Good size rims???

[GSXMatt]

I'm probably going to be running 17x8.5 with a pretty decent drop, the only question is, I dont know what tires would fit that? Also I don't know if it should be +25mm or +50mm? Could someone clarify a little bit?

I really like the Bridgestone Potenzas, I think they look sick and they look like they would grip like no other.

I'm also not sure what the tire dimensions should be, I want a little bit of a lower profile then most 17s, I always see like 50/55 and I think on a pretty decent drop with a smaller profile like 40-35? Is that too little?

I'm a tire/wheel n00b for sure.
