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 the 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.

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

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

movement. In order to complete such tasks, a tire must be structured to be a resilient 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

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.
