WHEELS AND TYRES

D. TYRE VIBRATION DIAGNOSIS

1. Visually inspect tyres, wheels/rims, and vehicle

for uneven wear, damaged wheels/rims, or

vehicle component damage. Replace or adjust

as required. Check wheel mounting to hub,

adjust torque of wheel bolt to the specified

value.

2. Make sure that tyres are inflated with specified

pressure and suspension is working correctly.

3. Check for proper tyre mounting on the

wheel/rim. The tyre fitting line should be

concentric with the rim flange. The yellow or

red mark on the tyre should be oriented to the

rim correctly.

(Refer Matched Tyres and Wheel

Rims given in this section)

4. Test drive vehicle on a smooth road surface

and diagnose symptoms.

5. Check tyre wheel/rim assembly balance.

Adjust as required. If unable to balance,

completely deflate tyre, unseat tyre beads, and

rotate tyre 180 degrees on the wheel/rim.

Rebalance tyre and wheel/rim assembly and

test drive vehicle.

6. If vibration is not eliminated, measure tyre and

wheel/rim assembly for excessive lateral or

radial run out. Replace as required. Rebalance

tyre and wheel/rim assembly and test drive

vehicle.
