1.Wheel and Tyre.
Don’t use weld, heating or blast to repair any wheels. All the
spoiled wheels should rereplaced.
Bolts.
Any spoiled bolts should be replaced.
Build-up Wheel and Tyre
Tyres and wheels are built-up from factory. Tyre and wheel
are fixed as a unit when doing balance examination. The tyre and
the wheel are marked with paint to avoid the spoilage of the
dynamic balance. Align the tyre well with paint mark when fixing
the tyre.
Before removing the tyre, draw a line on the tyre and the
wheel in case of uncertainty about the paint mark. And it is necessary for insuring the right
position.
Tyre-Pressure.
For all types of tyres, their advised pressures are fixed through accurate calculation in
order to obtain satisfied operation, stability, steering, tread wear, life span and cracks.
Tyre pressure, when the tyre is cool(three hours after parking or less than 1.6km
driving).They are supposed to be checked once in a month or before any long journey. Adjust
the tyre pressure according to the tag in the vehiecl-door 8kpa when the tyre is hot.
After parking, don’t deflate the tyre or reduce the tyre.
Higher pressure than advised may cause:
1.Hard-driving and reduced comfort.
2.Tyre crack ,spoilage of tyre case or even burst of the tyre.
3.Accelerate the wear of the central tread of the tyre.
Different tyre pressure in the same axle can cause:
1.Odds in brake.
2.Steering deviation.
3.Reduction in operation.
4.Deviation when accelerating.
Cover the valve to avoid dust and water.
Lower pressure than the advised pressure can cause:
1. Tyres make noise as turning.
2. Hard to turn.
3.Accelerate the wear degree of the tread unequally.
4.It may crack te rim.
5.Spoilage of the tyre cord.
6.High temperature of the tyre.
7.Reduction in operation.
8.Increase in petrol consumption.
Tyre Introduction.
Refer to the instructions which is in the right door of the vehiecle.
It listed the maximum loading , size and pressure of the tyre.
Transposition of the tyres.
In order to make the tyres similar wear degree, transpose the
tyres following the right illustration. Transposition the tyres after
the first mileage of 10.000kms. Then transpose the tyres for every
