nobody asked the key question about offset. what is the offset on these rims??
If you have a sedan you get get away with 17x7 40 offset if you have a coupe I would go with a 42 offset. That's if you want to lower, if you don't want to lower 40 offset will be fine they will stick out even with the fender.

225/45/17 are ideal tires they give a nice ride although still a little stiffer than stock.
