Vehicle Care

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage your vehicle.If you change the diameter of the tires fromthat fitted at the factory, the speedometermay not display the correct speed. If youintend to change the size of the wheels fromthat fitted by the manufacturer, you cancheck the suitability with an authorizeddealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 390).
You can find the recommended tire inflationpressures can on the Tire Label, which is onthe B-pillar or the edge of the driver door.You can also find this information on theSafety Compliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets the doorlatch post; next to the driver seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect the wayyour vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at least onceper month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Notice to utility vehicle and truckowners
WARNING: Utility vehicles have asignificantly higher rollover rate than othertypes of vehicles.
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly more likelyto die than a person wearing a seatbelt.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.

Wheels and Tires

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 one and one-half (1 ½) times as wellon the government course as a tiregraded 100. The relative performanceof tires depends upon the actualconditions of their use, however, andmay depart significantly from the normdue to variations in driving habits,service practices, and differences inroad characteristics and climate.
Traction AA A B C
WARNING: The traction gradeassigned to this tire is based onstraight-ahead braking traction tests,and does not include acceleration,cornering, hydroplaning or peaktraction characteristics.
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 temperaturegrade for this tire is established for atire that is properly inflated and notoverloaded. Excessive speed,underinflation, or excessive loading,either separately or in combination,can cause heat buildup and possibletire 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 cause
the material of the tire to degenerateand reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which allpassenger 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.

*PSI: Pounds per square inch, a standardunit 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

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.

Maximum Load: Indicates themaximum load in kilograms and poundsthat can be carried by the tire (affixed toeither the door hinge pillar, door-latchpost, or the door edge that meets thedoor-latch post, next to the driver'sseating position), or Tire Label locatedon the B-pillar or the edge of the driver'sdoor.
L. Treadwear, Traction andTemperature Grades:
*Treadwear: The treadwear grade is acomparative rating based on the wearrate of the tire when tested undercontrolled conditions on a specifiedgovernment test course. For example,a tire graded 150 would wear 1½ timesas well on the government course as a
tire graded 100.
*Traction: The traction grades, fromhighest to lowest are AA, A, B, and C.The grades represent the tire's ability tostop on wet pavement as measuredunder controlled conditions on specifiedgovernment test surfaces of asphalt andconcrete. A tire marked C may havepoor traction performance.
*Temperature: The temperature gradesare A (the highest), B and C,representing the tire's resistance to thegeneration of heat and its ability todissipate heat when tested undercontrolled conditions on a specifiedindoor laboratory test wheel.
M. Maximum Inflation Pressure:Indicates the tire manufacturers'maximum permissible pressure or the
pressure at which the maximum loadcan be carried by the tire. This pressureis normally higher than the vehiclemanufacturer's recommended coldinflation pressure which can be foundon the Safety Compliance CertificationLabel (affixed to either the door hingepillar, door-latch post, or the door edgethat meets the door-latch post, next to
the driver's seating position), or TireLabel located on the B-pillar or the edgeof the driver's door. The cold inflationpressure should never be set lower thanthe recommended pressure on thevehicle label.

Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver's door.See Load Carrying (page 287).
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tirepressure with a tire gauge (includingspare, if equipped). Inflate all tires to theinflation pressure recommended by us.
You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. We recommend the use ofa digital or dial-type tire pressure gaugerather than a stick-type tire pressuregauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
WARNING: Under-inflation is themost common cause of tire failuresand may result in severe tire cracking,tread separation or blowout, withunexpected loss of vehicle control andincreased risk of injury. Under-inflationincreases sidewall flexing and rollingresistance, resulting in heat buildup
