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.
