E.16: Indicates the wheel or rimdiameter in inches. If you changeyour wheel size, you have topurchase new tires to match thenew wheel diameter.
Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommendedby Ford Motor Company.
You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Fordrecommends the use of a digitalor dial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns
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!
Always inflate your tires to theFord recommended inflationpressure even if it is less than themaximum inflation pressureinformation found on the tire. TheFord recommended tire inflationpressure is found on the SafetyCompliance Certification Label orTire Label. Failure to follow the tirepressure recommendations cancause uneven treadwear patternsand adversely affect the way yourvehicle handles.

Maximum Inflation Pressure isthe tire manufacturer's maximumpermissible pressure and thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe manufacturer’s recommendedcold inflation pressure which canbe found on the SafetyCompliance Certification Label orTire Label. The cold inflationpressure should never be set lowerthan the recommended pressureon the Safety ComplianceCertification Label or Tire Label.
When weather temperaturechanges occur, tire inflationpressures also change. A 10°F(6°C) temperature drop cancause a corresponding drop of1 psi (7 kPa) in inflation pressure.Check your tire pressuresfrequently and adjust them to theproper pressure which can befound on the Safety ComplianceCertification Label or Tire Label.
To check the pressure in yourtire(s):
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 mi(1.6 km), never bleed or reduce airpressure. The tires are hot fromdriving and it is normal forpressures to increase aboverecommended cold pressures. Ahot tire at or below recommendedcold inflation pressure could besignificantly under-inflated.
Note:If you have to drive adistance to get air for your tire(s),check and record the tire pressurefirst and add the appropriate airpressure when you get to thepump. It is normal for tires to heatup and the air pressure inside to goup as you drive.
2.Remove the cap from the valveon one tire, then firmly pressthe tire gauge onto the valveand measure 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 spare wheeland tire assembly information fora description. Store and maintainat 60 psi (412 kPa). For full-sizeand dissimilar spare tires, see theDissimilar spare wheel and tireassembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6.Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tireand cause an air leak.
7.Check the sidewalls to makesure there are no gouges, cutsor bulges.
Checking Pressure when tiresare hot:
If pressures are checked after tireshave been driven for more thanthree minutes or more than 1 mile,(2 km) the tires become hot andthe pressures will increase byapproximately 4 psi (27.6 kPa).Therefore when the tire pressureis adjusted under these conditions,it should be increased to a gaugereading of 4 psi (27.6 kPa) greaterthan the recommended coldinflation pressure.
For Example Only
33 psi (230kPa)Gauge readingof hot tire
32 psi (220kPa)If recom-mended, coldinflation pres-sure is
The hot tire pressure is only 1 psi(10 kPa) greater than therecommended cold inflationpressure. Therefore, add 3 psi(20 kPa) more to increase thehot pressure to 4 psi (30 kPa)over the recommended coldinflation pressure.
36 psi (250kPa)New hot pres-sure
Tire Inflation Information
WARNING: An inflated tireand rim can be very dangerousif improperly used, serviced ormaintained. To reduce the riskof serious injury, never attemptto re-inflate a tire which hasbeen run flat or seriouslyunder-inflated without firstremoving the tire from the wheelassembly for inspection. Do notattempt to add air to tires orreplace tires or wheels withoutfirst taking precautions toprotect persons and property.
All tires with Steel Carcass Plies(if equipped):
276
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingWheels and Tires

This type of tire utilizes steel cordsin the sidewalls. As such, theycannot be treated like normal lighttruck tires. Tire service, includingadjusting tire pressure, must beperformed by personnel trained,supervised and equippedaccording to Federal Occupational
Safety and Health Administrationregulations. For example, duringany procedure involving tireinflation, the technician orindividual must utilize a remoteinflation device, and ensure thatall persons are clear of thetrajectory area.

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 to2/32 inch (1.6 millimeters), tiresmust be replaced to help preventyour vehicle from skidding andhydroplaning. Built-in treadwearindicators, or wear bars, whichlook like narrow strips of smoothrubber across the tread appearson the tire when the tread is worndown to 2/32 inch (1.6millimeters).
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 or sidewall.If damage is observed orsuspected have the tire inspectedby a tire professional. Tires can bedamaged during off-road use, soinspection after off-road use isalso recommended.
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 asthose originally provided for yourvehicle. The recommended tireand wheel sizes can be found onthe Tire Label on the driver sidedoor frame or the edge of thedriver door. If this information isnot found in those locations, orfor additional options, contactyour authorized dealer. Use ofany tire or wheel notrecommended, could affect thesafety and performance of yourvehicle, 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: 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:
•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
WARNING: For a mountingpressure more than 20 psi(1.38 bar) greater than the
maximum pressure, a Forddealer or other tire serviceprofessional should do themounting.
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.
Replacing a Tire That isGreenhouse Gas Certified
The tires installed on this vehicleat the factory as originalequipment are certified forGreenhouse Gas and FuelEfficiency regulations.Replacement tires must be ofequal or lower rolling resistancelevel (TRRL or Crr). Consult withyour tire supplier(s) forappropriate replacement tires.
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.
HIGH SPEED DRIVING CAN BEDANGEROUS
Correct inflation pressure is
especially important. However, athigh speeds, even with the correctinflation pressure, a road hazardfor example is more difficult toavoid and if contact is made, has
281
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingWheels and Tires

on the road. If a tire is mounted byerror on the wrong-sized rim, donot remount it on the proper rim -scrap it. It may have beendamaged internally (which is notexternally visible) by having beendangerously stretched and couldfail on the highway.
Old valves may leak. When newtubeless tires are mounted,have new valves of the correcttype installed. Tubeless tiresmust only be mounted onwheels designed for tubelesstires i.e., wheels which havesafety humps or ledges.
It is recommended that you haveyour tires and wheels balanced.Tires and wheels, which are notbalanced, may cause steeringdifficulties, a bumpy ride, andirregular tire wear.
Be sure that all your valveshave suitable valve caps. Thevalve cap is the primary sealagainst air loss.
TEMPORARY SPARE TIRES
When using any temporary sparetire, be sure to follow the vehiclemanufacturer’s instructions.
