TYRE ROTATION AND INFLATION
TYRE ROTATION:
The purpose for rotating tyres is to achieve a more uniform wear for all tyres on a vehicle. Before rotating tyres, determine the cause of any unusual wear and correct any misalignment, imbalance, or other mechanical problems.
Otherwise it will cause: 1. Ride disturbing; 2. More noise; 3. Poor ride comfort; 4. Shorter of life span.
Note: it is suggested that tyres should be transposed as soon as the phenomena above mentioned are detected (especially the two front wheels).
The tyre transposition patterns are acceptable below. Please refer to your vehicle owner’s manual regarding tyre transposition advice.
TYRE INFLATION:
One of the most important aspects of tyre maintenance is proper inflation.
Sufficient inflation is needed to carry the load and avoid damage. Driving with improper inflation (particularly grossly under inflated or over inflated tyres) is dangerous and can cause critical damage or sudden failure of the tyre(s). Proper inflation should be maintained and check on at least weekly bases and before long distance drives.
Proper inflation should be maintained and checked at least once a week and before a long distance drive.
It is also advisable to take into account axle load and driving conditions when setting inflation pressure. Compensation for heavier loads can be made by increasing inflation pressure, but do not exceed maximum inflation for the tyre or maximum axle load.
In the space of just one month, a tyre can lose 10 pounds of air pressure.
It is important to check your air pressure regularly, to make sure your tyres are neither under nor over inflated.
Under-inflation
Is the worst enemy your tyre can have. It causes increased treadwear on the outside edges (or shoulders)of the tyre. It also generates excessive heat, which reduces tyre durability. Finally it reduces your fuel economy by increasing rolling resistance-soft tyres make your vehicle work harder.
Over-inflation
Is also detrimental to the tyre. Too much air pressure causes the center of the tread to bear the majority of the truck’s weight, which leads to faster deterioration and uneven wear. Any kind of uneven wear will shorten the lifespan of your tyres
