![FORD SUPER DUTY 2023 Owners Manual 1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
Note:If you are checking tirepressure when the tire is hot, (forexample, driven more than 1 mile[1.6 kilometers]), nev FORD SUPER DUTY 2023 Owners Manual 1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
Note:If you are checking tirepressure when the tire is hot, (forexample, driven more than 1 mile[1.6 kilometers]), nev](/manual-img/11/58820/w960_58820-494.png)
1. Make sure the tires are cool,meaning they are not hot fromdriving even a mile.
Note:If you are checking tirepressure when the tire is hot, (forexample, driven more than 1 mile[1.6 kilometers]), never bleed orreduce air pressure. The tires arehot from driving and it is normal forpressures to increase aboverecommended cold pressures. Ahot tire at or below recommendedcold inflation pressure could besignificantly under-inflated.
2. Remove the cap from the valveon one tire, then firmly press thetire gauge onto the valve andmeasure the pressure.
3. Add enough air to reach therecommended air pressure.
Note:If you overfill the tire, releaseair by pressing on the metal stemin the center of the valve. Thenrecheck the pressure with your tiregauge.
4. Replace the valve cap.
5. Repeat this procedure for eachtire, including the spare.
Note:Some spare tires operate ata higher inflation pressure than theother tires. For T type mini-sparetires, (see the Dissimilar sparewheel and tire assemblyinformation for a description. Storeand maintain at 60 psi(4.15 bar)60 psi (4.15 bar). Forfull-size and dissimilar spare tires,see the Dissimilar spare wheel andtire assembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
Note:Do not reduce tire pressureto change the ride characteristicsof the vehicle. If you do notmaintain the inflation pressure atthe levels specified by Ford, yourvehicle may experience a conditionknown as shimmy. Shimmy is asevere vibration and oscillation inthe steering wheel after the vehicletravels over a bump or dip in theroad that does not dampen out byitself. Shimmy may result fromsignificant under-inflation of thetires, improper tires (load range,size, or type), or vehiclemodifications such as lift-kits. Inthe event that your vehicleexperiences shimmy, you shouldslowly reduce speed by either liftingoff the accelerator pedal or lightlyapplying the brakes. The shimmywill cease as the vehicle speeddecreases.

CHANGING A FLAT TIRE
If you get a flat tire when 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.
Have a flat serviced by an authorizeddealer to prevent damage to the systemsensors. See Tire Pressure MonitoringSystem Precautions (page 502).Replacethe spare tire with a road tire as soon aspossible. During repairing or replacing theflat tire, have the authorized dealer inspectthe system sensor for damage.
Note:The use of tire sealant may damageyour tire pressure monitoring system andshould only be used in roadsideemergencies.
Note:The tire pressure monitoring systemindicator light illuminates 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 this vehicle.
Dissimilar Spare Wheel and TireAssembly Information
WARNING: Failure to follow theseguidelines could result in an increasedrisk of loss of vehicle control, injury ordeath.
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.

•Use snow chains on the end of thevehicle with the dissimilar spare wheeland tire assembly.
•Engage any four-wheel drive mode.See Four-Wheel Drive Limitations(page 239).
When driving with the full-size dissimilarspare wheel and tire assembly, 4WDfunctionality may be limited. You mayexperience the following:
•Additional noise from the transfer caseor other drive components.
•Difficulty shifting out of a mechanicallylocked 4WD mode.
When driving with the full-size dissimilarspare wheel and tire assembly, it isrecommended that you do not:
•Engage 4WD High or 4WD Low, ifequipped, other than to get your vehicleunstuck. .
The usage of a full-size dissimilar sparewheel and tire assembly can lead toimpairment of the following:
