Can I do anything to these casters (on my parsons dining room chairs) to make them safe on solid oak hardwood floors? Maybe adding some sort of a rubber ring to the raised tread or even covering them completely so they don't roll at all?
(btw…removing them is not an option.)
I am also considering trying out this on the very remote off chance it could work on my type casters: https://www.amazon.com/gp/product/B004SOJIZC/ref=ox_sc_act_title_7?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

You might like "caster cups"
You can get them in a variety of colours, sizes and materials including transparent plastic.
For chairs that need to be slid in and out from under a table, you might need a type of caster cup specifically intended for that purpose
- From advertisement for "MagiGLIDE CASTOR CUP 4 PACK". I have not tried this and don't know if it is suitable for the intended use or whether the claims are justified.
Castor cups are usually cheap - it doesn't hurt to try them on one chair. You don't lose much if they turn out to be unsuitable.
