Multiple resistors in series to match the expected voltage spike?
The problem with that method, is that if the voltage spikes, are very high frequency, it is more the stray capacitance (and inductance etc), and specific PCB layout etc, which effect how the voltage spike is transiently split amongst the resistors.
So very briefly, one (or more) of the resistors, may see MOST of the voltage transient, EXCEEDING the datasheet specification, and hence potentially gradually breaking down the insulating properties of the resistor.
There are some very good article(s) about this, on the internet. Offhand, I've forgotten where a really good one was, that I read many years ago.
tl;dr
Best to use a properly voltage rated resistor, rather than try to share the voltage amongst multiple resistors which may be unreliable or even unsafe in the longer term.
EDIT:
For similar reasons. This is why on some relatively high voltage PCB circuits, slots are cut out in the PCB, in appropriate places. To stop the high voltages/transients gradually breaking down the insulating properties of the PCB.
