winter tires DODGE CHALLENGER 2018 Vehicle Warranty

•Follow recommendations in the vehicle Owner ’s Manual for winter
tires, studs, and chains.
•Consult your tire dealer, the Rubber Manufacturers Association web-
site
www.rma.org, or your state’s Department of Transportation
(DOT) for information regarding regulatory and seasonal restrictions
for stud usage.
•Also see the “Tire Mixing” section in this manual for more details.
•Toyo Tires recommends that snow tires be installed in matched sets of
four.
ADVERSE WEATHER DRIVING
Take special care when driving in adverse weather conditions.
•Rain and snow – Driving in rain or snow considerably reduces the
traction between your tires and the road surface. You must always
reduce your speed to allow additional stopping distance between you
and the vehicles ahead of you.
•Hydroplaning and wet weather driving – Hydroplaning occurs on wet
roads and refers to the loss of tire contact with the road due to the
build-up of water between the tire contact patch and the road surface.
Three main factors affect hydroplaning and, consequently, your tire
traction on wet roads:
1. Vehicle Speed – As speed increases, wet traction is considerably
reduced.
2. Water Depth – The deeper the water, the sooner your tires will lose
traction. Even thin water layers can create sufficient lubrication to
cause traction loss at low speeds, depending on road conditions.
3. Tire Tread Depth – As your tires wear down, their decreased ability to
resist hydroplaning can result in a complete loss of traction and
vehicle control. You should always reduce your speed with consider-
ation for the traffic around you.
•Driving on ice and snow – Your all-season tires were designed to
provide higher levels of snow traction compared to non-all- season
tires. You have all-season tires if you find the letters “M&S” are molded
into the sidewall near the bead. These letters mean “Mud and Snow.”
Tires designed for use in severe snow conditions generally have tread
patterns, structure, and materials for giving superior performance.

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.

FOUR-WHEEL DRIVE (4WD) AND ALL-WHEEL DRIVE (AWD)
VEHICLES
If no instructions for tire mixing appear in the vehicle Owner ’s Manual,
follow these guidelines:
•Do not mix tire sizes. All four tires must be marked with the same tire
size, unless otherwise specified by the vehicle manufacturer. This also
applies to winter/snow tires.
•Do not mix tread pattern types such as all-terrain and all- season.
STUDLESS WINTER/SNOW TIRES
•It is always preferable to apply winter/snow tires to all wheel
positions, including dual tires, to maintain vehicle mobility and
control.
•If winter/snow tires are applied to the front axle of any vehicle,
winter/snow tires must also be installed on the rear axle. DO NOT
apply winter/snow tires only to the front axle. This applies to all
passenger and light truck vehicles, including front-wheel- drive, 4WD,
and AWD vehicles.
•If winter/snow tires are installed on the rear axle of any vehicle, it is
recommended (but not required) that they also be installed on the front
axle.
WARNING!
Unless winter/snow tires on the rear axle have comparable traction
qualities to the tires on the front axle, the vehicle may experience
adverse handling characteristics. This may result in loss of vehicle
control, which can lead to serious personal injury or death.
STUDDED WINTER/SNOW TIRES
•Studded winter/snow tires have higher traction qualities under most
winter weather conditions.
•If studded winter/snow tires are installed on the front axle of any
vehicle, studded winter/snow tires must also be installed on the rear
axle. DO NOT apply studded winter/snow tires only to the front axle.
•If studded winter/snow tires are installed on the rear axle of any
vehicle, it is strongly recommended that they should also be installed
NITTO TIRE

