Wheels and TiresNote: 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.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.Inspecting Your Tires andWheel Valve StemsPeriodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves. Check the tireand valve stems for holes, cracks,or cuts that may permit airleakage and repair or replace thetire and replace the valve stem.Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredemounted and inspected in case277F150 (TF6) , enUSA
