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,
their sidewall is a little stiffer than a
standard tire. Also low aspect ratio
tires tend to be wider and conse-
quently have a greater contact patch
with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
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 cau-
tion when driving and follow the
guidelines below to help minimize
damage to the wheel and tire:
- When driving on a rough road oroff road, drive cautiously because
tires and wheels may be dam-
aged. 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 dam-
aged.
- If the tire is subjected to a severe impact, have the tire and wheel
inspected by an authorized retail-
er of Genesis Branded products.
- Inspect the tire condition and pres- sure every 1,800 miles (3,000km).
NOTICE
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.

Specifications & Consumer information
* Normal load : Up to 3 persons
Information
• It is permissible to add 3 psi to the standard tire pressure specification if cold-er temperatures are expected soon. Tires typically loose 1 psi (7 kPa) for every
12°F temperature drop. If extreme temperature variations are expected,
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: +2.4psi/1mile )
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.
