Oh, wait, I just reread what you wrote. 245/45/17. So your tire is just plain too big period. Hasn't rubbed. Yet. That tire is more than an inch larger in diameter than the stock wheel/tire combination and is nearly 5% off of stock size. So your odometer, speedometer, and gearing are all going to be off. Not to mention your car is sitting an extra half inch in the air.
Oh, BTW, 7" is still not the recommended width for a 245/45/17. Minimum width for that tire is still 7.5, recommended is 8.0, maximum is 9.0. That's what Toyo, Pirelli, Yokohama, Fuzion, Bridgestone, and Goodyear all say. I seriously doubt Falken lost their minds and recommended a narrower rim.
