Front Rubbing - Tires, Suspension or Wheels?

Here is what I found. The wheels on the front right now are actually 15x6 with 3.375 back spacing. The rear are 15x9 with most likely 6.5 backspacing. I'm guessing on the back spacing by looking at what's available to purchase new (yes I know I could take the wheel off and measure, but I just haven't had a chance).

I went to Discount Tire today to get their input. He didn't actually measure anything except the wheels I already had and then made some recommendations. With that said, I thought I would post his recommendations and see what the consensus is here.

For the front, he recommended a 17x7 with a bs of 3-3.5" with a 225/45/17. I can get a TTII in a 17x7 with 3.5" bs.

For the rear, he recommended a 18x8 with a bs of 3.5-4" with a 275/40/18. I can get a TTII in a 18x8 with 3.75" bs.

Thoughts? The guy seemed to know what he was talking about, but since he didn't actually put a measuring stick to the car, I'm a little hesitant. If I order what they recommend and they don't fit, they'll have to take them back and get me the right size, but I don't want to go through that hassle if I don't have to.
