REASONS FOR TYRE WEAR EXPLAINED !!

The treads of tyre wear varies in relation to the type of road surface, the number of curves, the amount of traffic, the temperature and the driving habits of the driver. 

Abnormal wear can be accounted for by such conditions as incorrect-pressure, faulty wheel alignment, faulty brake adjustment and over loading. The probable causes of tyre wear and their remidies are discussed below:

Probable causes of tyre wear

1. Over inflation: The wear in the centre of the tyre tread is increased by excessive internal pressure. 

The air pressure also causes the increase cord stresses which reduce the tyre life. Apart from this the riding comfort is affected and more ear noises e.f. rattles or squaks become accentuated.

2. Under-inflation : Under inflation causes the side-walls of the tyre to bend sharply as the wheel revolves, so that the line the cord breaks and utimately the tyre blows out.

3. Front-wheel-Misalignment : This is a frequent cause of rapid tyre wear. Despite increased steering drag, the irregular tread wear will occur, which will slow feathered edges with a ‘filed’ appearance caused by the constant side grinding effect.

4. Rear-wheel Misalignment : The rear wheels will not be parallel to the centre line of the chassis if chassis frame is distorted. Serious tyre wear will take place due to sideway drag.

5. Defective wheels : wheels can be distorted due to accidents or kerb impact and therefore do not rotate truly on their hubs. As a result excessive tyre wear may be caused. Wheel rims more than 1.5 m.m out of true should be discarded.

6. Excessive Speeds : The tread wear increases fairly with the car speed. Other factors affecting tyre wear are condition of -road surface, curves, temperatures, unbalanced wheels and tyres, neglect of small cuts and oil or grease on the corners.

7.  Excessive Wheel Camber : It results in excessive side wear on the treads. This may be due to incorrect adjustment or some severe accident: which leads to excessive wear in the king-pins and suspension bearings.

8.   Flats on Tyres: Flats are caused by violent braking, resulting in wheels locking, so that the tyres dragged over the road without turning.
