2) Speedometer Gauge
The speedometer indicates the vehicle speed by calculating the signals from the rear left and rear
right wheel speed sensors through ABS or ESP unit. (For the vehicle without ABS or ESP, the
signals are received from the EMS)
If the speedometer gauge vibrates, stops at a certain range or makes an abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be occured when th
e
tire has uneven wear, different tire inflation pressures or different tire specifications.
Perform the speedometer test regarding the tolerance as described. However, it is not similar
simple work in field due to lack of measuring conditions such as test equipment and preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer by
using a tester.
Check if the speedometer pointer is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer. 1.

The difference between both sides should
be within 0.6 kg.Park the vehicle on a paved and flat
ground and place the front wheels at
straight ahead direction.
Start the engine and let it run around 1,000
rpm.

Measure the dial runout and lateral
runout on both the inboard and
outboard rim flanges. - Tire inflation pressure -
Check the tire inflation pressure by
inspecting the tread width. -
Specified value 2.66 mm
Wheel runout
If wheel runout or tire runout is excessive,
it could result in abnormal wear of the tire.
Measure the runout with a dial gauge. 4.
Measure free radial runout on the tire
tread. -
Specified value 2.03 mm
If any measurement exceeds the above
specifications, replace the applicable
tires or wheels -Tire inflation pressure 3.
Specified value 32 psi
Maintaining the specified tire ressure is
essential for comfortable riding, driving
safety, and long tire life. Incorrect inflation
pressures will increase tire wear and will
impair safety, vehicle handling,
comfortable driving and fuel economy.
Always make sure that the tire inflation
pressure is correct.

1. OVERVIEW
A radial tire uses a cord angle of 90 degrees. That is, the cord material runs in a radial or direct
line from one bead to the other across the tread. In addition, a radial tire has a belt overwrap
under the tread surface to provide greater structural stability. The belt overwrap of a radial tire
distortion while the radial structure enables high speed driving.
Tire supports the weight of the vehicle, reduces the impact from the road and at the same time,
transmits the power to propel, brake and steer on the road. It also functions to maintain a

vessel of air.
There is wear limit mark on the tire, which protrudes as a strip shape located approximately 1.6
mm from the groove bottom. This wear limit mark is not seen from the outside so there is
additional "▲" mark on the shoulder to let the driver find the wear mark easily. To measure the tire
groove depth, measure at any point other than the point which has a wear limit mark.
The tire is worn unevenly according to the driver's driving habit, improper servicing, low tire
inflation pressure, changed tire location, etc.

Structure of Tire ▶
Tread
This thick layer of rubber provides the interface between the tire and the road. Wear-resistant
rubber is used to protect the carcass and belt against fractures and impacts and to deliver a long
driving life.
Shoulder
Located between the tread and sidewall, the shoulder rubber is the thickest so that the design
must allow for the easy diffusion of heat generated within the tire while driving.
Sidewall
The part between the shoulder and bead, the flexible sidewall protects the carcass and enhances
the ride. A tire’s ty
pe, size, structure, pattern, manufacturing company, product name and various
characters are indicated here.
Bead
The bead attaches the tire to the rim and wraps the end of the cord fabric. Comprised of the
bead wire, core, flipper and other parts, the bead is generally designed to be slightly tight around
the rim so that in the case of a sudden drop in inflation pressure, the tire will not fall off the rim.
Carcass
As the most important framework of a tire, the entire inner layer of cord fabric is called the
carcass. The carcass acts to support air pressure, vertical load and absorb shocks.
