The standard wheels are 17x7 size, 4x108 pcd, 52.5 offset.
Obviously the pcd has to stay the same, if sticking with 17" rims you can either go with more 7" ones with about a 42 offset which will bring the rims out 10mm from the standard ones ... remember you dont have that much space available on the front before the wheels will stick out too far ... only about 10mm, on the rear of course you have heaps of room, stick with 205/40R17 tyres as well ... 215/40R17 will not only stick out too far but wont fit the 7" rim properly (if at all!).
With a 17x7.5 rim you will need to bring the offset back to something like 45 and install 215/40R17 tyres ... this will bring the wheels further out by about 12mm from standard.
This is a good site to play with all the different wheel, tyre and offset sizes.
