2020 DODGE DURANGO tires

Additional notes about tire repairs:
•Not all punctured or damaged tires can be properly repaired; conse-
quently, they must be replaced. NEVER repair a tire with any of the
following conditions:
– Wear to the tire’s built-in tread wear indicators or to 2/32 inch (1.6 mm) remaining tread depth in any area of the tread.
– With a puncture larger than 1/4 inch (6 mm).
– With a puncture or other damage outside the repairable tread area (as shown in the graphic).
– With a pre-existing, improper repair.

•Any tire repair done without removing the tire from the wheel is
improper. The tire must be demounted from the wheel and the interior
inspected for damage that may not be evident on the exterior of the
tire.
• Using only a plug/stem, or using only a patch, is not a safe or proper
repair. A patch must be applied to the interior of the tire and the
puncture hole must be filled with a suitable plug/stem filler to prevent
inflation pressure loss and contamination of the steel belts and other
plies.
• NEVER substitute a tube for a proper repair or to remedy an improper
repair.
• Tubes, like tires, should only be repaired by a qualified tire service
professional.
• Some vehicle manufacturers do not recommend using repaired tires.
Consult your vehicle owner ’s manual or contact the vehicle manufac-
turer before operating a repaired tire on your vehicle.
ASK how your tire will be repaired. ALWAYS insist on a proper tire
repair.
Emergency/Temporary Sealant or Filler Repairs: An emergency/
temporary sealant or filler injected into the tire, such as by aerosol can or
injection/squeeze-tube, is not a proper repair and voids the tire Limited
Warranty. A tire injected with such sealant/filler must be replaced by a
qualified tire service professional as soon as possible.
WARNING!
Tell the tire service professional if you have used an aerosol fixer to
inflate/seal the tire. Aerosol fixers could contain a highly volatile
gas. Always remove the valve core outdoors, away from sources of
excessive heat, flame, or sparks and completely deflate the tire
before removing it from the wheel.
Speed Rating: The tire’s speed rating is void if the tire is repaired,
retreaded, damaged, abused, or otherwise altered from its original
condition. Thereafter, it should be treated as a non-speed rated tire. See
“Tire Speed Ratings” in this manual.
Improper repair voids the tire Limited Warranty. See “Limited War-
ranty” in this manual.

RFT (Run-Flat Technology) Tires:In addition to the above, there are
recommendations specific to the repair of RFT tires; see “RFT Tires with
Run-Flat Technology” in this manual.
TIRE MOUNTING AND OTHER SERVICING
WARNING!
Removing and replacing tires on wheels can be dangerous.
Attempting to mount tires with improper tools or procedures may
result in a tire explosion causing serious personal injury or death.
This is only a job for a qualified tire service professional. Never
perform tire service procedures without proper training, tools, and
equipment.
This manual is not intended to provide proper training or service
procedures for tire mounting, demounting, balancing, rotation, or
repair. Please leave these tasks to qualified tire service professionals.
For your safety and that of others:
• Always stand well clear of any tire mounting operation. This is
especially important when the service operator inflates the tire. If the
tire has been improperly mounted, it may burst with explosive force
causing serious personal injury or death.
• Tires must match the width and diameter requirements of the wheels.
For example, 16 inch diameter tires must only be mounted to 16 inch
diameter wheels. Radial tires must only be mounted to wheels
approved for radial tires.
• Wheels must be free of cracks, dents, chips, and rust. Tires must be free
of bead damage, cuts, and punctures.
• Never inflate a tire beyond 40 psi (275 kPa) to seat the beads. Be
absolutely certain beads are fully seated before adjusting inflation
pressure to the level recommended for vehicle operation.
• Never put flammable substances in tire/wheel assemblies at any time.
Never put any flammable substance into a tire/wheel assembly and
attempt to ignite to seat the beads.
• Always stand well away from the work area when tires are being spin
balanced either on or off the vehicle.

HIGH PERFORMANCE, LOW ASPECT RATIO TIRES
Many new vehicles come equipped from the factory with high perfor-
mance and/or low aspect ratio tires. Generally, these tires provide
increased vehicle handling capability, but may also have numerous
engineering performance trade-offs associated with their designs.
•Low aspect ratio tires, with reduced sidewall height, may be more
susceptible to damage from potholes, road hazards, and other objects
such as curbs. This is true for the wheels as well. Therefore, as with all
other tires, it is important to drive with care and maintain proper
inflation pressure and load conditions. See “Tire Inflation Pressure”
and “Tire Damage, Inspection and Service Life” in this manual.

