08 Cobal SS TC, I want 235/40/r18 all around.
 

Does anyone have any experience with putting 235s on the stock ss 18 inch rims. I was planning on getting new rims that are 18x9.5 but that will happen at a later date. For now I need winters and summers. Let me know if guys have had any problems with fitment or rubbing.

This is how low my car is for a visual representation.

What suspension mods do you have?

that tire will fit fine stock hight and as low as peddlers or Powell will go. Not sure about coil overs.
If you go that wide with the rims however who knows. They are gonna be over an inch wider than the tires.

I ran 235/40 on a stock width wheel without rubbing. I was on Powell yyz v1springs .

The 235 only adds ~1\2 inch in overall diameter and less than a half inch of width over the 225.
