Explanation

Explanation text category D / driving tests drpciv:
The premature wear of the front wheel tires is caused by the incorrect adjustment of the toe angle.
If the pressure is too high, the tire wears on the crest of the tread.
If the pressure is too low, the tire wears on the edges (in the bead area), it heats up, the cord threads can come apart, thus the tire becomes unusable and must be replaced.
Local or uneven wear of a tire 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 the misalignment of the wheels.
Excessive heating of the tires occurs at very low pressures or under overload.
Correct answer: C
