If its superior handling, safety and streetability you favor above all, then the lower cost of a car tire (it's only redeeming feature in my book) is 100% irrelevant and it's a motorcycle tire all the way, regardless of some of the cockamamie arguments put forth by Darksiders.
The best rear meats for a stock rim are The B'stone Exedra Max, Avon's Cobra and the OEM Metzeler, in that order, IMHO. The B'stone is about 1/2" taller than the stock sized tire, which actually provides a slight improvement the bikes geometry and it is a higher endurance tire than the others, so it should give you some additional miles vs. the others.
