Relative service life expectancy for the tire, based on a US-specific standard
test. A tire with the specification 280 will wear 2.8 times more slowly than a
standard tire with a tread wear value of 100. The tire performance depends on
TREADWEAR 280
the usage conditions and may differ significantly from the standard values
depending on the driving behavior, maintenance, different road conditions, and
climate conditions.
Wet braking capability of the tire ( AA, A, B or C). The wet braking capability is
measured under controlled conditions on certified test courses. Tires marked

The labeling is on both sides of the tire. In some cases, certain codes may only be on one side of the tire, such as the tire ID number and the production date.
Other digits that may be present are part of the internal labeling from the tire manufacturer or country-specific labeling.
Low-profile tires
Compared to other tire-rim combinations, low-profile tires offer a wider tread surface and a larger rim diameter with shorter tire sidewalls. Low-profile tires improve
handling performance and precision. However, they may reduce the level of comfort when driving on roads in poor condition.
Unidirectional tires
The sidewalls on unidirectional tires are marked with arrows. The specified running direction must be followed. This ensures the optimum running characteristics.
If a tire is mounted opposite from the specified running direction, drive more carefully because the tire is not being used the way it was designed to be used. The tire
must be replaced or mounted in the correct running direction as soon as possible.
Asymmetrical tires
Asymmetrical tires factor in the behavior of the inner and outer areas of the tread pattern. The sidewalls on asymmetrical tires are marked as the inner and outer

UTQG tire classification
Uniform Tire Quality Grading (UTQG): Quality grades can be found where applicable on the tire sidewall between the tread shoulder and maximum section width.
Example:
Treadwear (number)
Traction AA, A, B or C
Temperature A, B or C
For example: Treadwear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements in addition to these grades.
324
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 (Treadwear-value 150) would wear one-and-one-half (1 1/2) times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving
habits, service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B, and C representing the tire's resistance to the generation of heat, and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
WARNING
The traction class assigned to this tire is based on traction tests when braking straight ahead and does not take account of the properties when accelerating,
driving around curves, hydroplaning or at maximum traction.
WARNING
The temperature class for this tire is based on a tire being inflated to the correct pressure and not being overinflated. Excess speeds, insufficient tire pressure,
and overinflation either alone or in combination can cause heat to build up and cause potential tire failure.
Tire load and vehicle load, determining the correct load
Vehicles and tires have a limited load capacity. An overloaded vehicle is difficult to steer and brakes less effectively. Overloading your vehicle can also cause
damage to the vehicle and tires, such as tire blowouts and sudden pressure losses.
To ensure your safety and the safety of your passengers, never exceed the maximum vehicle weight. This is specified as the Gross Vehicle Weight Rating
(GVWR).
The GVWR includes the weight of your vehicle including all additional equipment, all fluids and its maximum load. The maximum load includes the number of
people that can travel in the vehicle (number of seats) with an average weight of 150 lbs (68 kg) per person, and also luggage. In trailer mode, the weight of the
trailer and the trailer tongue weight rating must be included in calculations.
The Gross Axle Weight Rating (GAWR) is the maximum axle load per axle. The GVWR and GAWR are listed on the safety certificate on the B-pillar on the
driver's side.
Your vehicle has either 4 (2 front, 2 rear), 5 (2 front, 3 rear), 6 (2 front, 2 center, 2 rear) or 7 (2 front, 3 center, 2 rear) seats, depending on the type of vehicle. Each
seat has a safety belt. As there is an upper limit to the GVWR, the maximum load also has an upper limit. Traveling with a full vehicle or with passengers heavier
than 150 lbs (68 kg) per person will reduce the remaining possible load.
The tire inflation pressure label for your vehicle also specifies the maximum weight.
Determining the correct tire load
Never overload tires. The followingexample illustrates how to determinethe combined weight of all vehicleoccupants and luggage or othervehicle payloads. Never
overload thevehicle!
Steps for Determining Correct Load Limit:
1.
2.
3.
Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle's placard.
Determine the combined weight of the driver and passengers that will be riding in your vehicle.
Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the “XXX” amount equals 1400 lbs. and there
will be five 150 lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400–750 (5 × 150) = 650 lbs.)
4.
5.
Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.
325
Steps for Determining Correct Load Limit:
If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the
available cargo and luggage load capacity of your vehicle.
6.
Check the tire sidewall to determine the load index specified for thetire.
WARNING
Exceeding the maximum vehicle weight can cause you to lose control of the vehicle and cause accidents resulting in severe and/or fatal injuries.
Never exceed the maximum load or the maximum vehicle weight as per the GVWR.