on the front axle. Only if studded winter/snow tires are installed on all
wheel positions of a vehicle will optimum handling characteristics be
achieved.
WARNING!
Installing only two studded winter/snow tires on the front axle of
any vehicle (including front-wheel-drive vehicles) without studded
winter/snow tires on the rear axle can cause adverse vehicle
handling characteristics. This can result in a loss of vehicle control,
which could cause serious personal injury or death.
mNOTICE!
In some cases, the vehicle manufacturer may specifically advise against
replacing fewer than all four tires. Always check and follow the
recommendations in the vehicle Owner’s Manual. For 4WD and AWD
vehicles, even small differences in outside diameter may cause drivetrain
damage or mechanical malfunction.
REPLACING TWO TIRES
•When a pair of replacement tires is selected in the same size and
construction as those on the vehicle, the two newer tires must be
installed on the rear axle and must be of equal or higher speed rating
than the front tires. Generally, new tires with deeper tread will provide
better grip and evacuate water more effectively, which is important as
a driver approaches hydroplaning situations. Placing greater traction
on the rear axle on wet surfaces is necessary to prevent a possible
oversteer condition and loss of vehicle stability.
•When two new tires have been installed onto the rear axle positions,
they are to be kept on the rear but rotated from side to side. This is
recommended after installing two new tires to the rear position, or if
you discover significant tread depth differences between the front and
rear positions during rotation intervals.

the speed capability is limited by the speed symbol in the service
description (i.e., 235/45ZR17 97W = maximum speed 168 mph
[270 km/h]).
** Although no upper limit speed is specified, the indicated tires
nonetheless have limited rated speed capability. Call 888–529-8200 Pacific
Time for a referral for more technical information.
mNOTICE!
Tire speed symbols do not imply that vehicles can be safely driven at the
maximum speed for which the tire is rated, particularly under adverse road
and weather conditions, or if the vehicle has unusual characteristics. Never
operate a vehicle in an unsafe or unlawful manner.
TIRE SPINNING
WARNING!
Spinning a tire to remove a vehicle stuck in mud, snow, or wet grass
can be dangerous. This could cause serious personal injury or death to
a bystander or passenger and extensive vehicle damage. A tire
spinning at a speedometer reading above 35 miles per hour (55 km/h)
can reach a speed capable of disintegrating a tire with explosive force
within a matter of seconds. Under some conditions, a tire may be
spinning at twice the speed shown on the speedometer. Never spin a
tire above a speedometer reading of 35 mph (55 km/h). Never allow
anyone to stand near or directly behind the spinning tire. Do not spin
if a drive wheel is off the ground.
TOWING OR USE OF SLIDE-IN TRUCK CAMPERS
If you are towing a trailer or using a slide-in truck camper, refer to your
vehicle Owner ’s Manual.
WINTER (SNOW) TIRES
Winter driving presents special challenges for vehicle
handling. The use of winter tires, studs, and chains, while
improving traction performance in snow and ice, requires
additional caution and care with regard to braking, corner-
ing, and speed. It is important to drive with care not only
on snow and ice, but on dry and wet roads as well.
NITTO TIRE

WARNING!
Studded tires may require longer braking distances on dry or wet
paved surfaces. Failure to allow for adequate braking distance could
result in serious personal injury or death.
•Traction is considerably reduced as snow tires approach 50% tread
wear, and replacement should be considered in order to maintain
effectiveness in heavy snow conditions.
•Tire speed rating – When lower-speed-rated winter tires replace
higher-speed-rated touring and high performance all-season radial
tires, do not exceed the lower-rated speed.
•Follow recommendations in the vehicle Owner ’s Manual for winter
tires, studs, and chains.
•Consult your tire dealer, the Rubber Manufacturers Association web-
site
www.rma.org, or your state’s Department of Transportation
(DOT) for information regarding regulatory and seasonal restrictions
for stud usage.
•Also see the “Tire Mixing” section in this manual for more details.
•Nitto recommends that snow tires be installed in matched sets of four.
ADVERSE WEATHER DRIVING
Take special care when driving in adverse weather conditions.
•Rain and snow – Driving in rain or snow considerably reduces the
traction between your tires and the road surface. You must always
reduce your speed to allow additional stopping distance between you
and the vehicles ahead of you.
•Hydroplaning and wet weather driving – Hydroplaning occurs on wet
roads and refers to the loss of tire contact with the road due to the
build-up of water between the tire contact patch and the road surface.
Three main factors affect hydroplaning and, consequently, your tire
traction on wet roads:
A. Vehicle Speed – As speed increases, wet traction is considerably
reduced.
