Loading the vehicle
Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics and
lead to brake failure. There is a risk of acci-
dent.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
Two instruction labels on your vehicle showthe maximum possible load.
(1) The Tire and Loading Information placardis on the B-pillar on the driver's side. TheTire and Loading Information placardshows the maximum permissible numberof occupants and the maximum permissi-ble vehicle load. It also contains details ofthe tire sizes and corresponding pressuresfor tires mounted at the factory.
(2) The vehicle identification plate is on theB-pillar on the driver's side. The vehicleidentification plate informs you of thegross vehicle weight rating. It is made upof the vehicle weight, all vehicle occu-pants, the fuel and the cargo. You can alsofind information about the maximum grossaxle weight rating on the front and rearaxle.
The maximum gross axle weight rating isthe maximum weight that can be carriedby one axle (front or rear axle). Neverexceed the maximum load or the maxi-mum gross axle weight rating for the frontor rear axle.

You can find the valid maximum per-missible gross vehicle weight rating for yourvehicle on the Tire and Loading Informationplacard.

Determining the correct load limit
Step-by-step instructions
The following steps have been developed asrequired of all manufacturers under Title 49,Code of U.S. Federal Regulations, Part 575pursuant to the "National Traffic and MotorVehicle Safety Act of 1966".
XStep 1:Locate the statement "The com-bined weight of occupants and cargo shouldnever exceed XXX kg or XXX lbs." on yourvehicle’s Tire and Loading Information plac-ard.
XStep 2:Determine the combined weight ofthe driver and passengers that will be ridingin your vehicle.
XStep 3:Subtract the combined weight ofthe driver and passengers from XXX kilo-grams or XXX lbs.
XStep 4:The resulting figure equals the avail-able amount of cargo and luggage loadcapacity. For example, if the "XXX" amountequals 1400 lbs and there will be five 150-lbpassengers in your vehicle, the amount of
304Loading the vehicle
Wheels and tires

available cargo and luggage load capacity is650 lbs (1400 - 750 (5 x 150) = 650 lbs).
XStep 5:Determine the combined weight ofluggage and cargo being loaded on the vehi-cle. That weight may not safely exceed theavailable cargo and luggage load capacitycalculated in step 4.
Example: steps 1 to 3
The following table shows examples on how tocalculate total and cargo load capacities withvarying seating configurations and number andsize of occupants. The following examples usea load limit of 1500 lbs (680 kg).This is forillustration purposes only.Make sure youare using the actual load limit for your vehiclestated on your vehicle's Tire and Loading Infor-mation placard (Ypage 303).
The greater the combined weight of the occu-pants, the lower the maximum luggage load.

Gross Axle Weight Rating (GAWR):the maxi-mum permissible weight that can be carried byone axle (front or rear axle).
To ensure that your vehicle does not exceedthe maximum permissible values (gross vehi-cle weight and maximum gross axle weight rat-ing), have your loaded vehicle (including driver,occupants and the load) weighed on a suitablevehicle weighbridge.

Uniform Tire Quality Grading Stand-
ards
Overview of Tire Quality Grading
Standards
Uniform Tire Quality Grading Standards areU.S. government specifications. Their purposeis to provide drivers with uniform reliable infor-mation on tire performance data. Tire manu-facturers have to grade tires using three per-formance factors:Ctread wear grade,Dtraction grade and

surfaces that are not icy or covered with snow.Take appropriate care when driving.
Temperature
GWARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure.
The temperature grades are A (the highest), B,and C, representing the tire's resistance to thegeneration of heat and its ability to dissipateheat when tested under controlled conditionson a specified indoor laboratory test wheel.Sustained high temperature can cause thematerial of the tire to degenerate and reducetire life, and excessive temperature can lead tosudden tire failure. The grade C correspondsto a level of performance which all passengercar tires must meet under the Federal MotorVehicle Safety Standard No. 109. Grades Band A represent higher levels of performanceon the laboratory test wheel than the minimumrequired by law.

ROptionally, tires with a maximum speed ofover 149 mph (240 km/h) may have "ZR" inthe size description, depending on the man-ufacturer (e.g. 245/40 ZR18).
The service specification is made up of load-bearing index

wall of the tire. You will find this after the let-ter that identifies the speed rating(Ypage 307).
RIf no specification is given: no text (as in theexample above), represents a standard load(SL) tire
RXL or Extra Load: represents a reinforcedtire
RLight Load: represents a light load tire
RC, D, E: represents a load range thatdepends on the maximum load that the tirecan carry at a certain pressure
iTire data is vehicle-specific and may devi-ate from the data in the example.
Maximum load rating
Maximum tire loadCis the maximum permis-sible weight for which the tire is approved.
Do not overload the tires by exceeding thespecified load limit. The maximum permissibleload can be found on the vehicle's Tire andLoading Information placard on the B-pillar onthe driver's side (Ypage 303).
iThe actual values for tires are vehicle-spe-cific and may deviate from the values in theillustration.
DOT, Tire Identification Number (TIN)
US tire regulations stipulate that every tiremanufacturer or retreader must imprint a TINin or on the sidewall of each tire produced.
The TIN is a unique identification number. TheTIN enables the tire manufacturers or retread-ers to inform purchasers of recalls and othersafety-relevant matters. It makes it possiblefor the purchaser to easily identify the affectedtires.
The TIN is made up of manufacturer identifica-tion codeD, tire size
