Maintenance
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
Temperature - A, B & C
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 condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grade C
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law. The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.

Maintenance
Pneumatic Tire

materials, that, when mounted on an
automotive wheel, provides the trac-
tion and contains the gas or fluid that
sustains the load.
Production Options Weight
The combined weight of installed
regular production options weighing
over 5 lb. (2.3 kg) in excess of the
standard items which they replace,
not previously considered in curb
weight or accessory weight, includ-
ing heavy duty brakes, ride levelers,
roof rack, heavy duty battery, and
special trim.
Recommended Inflation
Pressure
Vehicle manufacturer's recommend-
ed tire inflation pressure as shown
on the tire placard.
Radial Ply Tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at 90 degrees to the centerline of
the tread.
Rim
A metal support for a tire and upon
which the tire beads are seated.
Sidewall
The portion of a tire between the
tread and the bead.
Speed Rating
An alphanumeric code assigned to a
tire indicating the maximum speed at
which a tire can operate.
Traction
The friction between the tire and the
road surface. The amount of grip pro-
vided.
Tread
The portion of a tire that comes into
contact with the road.
Treadwear Indicators
Narrow bands, sometimes called
"wear bars", that show across the
tread of a tire when only 1/16 inch of
tread remains.
UTQGS
Uniform Tire Quality Grading
Standards is a tire information sys-
tem that provides consumers with
ratings for a tire's traction, tempera-
ture and treadwear. Ratings are
determined by tire manufacturers
using government testing proce-
dures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight
The number of designated seating
positions multiplied by 150 lbs. (68
kg) plus the rated cargo and luggage
load.

Maintenance
Vehicle Maximum Load on the
Tire
Load on an individual tire due to curb
and accessory weight plus maximum
occupant and cargo weight.
Vehicle Normal Load on the Tire
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and dividing by 2.
Vehicle Placard
A label permanently attached to a
vehicle showing the original equip-
ment tire size and recommended
inflation pressure.
All season tires
Genesis Branded Vehicle specifies
all season tires on some models to
provide good performance for use all
year round, including snowy and icy
road conditions. All season tires are
identified by ALL SEASON and/or
M+S (Mud and Snow) on the tire
sidewall. Snow tires have better
snow traction than all season tires
and may be more appropriate in
some areas.
Summer tires
Genesis Branded Vehicle specifies
summer tires on some models to
provide superior performance on dry
roads. Summer tire performance is
substantially reduced in snow and
ice. Summer tires do not have the tire
traction rating M+S (Mud and Snow)
on the tire side wall. If you plan to
operate your vehicle in snowy or icy
conditions, Genesis Branded Vehicle
recommends the use of snow tires or
all season tires on all four wheels.
Snow tires
If you equip your car with snow tires,
they should be the same size and
have the same load capacity as the
original tires. Snow tires should be
installed on all four wheels; other-
wise, poor handling may result. Snow
tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard tires
on the tire label on the driver's side of
the center pillar, or up to the maxi-
mum pressure shown on the tire
sidewall, whichever is less. Do not
drive faster than 75 mph (120 km/h)
when your vehicle is equipped with
snow tires.

Maintenance
Radial-ply tires
Radial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical pairs of radial-ply
tires should always be used as a set
for the front tires and a set for the
rear tires.Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
Low aspect ratio tires
Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
Because low aspect ratio tires are
optimized for handling and braking, it
may be more uncomfortable to ride
in and there is more noise compare
with normal tires.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.

When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.
CAUTION
✽ ✽
NOTICE
• It is permissible to add 3 psi to the standard tire pressure specification if colder temperatures are expected soon.
Tires typically loose 1psi (7kPa) for every 12°F temperature drop. If extreme temperature variations are expect-
ed, recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to
drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a proper level. (Air
inflation per altitude : +2.4 psi/1 mile)
