2018 DODGE DURANGO SRT tire pressure

4. A tread life of up to 3,000 miles (4,800 km) can be expected depending
on road conditions and your driving habits. To conserve tire tread life,
the spare should be returned to the trunk as soon as the standard tire
can be repaired or replaced.
5. Because the YOKOHAMA high pressure spare tire was specifically
designed for your car, it should not be used on any other vehicle.
6. Do not use snow chains on your YOKOHAMA high pressure spare.
This could cause damage to your vehicle.
7. When the tread wear indicator appears on the tire, replace it only with
the same type spare tire.
8. Check the tire’s cold inflation pressure monthly and maintain at 60 psi
(4.2 kg/cm2) even when not in use. Do not inflate over 60 psi.
9. The YOKOHAMA high pressure spare tire should not be used with
any other rim nor should standard tires, wheel covers, or trim rings be
used on the YOKOHAMA high pressure spare tire rim on which the
YOKOHAMA high pressure spare tire was originally installed.
IMPORTANT SAFETY INFORMATION
All tires require owner maintenance regardless of how well a tire is
constructed. Operational damages such as punctures, impact damage, cuts,
incorrect inflation, etc., may cause tire failure and subsequent personal
injury and/or property damage. Simple operational and maintenance
practices, as listed below, will reduce the chances of tire problems.
Tire Inspection
Visually inspect your tires frequently for any tire damage such as scrapes,
bulges, cuts, nails, irregular wear, etc. resulting from operation. This must
be done immediately after any known or suspected contact with an object
in the road, a pothole, road irregularity or after severe braking. Refer
these conditions to a reputable tire service center for repair or replace-
ment. Never drive on a tire if such conditions appear.
Tire Loading
Never exceed the maximum vehicle load limit listed on the vehicle
placard, tire information label or in the owners manual. Be aware of the
load carrying limits molded into the tire’s sidewall and do not exceed
those limits. Maximum load can only be carried at the maximum cold
inflation pressure indicated on the tire’s sidewall.

Speed Limits
Regardless of the speed capability of your tires, never exceed lawful
speeds or speeds dictated by driving conditions.
Hazards
Objects in the road that could damage your tires should be safely
avoided. These objects include: potholes, glass, metal, rocks, wood debris
and the like. Unavoidable contact should prompt a thorough tire inspec-
tion.
Air Pressure
Air pressure maintenance is critical to tire service life. Tire pressures must
be checked frequently when tires are cold (before operation, cool to the
touch) and no less than once per month and before extended operation.
Use a tire gauge to check pressure and maintain it per the vehicle
manufacturer ’s recommendations (on vehicle placard or in owner ’s
manual). Do not reduce pressure when tire is hot and do not inflate a cold
tire higher than limits molded on the tire’s sidewall. Do not overlook
spare tire inflation pressure.
Tire Tread
Tires must be replaced when the depth of the tread reaches 2/32 inch
(1.6 mm). YOKOHAMA tires are manufactured with tread wear indica-
tors molded into the tire grooves which indicate tread wearout. As tires
wear down to 2/32 inch (1.6 mm), and tread depth is reduced, tire
traction is reduced during rainfall and winter road conditions. Visual tire
inspection therefore becomes more crucial as the tires wear out.
Hard Braking
You must inspect your tires after any hard braking situations or after tires
have slid on the pavement. This can cause a flat spot or other damage to
the tread of the tire.
Spinning
•Do not allow tires to spin at speeds greater than 35 mph if vehicle
becomes stuck.
•Do not stand behind a spinning tire while attempting to push a vehicle.
Speed and force can cause a tire to disintegrate and explode and may
cause property damage and/or personal injury.

TIRE HANDLING AND STORAGE IN COLDER CLIMATES
The rubber compounds used in the drag tires have unique properties
that, when compared to other tires, can cause them to lose some of their
flexibility when used or handled in conditions below 15°F (-9°C). This
loss in flexibility can lead to potential cracking and other damage to the
tire. To minimize the chances of this happening, you are advised to follow
these instructions:
1. Do not move or operate the car with these tires in conditions below
15°F (-9°C).
2. Avoid moving these tires in conditions below 15°F (-9°C).
3.
Before mounting and dismounting, store these tires for at least 24 hours
in a temperature-controlled environment of 68°F (20°C) or warmer.
4. Remove these tires from the vehicle and deflate to half the normal
air-pressure during prolonged periods of non-use or storage.
Always inspect tires for signs of cracking and never use tires that have
cracked.
WARNING!
DO NOT DRIVE ON THESE TIRES IN EXTREME COLD WEATHER
CONDITIONS. Driving or moving a vehicle with drag radial tires
installed in conditions below 15°F (-9°C) may cause cracking or other
damage to the tire. This can lead to tire failure, which may result in
loss of vehicle control and serious personal injury or death.
TIRE STORAGE
When dismounted from the wheel for storage, the drag tires should be
stored indoors in a cool, dry location. The tires should be placed away
from direct sunlight, harmful ozone-producing electric generators and
motors and sources of heat, such as hot pipes. Storage surfaces should be
clean and free of grease, gasoline, or other substances, which can
deteriorate the rubber.
WARNING!
Improper storage can damage your tires in ways that may not be
visible and result in tire failure, which may result in loss of vehicle
control, and lead to serious personal injury or death.

TIRE PRESSURE BASICS
The combined effect of losing 1 psi per month over several months along
with a 1 psi decrease for every 10°F temperature drop could add up to a
severe “run low” condition; consequently, it is important to check your
tires’ inflation pressure at least once per month.
Inflation pressure enables a tire to support its load; therefore, proper
inflation is critical.
HOW TO DETERMINE PROPER TIRE INFLATION PRESSURE
It is impossible to determine whether tires are properly inflated just by
looking at them.

It is important to check your tires using an accurate tire pressure gauge,
which can be purchased at your tire dealer or auto supply store.
Underinflation can overload tires. Check the inflation pressure every
month, including for the spare tire, to make sure it’s up to specification.
Check it again before long trips or when carrying extra weight.
Look for the manufacturer ’s recommended inflation pressure listed on
the Tire Information Placard usually located on your vehicle’s door edge,
door post, glove box, or inside the trunk lid.
mNOTICE!
The inflation pressure shown on the sidewall of the tire is not the intended
inflation pressure for the vehicle! Always refer to the vehicle’s Tire
Information Placard.

WARNING!
Driving on tires with insufficient inflation pressure is dangerous
because it will cause your tires to overheat. This can cause sudden
tire failure, which may result in loss of vehicle control and lead to
serious personal injury or death.
