REPAIRING TYRES
Repairing a Tyre :
Mark the tyre position (if original
colour dot mark is not visible) with
respect to valve stem hole to ensure
that the tyre is refitted in the original
location on the wheel rim.
Ensure that balancing weights are
not disturbed during removal of tyres.
Check the balance weight prior to the
removal of the tyre. If found loose,
mark its location on the rim & refit
properly.
Balance the wheel after every
dismantling and assembly of tyre on
the wheel rim if required.
While fitting wheels on the vehicle
ensure that wheel pins are free from
dust, scratches, dirt, dents, etc.
NOTICE
Do not apply any oil on the wheel
pins. Wipe off the oil if present.
Special care for tubeless tyres
1. While removing tyre from wheel
rim and mounting it back on
wheel rim, take precautions not
to damage tyre bead. Use tyre
removal
machines. Damage or cut on tyre
bead may cause gradual loss of
air and deflation of tyre.
2. Do not scratch inside of tubeless
tyre with metallic or sharp object.
Tubeless tyres are coated with
impermeable layer of rubber
from inside which holds the air
and assembly
MAINTENANCE
inside the tyre. Removal of this
layer due to scratching may
cause gradual loss of air and
deflation.
3. If wheel rim gets damaged in
service, get the wheel rim
repaired/replaced immediately.
Running the vehicle with
damaged rim may cause
deflation of tyre and subsequent
dislodging of tyre from rim.
4. Maintain recommended inflation
pressure. Over-inflation, in
particular, may cause puncture
or bursting of tyre.
NOTICE
Life and wear pattern of tyres
depends on various parameters
like tyre pressure,
alignment, wheel balancing, tyre
rotation, etc. It also largely
depends on vehicle speed, load
carried, usage, driving habits,
road conditions, tyre quality, etc.
In case fault is suspected to be
due to poor quality of tyres, the
same may be taken up with
concerned tyre manufacturer.
