Tire traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly inflated or on slippery road surfaces.
Tires should be replaced when tread
wear indicators appear. Slow down whenever there is rain, snow or ice on
the road to reduce the possibility of
losing control of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire wear. If you find a tire is worn uneven‐
ly, have your dealer check the wheel
alignment.
When you have new tires installed, make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always be rebalanced if it is removed from the
wheel.
Tire sidewall labeling
0+'- 







This information identifies and de‐
scribes the fundamental characteristics of the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be used to identify the tire in case of a re‐
call.
1. Manufacturer or brand name
Manufacturer or Brand name is shown.
2. Tire size designation
A tire’s sidewall is marked with a tire size designation. You will need this in‐
formation when selecting replacement
tires for your vehicle. The following ex‐ plains what the letters and numbers in
the tire size designation mean.
Example tire size designation:
(These numbers are provided as an ex‐
ample only; your tire size designator could vary depending on your vehicle.)
P235/55R19 108T
P - Applicable vehicle type (tires
marked with the prefix L

this section for additional
information.
Wheel size designation
Wheels are also marked with important
information that you need if you ever have to replace one. The following ex‐
plains what the letters and numbers in
the wheel size designation mean. Example wheel size designation:
7.5JX19
7.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif‐ ferent speed ratings currently being
used for passenger car tires. The speed
rating is part of the tire size designa‐ tion on the sidewall of the tire. This
symbol corresponds to that tire's de‐
signed maximum safe operating speed.
SpeedRatingSymbolMaximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
SpeedRatingSymbolMaximum Speed
Z Above 240 km/h (149
mph)
3. Checking tire life (TIN: Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date, (in‐ cluding the spare tire) should be re‐
placed by new ones. You can find the
manufacturing date on the tire sidewall (possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consist‐ ing of numbers and English letters. The
manufacturing date is designated by
the last four digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and tread
pattern and the last four numbers indi‐ cate week and year manufactured.
For example:
DOT XXXX XXXX 1616 represents that
the tire was produced in the 16th week
of 2016.
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
L

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
(Continued)
(Continued)
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, we recom‐mend that you inspect the tirecondition or contact an authorizedKia dealer.
-To prevent damage to the tire, in‐spect the tire condition and pres‐sure every 3,000 km.
CAUTION
•It is not easy to recognize the tiredamage with your own eyes. But ifthere is the slightest hint of tiredamage, even though you cannotsee the tire damage with your owneyes, have the tire checked or re‐placed because the tire damagemay cause air leakage from thetire.
•If the tire is damaged by driving ona rough road, off road, pothole,manhole, or curb stone, it will notbe covered by the warranty.
•You can find out the tire informa‐tion on the tire sidewall.
