Dark side (car tire) size?

[rhodyrider401]

I know it must be here somewhere (but I am apparently not very good at searching this forum), so can someone tell me, point me to a link about what size care tire is best for a 2002 Nomad 1500FI.
Thanks!
I 'think' I would like one that is as close to the same size as stock, but am open to being talked into a different size if there are benefits.
I was also thinking that skinnier would be better, but am interested in what others think.
Finally, any brands that people like/dislike? What makes a car tire, good on a bike?
Thanks!
