2016 FORD F450 SUPER DUTY tire pressure

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.

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.

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.

•To reduce the chances of interferencefrom another vehicle, perform thesystem reset procedure at least threefeet (one meter) away from anotherFord Motor Company vehicleundergoing the system reset procedureat the same time.
•Do not wait more than two minutesbetween resetting each tire sensor orthe system will time-out and the entireprocedure will have to be repeated onall four wheels.
•A double horn will sound indicating theneed to repeat the procedure.
Performing the System Reset Procedure
Read the entire procedure beforeattempting.
1. Drive the vehicle above 20 mph (32km/h) for at least two minutes, thenpark in a safe location where you caneasily get to all four tires and haveaccess to an air pump.
2.Place the ignition in the off position andkeep the key in the ignition.
3. Cycle the ignition to the on positionwith the engine off.
4. Turn the hazard flashers on then offthree times. You must accomplish thiswithin 10 seconds. If the reset modehas been entered successfully, the hornwill sound once, the system indicatorwill flash and a message is shown inthe information display. If this does notoccur, please try again starting at Step2. If after repeated attempts to enterthe reset mode, the horn does notsound, the system indicator does notflash and no message is shown in theinformation display, seek service fromyour authorized dealer.
5. Train the tire pressure monitoringsystem sensors in the tires using thefollowing system reset sequencestarting with the left front tire in thefollowing clockwise order: Left front(driver's side front tire), Right front(passenger's side front tire), Right rear(passenger's side rear tire), Left rear(driver's side rear tire).
6. Remove the valve cap from the valvestem on the left front tire. Decrease theair pressure until the horn sounds.Note: The single horn chirp confirmsthat the sensor identification code hasbeen learned by the module for thisposition. If a double horn is heard, thereset procedure was unsuccessful, andyou must repeat it.
7. Remove the valve cap from the valvestem on the right front tire. Decreasethe air pressure until the horn sounds.
8. Remove the valve cap from the valvestem on the right rear tire. Decrease theair pressure until the horn sounds.
9. Remove the valve cap from the valvestem on the left rear tire. Decrease theair pressure until the horn sounds.Training is complete after the hornsounds for the last tire trained (driver'sside rear tire), the system indicatorstops flashing, and a message is shownin the information display.
10.Turn the ignition off. If two short hornbeeps are heard, the reset procedurewas unsuccessful and you mustrepeat it. If after repeating theprocedure and two short beeps areheard when the ignition is turned tooff, seek assistance from yourauthorized dealer.

CHANGING A ROAD WHEEL
WARNINGS
The use of tire sealant may damageyour tire pressure monitoring systemand should only be used in roadsideemergencies. If you must use a sealant, theFord Tire Mobility Kit sealant should beused. The tire pressure monitoring systemsensor and valve stem on the wheel mustbe replaced by an authorized dealer afteruse of the sealant.
If the tire pressure monitor sensorbecomes damaged, it will no longerfunction. See Tire PressureMonitoring System (page 284).
Note:If your vehicle is equipped with thetire pressure monitoring system, theindicator light will illuminate when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
If you get a flat tire while driving, do notapply the brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safeplace on the side of the road.
If your vehicle is equipped with the tirepressure monitoring system, have a flatserviced by an authorized dealer in orderto prevent damage to the system sensors.See Tire Pressure Monitoring System(page 284). Replace the spare tire with aroad tire as soon as possible. Duringrepairing or replacing of the flat tire, havethe authorized dealer inspect the systemsensor for damage.
Dissimilar Spare Wheel and TireAssembly Information
WARNING
Failure to follow these guidelinescould result in an increased risk ofloss of vehicle control, injury or death.
If you have a dissimilar spare wheel andtire, then it is intended for temporary useonly. This means that if you need to use it,you should replace it as soon as possiblewith a road wheel and tire assembly thatis the same size and type as the road tiresand wheels that were originally providedby Ford. If the dissimilar spare tire or wheelis damaged, it should be replaced ratherthan repaired.
A dissimilar spare wheel and tire assemblyis defined as a spare wheel and tireassembly that is different in brand, size orappearance from the road tires and wheelsand can be one of three types:
1.T-type mini-spare: This spare tirebegins with the letter T for tire size andmay have Temporary Use Only molded inthe sidewall.
2.Full-size dissimilar spare with labelon wheel: This spare tire has a label onthe wheel that states: THIS WHEEL ANDTIRE ASSEMBLY FOR TEMPORARY USEONLY
When driving with one of the dissimilarspare tires listed above, do not:
