All Season Tires
HYUNDAI 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
HYUNDAI 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, HYUNDAI 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;
otherwise, 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
maximum 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.
Radial-Ply Tires
Radial-ply tires provide improved
tread life, road hazard resistance
and smoother high speed ride. The
radial-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
combinations 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 follow 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.
WARNING
Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause loss
of vehicle control resulting in an
accident.

Low Aspect Ratio Tires
The aspect ratio is lower than 50 on
low aspect ratio tires.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than
a standard tire. Also low aspect
ratio tires tend to be wider and
consequently have a greater contact
patch with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
CAUTION
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of the
wheel and the tire itself is more
easily susceptible to damage. Use
caution when driving and follow the
guidelines below to help minimize
damage to the wheel and tire:
• When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.
• When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not damaged.
• If the tire is subjected to a severe
impact, have the tire and wheel
inspected by an authorized
HYUNDAI dealer.
• Inspect the tire condition and
pressure every 1,800 miles
(3,000km).
CAUTION
• It is not easy to recognize tire
damage with your own eyes. But
if there is the slightest hint of tire
damage, have the tire checked or
replaced because the tire damage
may cause air leakage from the
tire.
• If the tire is damaged by driving
on a rough road, off road, pothole,
manhole, or curb stone, it will not
be covered by the warranty.
