Which of these factors may cause rapid wear of the tires on the front wheels of a passenger car?
aSlight overload of the vehic's lfront axle.
bIncorrect toe-in.
cUneven road surface.
Why?
Incorrect toe alignment makes the front tyres scrub sideways as they roll. This causes faster and often uneven tread wear. A light axle load is not a typical cause of this wear, and an uneven road may damage tyres but does not explain the scrubbing caused by incorrect alignment. The photograph shows tyre tread, but the image alone cannot establish the cause of its wear.
