I finally found a set of rims that I really like and they are 18x9 Chrome Deep Dish Bullitts.

I need help with some tire issues though. I would like to see about running 295-305's in the back, but will they fit? As I also need some measurements for the front as well, so what would I run in the front. The tire I am looking at is currently not out yet but I'm pretty sure this is what I want to get...

But I'm not knowledgable with the Tire Sizes, and thats what I need help with. And if someone could also help explain to me why, these tires could, or could not be good for my car that would be great. Then last, will my stock brakes be okay with this combo? Thanks
