Not familiar with NJ snow events other than what makes the national news.
Up here in Seattle we don't usually get long periods of frozen roads. A day or two of slush, then it melts.
I got a set of all season tires put on the stock rims a couple weeks ago and put the stock tires in the bassement.

I wouldn't recommend the Michelin Low Rolling Resistance (LRR) tires that came with my car for driving in freezing conditions.
Take a look at your sidewalls. Some places, the 86 came stock with Bridgestone All Season tires.
Those may be slightly better for slippery driving.
If you have those and are still having problems, you might want to consider real snow tires.