TIRE MIXING
WARNING!
Driving your vehicle with an improper mix of tires is dangerous.
Your vehicle’s handling characteristics can be seriously affected. You
could have an accident resulting in serious personal injury or death.
Consult your vehicle owner ’s manual and a qualified tire service
professional for proper tire replacement.
HIGH SPEED DRIVING
WARNING!
Driving at high speed is dangerous and can cause a vehicle accident,
including serious personal injury or death.
• Regardless of the speed and handling capabilities of your car and its
tires, a loss of vehicle control can result from exceeding the maximum
speed allowed by law or warranted by traffic, weather, vehicle, or road
conditions.
BRIDGESTONE® - FIRESTONE®

•High-speed driving should be left to trained professionals operating
under controlled conditions.
• No tire, regardless of its design or speed rating, has unlimited capacity
for speed, and a sudden tire failure can occur if its limits are exceeded.
See “Tire Speed Ratings,” the next section in this manual.
Refer to your vehicle owner ’s manual for any tire pressure recommen-
dations for high speed driving.
TIRE SPEED RATINGS
A tire bearing a letter “speed rating” designation indicates the tire’s
speed capability according to standardized laboratory tests. This speed
rating system is intended to permit comparison of the speed capabilities
of different tires. When replacing your tires, consult your vehicle owner ’s
manual and tire information placard for recommendations, if any,
concerning the use of speed rated tires.
• To avoid reducing the speed capability of the vehicle, replace a speed
rated tire only with another tire having at least the same speed rating.
It is the “top speed” of the “slowest” tire on the vehicle which limits
the vehicle’s top speed without tire failure.
• The tire’s speed rating is void if the tire is repaired, retreaded,
damaged, abused, or otherwise altered from its original condition.
Thereafter, it should be treated as a non-speed rated tire.
• Non-speed rated tires are usually for ordinary passenger car or light
truck service and not for high speed driving.
• For


tires
used
in
cold
weather
conditions,
it
is
generally

acceptable
to
apply
a
tire
with
a
lower
speed
rating
than
your
original

tires;
however,
speed
should
be
reduced
accordingly.
All


tires
should
be
the
same
speed
rating.
Some
vehicles
have
specific

recom-mendations
regarding

tire
use;
consult
your
vehicle

owner ’s
manual
and


tire
information
placard.
See
“

Tires”
in
this
manual.
These speed ratings are based on standardized laboratory tests under
specific, controlled conditions. While these tests may relate to perfor-
mance on the road, real-world driving is rarely identical to any test
conditions. Your tire’s actual speed capability may be less than its rated
speed since it is affected by factors such as inflation pressure, load, tire

condition (including damage), wear, vehicle condition (including align-
ment), driving conditions, and duration at which the speed is sustained.
Use the following chart to compare the speed ratings of tires.
Speed
Symbol Speed Category*
mph km/h
M8 1130
Q9 9160
R 106 170
S 112 180
T 118 190
U 124 200
H 130 210
V 149 240
Z** >149 >240
W 168 270
Y 186 300
(Y)** >186
The tire’s speed rating designation appears on the tire sidewall with the
tire size. Examples:
P275/40ZR17 max > 149 mph (240 km/h)****
P275/40R17 93W max = 168 mph (270 km/h)
P275/40ZR17 93W max = 168 mph (270 km/h)
P275/40ZR17 93Y max = 186 mph (300 km/h)
P275/40ZR17 93(Y) max > 186 mph (300 km/h) ****
* In standardized laboratory tests that relate to highway speeds. Actual
tire speed and performance capability depend on factors such as inflation
pressure, load, tire condition, wear, and driving conditions.
** Any tire having a maximum speed capability above 149 mph
(240 km/h) may, at the tire manufacturer ’s discretion, include a “Z” in
the size designation (i.e. P275/40ZR17).
*** For tires having a maximum speed capability above 186 mph
(300 km/h), a “Z” must appear in the size designation and a “Y” marked
in brackets (as shown) in the service description.
**** Consult the tire manufacturer for maximum speed capability.

TIRE SPINNING
WARNING!
Spinning a tire to remove a vehicle stuck in mud, ice, snow, or wet
grass can be dangerous. A tire spinning at a speedometer reading
above 35 mph (55 km/h) can in a matter of seconds reach a speed
capable of disintegrating a tire with explosive force. Under some
conditions, a tire may be spinning at a speed twice that shown on
the speedometer. This could cause serious personal injury or death
to a bystander or passenger. Never spin a tire above a speedometer
reading of 35 mph (55 km/h).
RADIAL TIRE ROTATION
The purpose of tire rotation is to minimize irregular or uneven wear
caused by maintaining a tire in one rotation direction and one position
over an extended period. Rotate tires as recommended by the vehicle
manufacturer or every 5,000 miles. Individual tire pressures must be
checked after rotation and adjusted to the vehicle manufacturer ’s recom-
mendation for the tire’s new location on the vehicle. Vehicle alignment
should be checked if irregular wear is evident.
For vehicles with a “temporary use” spare tire, follow the vehicle
manufacturer ’s recommended pattern for rotation, or, if not provided, the
following may be used:
