WHEELS AND TYRES 9 FORM OF WEAR MAJOR CAUSES PATTERN In the case of edge of the lugs wears quickly, so the tread takes on the form of saw teeth When lug tyres are fitted on the front wheels the dominant force working on them is the braking force, making this sort of wear liable to occur. This is an inherent characteristic of lug tyres when overloaded or under inflated. When such wear occurs, the direction of rotation of the tyre should be changed. This can be done by refitting the tyre in the same rim such that the earlier inside sidewall is now outside sidewall. Do not include the tyre in rotation till the wear normalizes.
