Goonz12 - It will ultimately all depend on the wheels, tires and your car. It's been shown (I know it's in the offset FAQ) that even within the same model year, there are differences. Just because one person does not rub with his car does not mean you won't.
An example that I always use:
Suneil (ssmumich00) has said that he rubbed when he had 215/45 17's. I had the exact same wheel/tire combo and even with a car load of friends never rubbed.
I currently run 235/40 17's and rubbed ONCE going over a really bad dip in the road while I had other people in the car. That was the only time I've ever rubbed and I bet I can go with 245's. No spacers or rolling of fenders.
