"When he opened the present, he let out a whoop - it was exactly what he'd asked for."
Damage. Hole. Perished gasket. Incorrectly fitted. Corrosion.
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
What kind of noise and is it just one tire?
A lot of reasons.. more details would be needed in order to assess the cause.

A computer tower may make a surging noise rather than a constant humming noise if the case's screws are not properly tightened. Another reason for such a surging noise is the imminent failure of a fan.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
