Depends on the offset. Do your homework. 
You'll probably need lower profile tires, as the diameters will be larger than stock. Also I'm not sure that 235 width tires will fit in the front. The stock sport wheels are 225/45R17. The rears can fit 245/40R17, so you have a much better chance there.
Then you'd have to worry about clearing the brakes, which you won't know unless you physically test fit, even if the offsets are correct.

You want to put 235/55/19 tires on your car.
235 = tire width when mounted
55 = this is the aspect ratio (think of it as "thickness" of the tire sidewall)
19 = wheel diameter (you would need a 19" wheel to fit a 19" tire)
If you want those tires, then buy a 19" wheel.
