2018 DODGE DURANGO SRT tires

USEFUL TIRE INFORMATION
There is a lot of useful information molded into the sidewall of a tire. It
shows the name of the tire, its size, if it is tubeless or tube type, the
maximum load and maximum inflation, and important safety warnings.
The sidewall markings on passenger and light truck tires are slightly
different.
TYPICAL PASSENGER TIRE
The letters “DOT” certify compliance with all applicable safety standards
established by the U.S. Department of Transportation (DOT). Adjacent to
this is a tire identification or serial number. This serial number is a code
with up to 12 digits that are a combination of numbers and letters. The
last characters are numbers identifying the week and year of manufac-
ture. (For example, “1502” means the fifteenth week of the year 2002.)

The DOT requires tire manufacturers to grade passenger car tires based
on three performance factors: Treadwear, Traction and Temperature
resistance. (See the “Uniform Tire Quality Grading (UTQG)” section for
more details.)
The sidewall also shows the type of cord and the number of plies in the
sidewall and under the tread.
TYPICAL LIGHT TRUCK TIRE
UNIFORM TIRE QUALITY GRADING (UTQG)
The Uniform Tire Quality Grading (“UTQG”) standards are intended to
assist you in making an informed choice in your purchase of passenger
car tires by providing information indicating relative performance in the
areas of treadwear, wet stopping traction, and temperature resistance. All
passenger car tires must conform to federal safety requirements in
addition to these grades.

•Treadwear - The treadwear grade is a comparative rating based on the
wear rate of the tire tested under controlled conditions on a specified
government test track. For example, a tire graded 200 would wear
twice as long on the government course as a tire graded 100. It is
wrong to link treadwear grades with your projected tire mileage. The
relative performance of the tires depends upon the actual conditions of
their use and may vary due to driving habits, service practices,
differences in road characteristics, and climate.
•Traction - The traction grades from highest to lowest are AA, A, B, and
C, and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.
mNOTICE!
The traction grade assigned to tires is based on locked braking (straight
ahead) traction tests and does not include cornering (turning) traction.
•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 temperatures
can cause the materials 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 that all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 139. Grades
B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade is established for a tire that is properly
inflated and not overloaded. Excessive speed, underinflation, or
excessive loading either separately or in combination can cause heat
buildup and possible tire failure. This can cause an accident, which
could lead to serious personal injury or death.
•DOT Quality Grades - All passenger car tires must conform to federal
requirements in addition to these grades.

DOT SERIAL NUMBER SYSTEM
TIRE REGISTRATION
Your original equipment tires are registered through the vehicle manu-
facturer.
When you purchase replacement Nitto brand tires, the seller is required
by the National Highway Traffic Safety Administration to present you
with a tire registration form. Nitto Tire U.S.A. Inc. provides a registration
card at no charge to all Nitto dealers. The dealer must fill in the dealer
name, address, and serial numbers of the tires purchased. You, the buyer,
should then fill in your name and address, place a stamp on the form, and
mail it to the pre- addressed location on the form. Be sure to have your
dealer complete their portion of the registration card included in this
NITTO TIRE

Limited Warranty at the time of purchase. The information contained in
the registration card is an important means to notify you in the event of
a product recall.
If you prefer, you may register your tires on our web page at
www.nittotire.comand select “Tire Registration.” Be prepared to pro-
vide the name and address of the dealer, the quantity of tires, and the
DOT serial numbers from the sidewall of the tires.
IMPORTANT! If self-registering tires, make sure to include all letters and
numbers (up to 12 digits) following the letters “DOT” on the tire’s
sidewall near the bead. If you see only four letters next to the letters
“DOT”, look on the other side of the tire for the full DOT number.
