Passenger Tyre Information
The general unavoidable factors that affect tyre life are: seasonal and climatic conditions, road's surface, route and natural wear. However, tyre wear often results from incorrect inflation pressures, incorrect tyre fitment, poor maintenance and driving style. These conditions are avoidable.
Factors such as high speed driving, rapid cornering, sudden braking and rapid acceleration are all major contributors to increasing tyre wear.
Inflation pressures and load
These criteria affect the flexing or deflection of the tyre's sidewall. As the speed of the vehicle increases, so does the frequency of the sidewall deflection, which in turn causes an increase in the heat generated by that deflection. Tyre failure will almost always result if this is allowed to continue for too long.
The inflation pressure also influences the way in which the tread makes contact with the ground, and the relationship between the tyre and the rim. Both these factors can increase uneven tyre wear due to the tread not meeting the surface of the road across its full area.
It is important to fit the tyre best suited to the work being performed by the vehicle. This becomes more important in the trucking and commercial industry. Tyres with lug-type tread patterns will wear more quickly on tarred roads at high speeds than tyres with tread patterns better suited to on-road work.
Fitting a tyre that is either too wide or too narrow for a particular rim will cause the tyre to behave in a way in which it was not designed. A phenomenon known as rollover occurs when the tyre is too wide for the rim.
Checking inflation pressures, at least twice a month, is the best way to ensure tyre inflation problems are avoided.
Wheel alignment and suspension settings should be checked between ten and twenty thousand kilometres or when one suspects that a pothole or bad bump might have caused a change to these settings.
Abnormal tyre wear
Mechanical irregularities such as incorrect or excessive suspension settings, incorrect wheel alignment, excessive wear in suspension components and faulty steering or brake system are all likely to cause uneven or rapid tread wear.
Of these factors, those that cause incorrect toe angles are responsible for the most accelerated mechanical wear.
