Schwalbe and Suomi Nokian are the big 2 in studded tires, there is no smaller than 35 wide tire in 700c
AFAIK.
Can I get by without studs or with my current tire?
as long as the rain is not a solid, IE Ice, then the hard case puncture resistant tire would be OK,
It may be a good idea to get a 2nd set of wheels so you leave the studded tires on them, **
rather than subject the bead to repeated removal and replacement.. when the forecast says it will be below 0C that night..
Yea 19 miles , I'd take the Bus . Otherwise, that is adding 4+ hours of riding to an 8 hour work day riding both ways in the dark.
** since it will be dark and the ride is going to be adding another un paid part time job..
that wheel set had better have a hub dynamo in the front wheel, and wired LED lights...
