Rotation as a routine preventive maintenance practice can reduce the typical irregular wear patterns that are found on different axles.
A few golden rules to follow when rotating.
Firstly, the tyres should be rotated so that they roll in the opposite direction (except in the case of unidirectional tyres). You can rotate between front or free-rolling and drive axles. It’s worth noting that a tyre should be rotated more frequently in the initial periods of wear. This is because there is a higher degree of tread squirm and irregular wear when the tread depth is greater.
METHODS OF ROTATE TYRES
The most common form of rotation is the cross rotation pattern.
This involves swapping tyres from one side of the vehicle to the other. Tyres on tandems are also swapped between axles
Another rotation pattern is called ‘move back’.
This is applicable to fleets that use very deep drive radials, like the Bridgestone M718/ M729.
This method can also be used for all-position tyres such as the G582. Once the drive tyres are worn down to a certain tread depth, they can be moved back to the trailer positions. The move back pattern can get many more useful miles out of the tyres.
IRREGULAR WEAR CAUSED BY MECHANICAL PROBLEMS OF VEHICLES.
If the irregular wear is caused by a mechanical defect such as a misalignment, loose bearing or suspension issue, then there is not much that can be done, other than rectifying the cause of the irregular wear.
