The
main factors which affect tyre performance and consequently
their life
• Tyre inflation
• Vehicle
maintenance
• Manner
of driving
• Miscellaneous
factors (heat, Position in which tyre fitted, road conditions, Seasons)
Inflation
pressure:
Tyre
Inflation:
• This
depends upon tyre
size, tyre
type,speed and load
• The
Inflation pressure are recommended by the vehicle manufacturer
Inflation:
• Under inflation
• Over inflation
• Proper inflation
Under
Inflation:
Under Inflation causes the following
defects:
• Uneven
tread wear, more wear at the tyre sides
• Lack
of directional stability
• Increased
rolling resistance leading to increased fuel consumption
• Excessive
flexing of wall
Over
Inflation:
Over
inflation causes the following defects:
• Reduced
tread contact area with the road surface
• This
results in rapid wear in the tread at the centre
• Reduced
tyre
grip
• Reduced impact resistance
• Increased vibration resulting in
uncomfortable ride
• Increased stresses may cause tread
separation and cracks in the side walls
Proper Inflation:
• The
amount of pressure will be exact amount , required for good driving
