the rear tires.
Since tires need to be rotated to provideconsistent performance and maximum tirelife, the tire pressure monitoring systemneeds to know when the tires are rotatedto determine which set of tires are on thefront and which are on the rear. With thisinformation, the system can detect andproperly warn of low tire pressures.
