The TR is a very low weight 17x7 wheel, it will look more like a 16 possibly with the spoke design but make the brakes look bigger..., I would stick with a 205/45/17 tire for more sidewall support.
Wide tires on not real wide rims only help in acceleration, braking and looks, they can most often degrade the handling.
Skinny tires on really wide rims degrade everything but the looks for those that like the look, which I do not care for so they hurt everything.
Tires just a bit narrower than the wheels, a bit of stretch, will have the best handling feedback and often times grip in corners.
The 205/45/17 PS3 is pretty wide for it's specs but that is how tires are made, there is no true standard in measuring the width, they pretty much just call them what they want. I would like 7.5 or 8.0 for my PS3 tires but none are available in 4x100 unless custom. 4x108 some are but far to heavy.
If I could find some tires like the PS3 in a 205/55/15 or even up to a 225/50/15, etc....I would run 15x8 or 9" wheels to save more weight, I could get a set down to close to 30lbs!
