help with ross polo bike

Hello!
I have bought an old ross polo bike.
I need to put new tires on it.
Can anyone tell me which ISO tires to get, ISO 406, 419 or 451.

Thank you for your time and any help.

Jackie

I'm assuming the bike currently has tires on it?
If so, there's probably a size marking somewhere on the sidewalls, just like a car tire.
