DO'S AND DON’TS
For each vehicle, tyre of a particular size,
pattern and ply rating is recommended for
usage. Fit only recommended tyres.
The rim and wheel used must also be of the
recommended type and in a very good
condition.
Care must be taken while mounting the tyre on
the rim. Improper tools and careless handling
will not only damage the tyre but could result in
accidents causing serious injury.
It is recommended that with each new tyre, an
appropriate new tube and where applicable, a
new flap should be used.
The tyre has to be ensure with the right
inflation
as
recommended
by
the
manufacturer. Under-inflation and over-
inflation can seriously reduce the life of the tyre
and may even cause accidents due to
premature failures. The inflation pressure
should be checked at least once in a week
when the tyres are cold and have not run for
long.
The maximum load imposed on a tyre should
never exceed the maximum load carrying
capacity of the tyre.
Tyres rotation should be carried out as
recommended in the service schedule.
Driving on worn out tyres can be very
dangerous and can lead to serious accidents.
