FORD F450 SUPER DUTY 2016 Owners Manual

The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade forthis tire is established for atire that is properly inflated andnot overloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heat
buildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlled conditionson a specified indoor laboratorytest wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under the
Federal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) or36 psi (2.5 bar) depending on tiresize and for Metric tires 36 psi(2.5 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.

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, checkyour 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-inflation is the mostcommon cause of tire failuresand may result in severe tirecracking, tread separation orblowout, with unexpected loss ofvehicle control and increased riskof injury. 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 (affixed to either thedoor hinge pillar, door-latch post,or the door edge that meets thedoor-latch post, next to thedriver's seating position), or TireLabel located on the B-pillar orthe edge of the driver's door.Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles.

Wheels and Tires

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.
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(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or Tire Label located on
the B-pillar or the edge of thedriver's door. 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 of 1psi (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 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.

Wheels and Tires

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 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).For full-size and dissimilar sparetires, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat the 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 tire andcause an air leak.
7. Check the sidewalls to makesure there are no gouges, cuts orbulges.
Tire Inflation Information
WARNING
An inflated tire and rim canbe very dangerous ifimproperly used, serviced ormaintained. To reduce the risk ofserious injury, never attempt tore-inflate a tire which has been runflat or seriously under-inflatedwithout first removing the tire
from the wheel assembly forinspection. Do not attempt to addair to tires or replace tires orwheels without first takingprecautions to protect personsand property.
All tires with Steel Carcass Plies(if equipped):
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 OccupationalSafety and Health Administrationregulations. For example, during

any procedure involving tireinflation, the technician orindividual must utilize a remote
inflation device, and ensure thatall persons are clear of thetrajectory area.
