2020 CHRYSLER 300 traction control

•EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER
MOUNTING. Only specially trained persons should mount tires.
• FAILURE TO MOUNT RADIAL TIRES ON APPROVED RIMS.
• FAILURE TO DEFLATE SINGLE OR DUAL ASSEMBLIES COM-
PLETELY BEFORE DEMOUNTING.
• TIRE SPINNING. On slippery surfaces such as snow, mud, ice, etc.,
do not spin tires in excess of 35 mph (55 kph), as indicated on the
speedometer.
• EXCESSIVE WHEEL SPINNING. This can also result in tire disinte-
gration or axle failure.
WARNING!
Vehicle handling, traction, ride comfort and other performance
parameters may be significantly affected by a change in tire size or
type. Before replacing tires, always consult and follow the vehicle
owner ’s manual because some vehicle manufacturers prohibit
changing tire size. When selecting tires that are different from the
original equipment size make certain:
1. The tires have adequate load-carrying capacity based on the vehicle placard,
2. The tires have sufficient inflation pressure to carry the load and
3. There is proper clearance with no interference points between the tire and vehicle.
The consumer must be aware to always drive safely and obey all
traffic laws. Avoid sudden, sharp turns or aggressive lane changes.
Failure to follow any of these warnings may result in loss of control
of the vehicle, leading to an accident and serious injury or death.
TIRE CARE AND MAINTENANCE GUIDE
The easiest way to help ensure satisfactory mileage and performance
from your Goodyear or Dunlop tires is to give them a simple but frequent
(at least monthly) inspection for proper inflation, even tread wear and the
presence of any damage.
DO MAINTAIN PROPER INFLATION PRESSURE IN YOUR TIRES
Proper inflation pressure is necessary for optimum tire performance,
safety and fuel economy. Check inflation pressures at least once a month
and before long trips. Use an accurate tire pressure gauge. Always check

•Inspect your tires for adequate tread depth. When the tire is worn to
the built-in indicators at 2/32” (1.6 mm) or less tread groove depth, the
tire is worn out and must be replaced. Never drive on tires to the point
that the tire cord or the fabric is exposed.
• Inspect your tires for uneven wear. Wear on one side of the tread or flat
spots in the tread may indicate alignment or other problems with the
tires or the vehicle. Consult your authorized Toyo Tires dealer.
WARNING!
Never drive on a tire if there is any evidence of damage. Driving on
a damaged tire is dangerous. A damaged tire could suddenly fail,
which may result in loss of vehicle control and lead to serious
personal injury or death. Do not attempt to dismount, mount, or
repair a tire yourself. See your Toyo Tires dealer immediately if you
detect damage.
IDENTIFYING DAMAGED WHEELS
Periodically check to see if any of the following symptoms exist, in which
case the wheel must be replaced:
•If the flange is bent.
• If welds or rivets are leaking.
• If the stud holes are elongated and not round. (Improper lug nut
tightening could cause this.)
• If there are cracks in the wheel.
WORN OUT TIRES
Tires must be replaced when tread is worn to 2/32” (1.6 mm). Treadwear
indicators on Toyo tire treads show the 2/32” depth (1.6 mm). Most states
require that tires be replaced when the tread depth is worn to 2/32” (1.6
mm). Tires may lose sufficient wet and snow traction before reaching
2/32” (1.6 mm) of wear. Many wet weather accidents result from
skidding on worn out tires.
Excessively worn tires are more susceptible to penetrations. Consider
replacing your tires earlier if you drive in snow or wet conditions.

of the replacement tire. Vehicle handling could also be affected.
Consult the vehicle Owner ’s Manual or tire manufacturer for
recommendations.
• If tires with different speed ratings are used, it is recommended that
the lowerspeed- rated tires always be placed on the front axle. This is
to prevent a potential oversteer condition.

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.

• 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.

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.
m NOTICE!
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.
