wheel size HYUNDAI I20 2018 Owners Manual

Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding\b
rapid acceleration\b sudden brake
applications\b and sharp turns are
potentially very hazardous practices.
During deceleration\b use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow\b it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains\b tow straps
or chains\b a flashlight\b emergency
flares\b sand\b a shovel\b jumper cables\b
a window scraper\b gloves\b ground
cloth\b coveralls\b a blanket\b etc.
Snow tires
If you mount snow tires on your vehi
cle\b make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipmenttires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local and municipal reg
ulations for possible restrictions
against their use\b
i
W(&$'#

#(V(&
Snow tires should be equivalent in
size and type to the vehicle's stan
dard tires. Otherwise\b the safety
and handling of your vehicle may
be adversely affected.
WARNING

When using tire chains:
• Wrong size chains or improperlyinstalled chains can damage your
vehicle's brake lines\b suspension\b
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains contacting the body\b retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage\b retighten the chains after driving \f.5~1.\f km
(\f.3~\f.6 miles).
• Do not use tire chains on vehic
les
equipped with aluminum wheels. If
unavoidable\b use a wire type
chain.
• Use wire chains less than 15 mm (\f.59 in) wide to prevent damage
to the chain’s connection.
Winter precautions
Use high quality ethylene glycolcoolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool
ing system\b lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter\b
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
Change to "winter weight" oil if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use\b we recommend that you
consult with an authorized HYUNDAI
dealer.
Check spark plugs and ignition system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked\b worn or
damaged in any way.

When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure afterinstalling the compact spare tire.
The compact spare tire should be
inflated to 420 kPa (60 psi).
• Do not take this vehicle through an automatic car wash while the com-
pact spare tire is installed.
• Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
• The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact spare tire at a time.
• Do not tow a trailer while the com- pact spare tire is installed.
IInformation
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly to prevent wheel vibration. The
correct lug nut tightening torque is
11~13 kgf.m (79~94 lbf.ft).
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road condition s to avoid all hazards,
such as a potholes or debris.
• Avoid driving over obstacles. The compact spare t ire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance appr oximately
25 mm (1 inch).
• Do not use tire chains on the com- pact spare tire. Because of the
smaller siz e, a tire chain will not fit
properly.
• Do not use the compact spare tire on any other wheels, nor shoul d
standard tires, snow tires, wheel
covers or trim rings be used with
the compact spare wheel.NOTICE

!$# "#$$#Tire care For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. Recommended cold tire inflation
pressures All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in chapter
8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
OIB074055
Tire underinflation
Severe underinflation (70 kPa (10
psi) or more) can lead to severe
heat build-up, ca using blowouts,
tread separation and other tire fail-
ures that can result in the loss of
vehicle contro l leading to severe
injury or death. This risk is much
higher on hot days and when driv-
ing for long pe riods at high
speeds.
WARNING

1.(%,204/3424-3TTire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 10,000 km (6,200 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to “Tire and wheels” in chapter
8. Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
Rotate radial tires that have an asym-
metric tread pattern only from front
to rear and not from right to left.i•
Do not use the compact spare
tire for tire rotation.
•
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling ch aracteristics that
could result in death, severe
injury, or property damage.

CCompact spare tire replacement
(if equipped)A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replaced compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed to mount a
regular size tire.
(Continued)•
Do not drive your vehicle with
too little or too much pressure in
your tires. This can lead to
uneven we ar and tire failure.
•
When replacing tires, never mix
radial and bias-ply tires on the
same car. You must replace all
tires (i ncluding the spare) if mov-
ing from radial to bias-ply tires.
•
It is best to replace all four tires at
the same time. If that is not possi-
ble, or necessary, then re place the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your veh icle’s handling.
•
Using tires and wheel other than
the recommended sizes could
cause unusual handling charac-
teristics an d poor vehicle con-
trol, resulting in a serious acci-
dent.
(Continued)

•
Wheels that do not meet
HYUNDAI's specifications may
fit poorly and result in damage to
the vehicle or u nusual handling
and poor vehicle control.
•
The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing ti res, all 4 tires
must use the same size original-
ly supplied with the vehicle.
Using tires of a differe nt size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregu -
larly. (if equipped)

WWheel replacement When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire tractionTire 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 con-
trol of the vehicle.Tire maintenance In addition to proper inflation, correct
wheel alignment helps decrease tire
wear. If you find a tire worn unevenly,
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 labelingThis information identifies and
describes the fundamental charac-
teristics 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 recall.1. Manufacturer or brand nameManufacturer or Brand name is
shown.
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
a bilities, handling characteristics,
ground clearance, body-to-tire
clearance, snow chain clearance,
spee dometer and odometer cali-
bration, headlight aim and bumper
height.

1.(#,204/3424-322. Tire size designation A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)P195/65R15 94HP - Applicable vehicle type (tires
marked with the prefix “P’’ are
intended for use on passenger
cars or light trucks; however, not
all tires have this marking).
195 - Tire width in millimeters.
65 - Aspect ratio. The tire’s chapter height as a percentage of its
width.
R - Tire construction code (Radial).
15 - Rim diameter in inches. 94 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the speed rating chart in this chapter
for additional information.
Wheel size designation Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:6.0JX156.0 - Rim width in inches.
J - Rim contour designation.

33. Checking tire life (TIN : Tire
Identification Number) Any tires that are over 6 years old,
based on the manufacturing date,
(including the spare tire) should be
replaced 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 num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.DOT : XXXX XXXX OOOOThe front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1618 represents
that the tire was produced in the 16th
week of 2018.
4. Tire ply composition and materi- alThe number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.5. Maximum permissible inflationpressureThis number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that tires
generally be replaced after six (6)
years of normal service. Heat
caused by hot climates or frequent
high loading conditions can accel-
erate the aging process. Failure
to follow this warning could cause
sudden tire failure, which could lead to a loss of control and an
accident inv olving serious injury or
death.

• Only steel wheel provided as a spare wheel with all variants of vehicle.
• Spare tire make can be from any tire manuafacturer i.e. Bridgestone/MRF/Apollo.
• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if colder temperatures are expect\b
ed soon. Tires typically lose 7 kPa (\f psi) for every 7°C (\f2°F) temperature drop. If extreme temperature variations
are expected, rec
heck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high\baltitude area above sea level. Thus, if you plan to drive a high\baltitude area, check the tire pressures in advance. If necessary, inflate them to a proper level (Air infla\b
tion per altitude: +\f0 kPa/\f km (+2.4 psi/\f mile).
