Drive in suitable speed …….why?
The high speed will increase the temperature
specially in summer.
To prevent the damage of tire in the summer season

4. The causes of damage the tires
The causes of damage the tires
•Select not suitable environment tires
•select non suitable temperature calcification
Not suitable air pressure in the tire
No good maintenance for the tire
High temperature
High speed
High load
Driving in non suitable road

5. tire service
1- reach deep point on the tire ( replace on the tire)
2- vibration at the driving (need balance technical serves)
there are tree service for this
a- Tire balance
b-Wheel flange
c- bencher
