CARE
AND MAINTENANCE OF TYRES /TUBES
To
obtain maximum life and performance tyre/tube care and maintenance is
very important. For proper tyre/tube care & maintenance,we recommend
the following.
1.Proper
tyre mounting & De-mounting
-
For optimum radial advantage mount vehicle with full set of radials
at both axles and at
spare position. Mix use of bias and radial tyres on the
same vehicle is not recommended.
- Always use a new tube for a new tyre.
Tyres/tubes should be of the same brand.
- Always use a designated tube for the particular type and size of tyre
being used.
- Always mount tyres on correct sized rim. Rim should be free of dirt
& rust.
- Rim valve hole should be round and smooth.
- Clean tyre interiors before placing the tube inside.
- Lubricate tyre beads with mild soap solution before mounting and de-mounting.
- Before starting inflating the tyre, check whether the beads are seating
correctly on the rim seats.
- Never exceed 44 psi ( 3.0 kgf/cm2) to seat the beads. After beads
are seated adjust inflation pressure
to inflation pressure recommended by vehicle manufacturer.
2.Tyre Balancing.
-
An un-balance wheel may cause vibration to the vehicle. So it is recommended
to balance tyre-rim assembly if so vibrations are
felt, or after every 5000 Kms.
3.Tyre
Rotation
-
Rotate tyre positions as recommended, if an irregular wear is found
on any of the tyre or after every 5,000 kms.
The first rotation is important as it sets the stage for long and even
tyre wear.
4.Wheel
Alignment.
-
Always maintain proper wheel alignment.
5.Daily
tyre check
-
Every morning before starting vehicle check the exterior of your tyre.
If the damages exposing the ply cord and / or steel belt
is visible, remove the tyre and consult with a tyre specialist. Remove
stones or nails which is entrapped in the tread of the tyre.
6.Tyre
change
-
The tyre being used currently should be replaced with a new tyre when
the tread wear indicator
( 1.6mm height) is exposed.
- Inflation Pressure maintenance
- Always maintain inflation pressure recommended by vehicle manufacturer.
- Inflation pressure should be checked when the tyre is cold.
- Check inflation pressure every week and before long trips.
-Watch for air leakage. The valve core should be re-newed and lost valve
cap should be replaced.
-New tyre tend to expand during a certain initial period and increases
its volume. This decreases the inner
pressure so frequent checking is recommended up to 3000 kms.
-Keep the inflation pressure of the spare tyre 5 psi (0.3 kgf/cm2) higher
than the recommended pressure and before
using bring inflation pressure to the recommended pressure
level.
