Explanation

Explanation text category C / driving questionnaires drpciv:

The premature wear of the front wheels’ tyres is caused by the incorrect adjustment of the convergence angle.

If the pressure is too high, the tyre wears out on the crest of the tread band.

If the pressure is too low, the tyre wears out on the edges (in the bead area), it heats up, the cord threads can come apart, thus the tyre becomes unusable and must be replaced.

Local or uneven wear of a tyre occurs when the motor vehicle is overloaded or when the brake drum becomes oval or the wheels are unbalanced.

Wear on one of the edges occurs due to misalignment of the wheels’ geometry.

Excessive heating of the tyres occurs at very low pressures or at overload.

Correct answer: C
