Second Stage: Checking Tire Pressure
Note:If you are proceeding from the FirstStage: Re-inflating the Tire with SealingCompound and Air section and have injectedsealant in the tire and the pressure is below20 psi (1.4 bar), continue to the next step.
WARNING
The power plug may get hot after useand should be handled carefully whenunplugging.
Check the air pressure of your tires asfollows:
1.Remove the valve cap from the tire valve.
2. Firmly screw the air compressor hoseonto the valve stem by turning clockwise.
3. Push and turn the dial clockwise to theair position.
4.If required, switch on the compressor andadjust the tire to the recommendedinflation pressure shown on the tire labellocated on the driver's door or door jambarea. You should check the tire pressurewith the compressor turned OFF in orderto get an accurate pressure reading.
5.Unplug the hoses, re-install the valve capon the tire and return the kit to thestowage area.
What to Do After the Tire has BeenSealed
After using the kit to seal your tire, you willneed to replace the sealant canister. Youcan obtain sealant canisters and spare partsat an authorized Ford dealer. You candispose of empty sealant canisters at home.However, you should dispose of canistersstill containing liquid sealant through yourlocal authorized Ford dealer or tire dealer,or in accordance with local waste disposalregulation.
Note:After you use the sealing compound,the maximum vehicle speed is 50 mph(80 km/h) and the maximum driving distanceis 120 mi (200 km). You should inspect thesealed tire immediately.
You can check the tire pressure any timewithin the 120 mi (200 km) by performing thesteps listed previously in the Second Stage:Checking Tire Pressure procedure.

TIRE CARE
Important Information About Low-Profile Tires
If your vehicle is equipped with265/40R21 tires, they are low-profiletires. These tires and wheels aredesigned to give your vehicle a sportappearance. With low-profile tires, youmay notice an increase in road noiseand faster tire wear, depending on roadconditions and driving styles. Due totheir design, low-profile tires and wheelsare more prone to road damage frompotholes, rough or unpaved roads, carwash rails and curb contact thanstandard tires and wheels.
Note:Your vehicle's warranty does not
cover these types of damages. Extracaution should be taken when operatingon rough roads to avoid impacts thatcould cause wheel and tire damage.

Important Information About SportTires and Wheels
Vehicles equipped with the optional265/40R21 tires are designed toenhance performance. To continueproviding this performance, extra caremust be taken when operating andmaintaining your vehicle.
These low-profile high-performance tiresare designed to optimize the drivingdynamics you expect in a sport vehiclein both dry and wet conditions. Thesetires are not optimized for off-road orwinter (snow or cold weather)performance; and their ride, noise, andwear characteristics are different thannon-performance tires. With low-profiletires, you may notice an increase in road
noise and faster wear, depending onroad conditions and driving habits. Also,because of their lower profile, the tiresare more susceptible to road damagefrom potholes, rough or unpaved roads,car wash rails, and curb contact thanstandard tires and wheels.
Note:Your vehicle’s warranty does notcover these types of damages. Extracaution should be taken when operatingon rough roads to avoid impacts thatcould cause wheel and tire damage.
The optional 265/40R21 tires weredesigned for track use and may exhibitsignificantly reduced tread life andincreased tire noise compared to thestandard equipment tires under normaldriving conditions. Increasing the frontcamber settings beyond the factorysettings may further accelerate treadwear and induce tire noise.
Note: Do not use tire chains on yourvehicle’s optional 265/40R21 tires andwheels. The use of any type of tire chainon these tires may damage your vehicle.
See Using Snow Chains (page 368).
Notice to Crossover Vehicle Owners
Crossover vehicles handle differentlythan passenger cars in the variousdriving conditions that are encounteredon streets, highways and off-road.Crossover vehicles are not designed forcornering at speeds as high aspassenger cars any more than low-slungsports cars are designed to performsatisfactorily under off-road conditions.

Crossover vehicles have a significantlyhigher rollover rate than other types ofvehicles. To reduce this risk of seriousinjury or death from a rollover or othercrash you must:
•Avoid sharp turns and abruptmaneuvers.
•Drive at safe speeds for theconditions.
•Keep tires properly inflated.
•Never overload or improperly loadyour vehicle.
•Make sure every passenger isproperly restrained.
WARNING
In a rollover crash, an unbeltedperson is significantly more likelyto die than a person wearing a seatbelt.
Information About Uniform Tire QualityGrading
Tire Quality Grades apply to newpneumatic passenger car tires. The TireQuality Grades can be found whereapplicable on the tire sidewall betweentread shoulder and maximum sectionwidth. For example: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that the UnitedStates Department of Transportation hasset.
Tire Quality Grades apply to newpneumatic passenger car tires. They donot apply to deep tread, winter-typesnow tires, space-saver or temporaryuse spare tires, light truck or LT typetires, tires with nominal rim diameters of10 to 12 inches or limited production tiresas defined in Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department of Transportation Tirequality grades: The U.S. Department ofTransportation requires Ford MotorCompany to give you the followinginformation about tire grades exactly asthe government has written it.
Treadwear
The treadwear grade is a comparativerating based on the wear rate of the tirewhen tested under controlled conditionson a specified government test course.For example, a tire graded 150 wouldwear 1 ½ times as well on thegovernment course as a tire graded 100.The relative performance of tires
354

