It also largely depends on car
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.
Tyre Rotation :
To help increase tyre life and distribute
wear more evenly you should have
tyres rotated at specified intervals or
earlier depending on the operation of
vehicle.
The illustrations shows how to rotate
tyres when normal spare wheel is
included in tyre rotation.
Wheel alignment :
Incorrect wheel alignment causes
excessive and uneven tyre wear.
Check wheel alignment at specified
intervals. Wheel alignment values are
given below :
Front Rear
Caster 3.1’ + 45’ ---
Camber 30’ + 30’ -52’ + 1
0
Toe in - 12’ + 15’
Toe Out 0’ to -13’ -
Check and maintain tyre pressure
periodically to obtain longer tyre life.
Wheel Balancing :
Wheels of your vehicle are balanced
for better ride comfort and longer tyre
life. Balancing needs to be done
whenever tyre is removed from rim.
1. Permissible imbalance for tyre with
rim = 250 gm-cm max.
2. Total balance weight should be
within 140 gms on each side.
3. Relocate the tyre if the weight
required to balance is more than
140 gm.
4. Balance weights are available from
10 gms to 140 gms in steps of
every 10 gms and from 15 gms to
135 gms in steps of every 10 gms.
5. Do not use more than one balance
weight on one side.
