Hi, i was wondering, what's the biggest tires i can fit on my car? Because either i'm getting some nicer 17" and putting my summer tires or, but i'm really looking into some pegasus 18" wheels. My question though, would 245/40/18 fit on my car? If so, would it fit if it's dropped 1" all around?

I was looking at some 19" wheels, but that's getting to big imo. I was either thinking 235/40-45/18 or 245/35-40/18 but 35 of sidewall probably rides like crap... Personally i'd prefer 245/40/18 if possible with a drop kit on.

Thanks for the help.
