WARNING
nTire age
Tires degrade over time, even whenthey are not being used.Regardless of the remaining tread,we recommend that tires be re‐placed after approximately six (6)years of normal service. Heat causedby hot climates or frequent highloading conditions can accelerate theaging process. Failure to follow thiswarning can result in sudden tirefailure, which could lead to a loss ofcontrol and an accident involving se‐rious injury or death.
4. Tire ply composition and material
The number of layers or plies of rub‐
ber-coated fabric in the tire. Tire man‐ ufacturers also must indicate the ma‐
terials in the tire, which include steel,
nylon, polyester, and others. The letter "R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means belted-bias ply construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum per‐ missible inflation pressure. Refer to the
Tire and Loading Information label for
recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as the factory installed tire.
7. Uniform tire quality grading
Quality grades can be found where ap‐
plicable on the tire sidewall between tread shoulder and maximum section
width.
For example:TREADWEAR 200TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire when tested under controlled con‐
ditions on a specified government test
course. For example, a tire graded 150 would wear one-and-a-half times (1½)
as well on the government course as a
tire graded 100.
The relative performance of tires de‐ pends upon the actual conditions of
their use, however, and may depart sig‐
nificantly from the norm due to varia‐
tions in driving habits, service practices and differences in road characteristics
and climate.
These grades are molded on the side-
walls of passenger vehicle tires. The tires available as standard or optional
equipment on your vehicle may vary
with respect to grade.
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 specified
government test surfaces of asphalt
and concrete. A tire marked C may have poor traction performance.
Maintenance
8-74
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 tem‐
perature can lead to sudden tire failure.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by
law.
WARNING
The traction grade assigned to thistire is based on straight-ahead brak‐ing traction tests, and does not in‐clude acceleration, cornering, hydro‐planing, or peak traction characteris‐tics.
WARNING
nTire temperature
The temperature grade for this tireis established for a tire that is prop‐erly inflated and not overloaded. Ex‐cessive speed, underinflation, or ex‐cessive loading, either separately orin combination, can cause heat build-up and possible sudden tire failure.This can cause loss of vehicle controland serious injury or death.
Low aspect ratio tire (if
equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided for sporty looks.
Because the 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.
CAUTION
Because the sidewall of the low as‐pect ratio tire is shorter than the

normal, the wheel and tire of thelow aspect ratio tire is easier to bedamaged. So, follow the instructionsbelow.•When driving on a rough road oroff road, drive cautiously becausetires and wheels may be damaged.And after driving, inspect tires andwheels.
•When passing over a pothole,speed bump, manhole, or curbstone, drive slowly so that thetires and wheels are not damaged.
•If the tire is impacted, inspect thetire condition or contact a profes‐sional workshop. Kia recommendsto visit an authorized Kia dealer/service partner.
•To prevent damage to the tire, in‐spect the tire condition and pres‐sure every 3,000km.
