Welcome to NSXB! I can not help you with all these question but one of our many wheel experts will chime in soon.
I would recommend you get bigger rims, 17 or 18'' and anytime I mess with anything having to do with my tires I always get allignments done right away just to be safe. But again more people will chime in who know more about this then I do. Most ppl are sleeping right now.