depends upon the actual conditions oftheir use, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING
The traction grade assigned to thistire is based on straight-aheadbraking traction tests, and does notinclude acceleration, cornering,hydroplaning or peak tractioncharacteristics.
The traction grades, from highest tolowest are AA, A, B, and C. The gradesrepresent the tire’s ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade for this tireis established for a tire that isproperly inflated and not overloaded.Excessive speed, underinflation, orexcessive loading, either separately orin combination, can cause heat buildupand possible tire failure.
The temperature grades are A (thehighest), B and C, representing the tire’sresistance to the generation of heat andits ability to dissipate heat when testedunder controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can causethe material of the tire to degenerate
and reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which all
passenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing the originalequipment tire sizes, recommendedinflation pressure and the maximumweight the vehicle can carry.
*Tire Identification Number (TIN): Anumber on the sidewall of each tireproviding information about the tirebrand and manufacturing plant, tire sizeand date of manufacture. Also referredto as DOT code.
*Inflation pressure: A measure of theamount of air in a tire.

*Standard load: A class of P-metric orMetric tires designed to carry amaximum load at set pressure. Forexample: for P-metric tires 35 psi(2.4 bar) and for Metric tires 36 psi(2.5 bar). Increasing the inflationpressure beyond this pressure will notincrease the tire’s load-carryingcapability.
*Extra load: A class of P-metric or Metrictires designed to carry a heaviermaximum load at 42 psi (2.9 bar).Increasing the inflation pressure beyondthis pressure will not increase the tire’sload-carrying capability.
*kPa: Kilopascal, a metric unit of airpressure.
*PSI: Pounds per square inch, a standard
unit of air pressure.
*Cold tire pressure: The tire pressurewhen the vehicle has been stationaryand out of direct sunlight for an hour ormore and prior to the vehicle beingdriven for 1 mile (1.6 kilometers).
*Recommended inflation pressure: Thecold inflation pressure found on theSafety Compliance Certification Label(affixed to either the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver's seating position) or Tire Labellocated on the B-Pillar or the edge of thedriver’s door.
* B-pillar: The structural member at theside of the vehicle behind the front door.
*Bead area of the tire: Area of the tirenext to the rim.
* Sidewall of the tire: Area between thebead area and the tread.
*Tread area of the tire: Area of theperimeter of the tire that contacts the
road when mounted on the vehicle.
*Rim: The metal support (wheel) for atire or a tire and tube assembly uponwhich the tire beads are seated.
Information Contained on the TireSidewall
Both United States and Canada Federalregulations require tire manufacturersto place standardized information on thesidewall of all tires. This informationidentifies and describes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT Tire IdentificationNumber for safety standard certificationand in case of a recall.

Information on P Type Tires
P215/65R15 95H is an example of a tiresize, load index and speed rating. Thedefinitions of these items are listedbelow. (Note that the tire size, load indexand speed rating for your vehicle maybe different from this example.)
A. P: Indicates a tire, designated by theTire and Rim Association, that may beused for service on cars, sport utilityvehicles, minivans and light trucks. Note:If your tire size does not begin with aletter this may mean it is designated byeither the European Tire and RimTechnical Organization or the Japan TireManufacturing Association.
B. 215: Indicates the nominal width ofthe tire in millimeters from sidewall edgeto sidewall edge. In general, the largerthe number, the wider the tire.
C. 65: Indicates the aspect ratio whichgives the tire's ratio of height to width.
D. R: Indicates a radial type tire.
E. 15: Indicates the wheel or rim
diameter in inches. If you change yourwheel size, you will have to purchasenew tires to match the new wheeldiameter.
F. 95: Indicates the tire's load index. Itis an index that relates to how muchweight a tire can carry. You may find thisinformation in your owner’s manual. Ifnot, contact a local tire dealer.
Note:You may not find this informationon all tires because it is not required byfederal law.
G. H: Indicates the tire's speed rating.The speed rating denotes the speed atwhich a tire is designed to be driven forextended periods of time under astandard condition of load and inflationpressure. The tires on your vehicle mayoperate at different conditions for loadand inflation pressure. These speedratings may need to be adjusted for thedifference in conditions. The ratings
range from 81 mph (130 km/h) to186 mph (299 km/h). These ratings arelisted in the following chart.
Note:You may not find this informationon all tires because it is not required byfederal law.
