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.
