I currently have the stock wheels and my tires are 215/55/17. I am looking to change these. I have my eye on a set of rims that are 18 and tires 235/60/18. Any idea if I would have issues?

 

Yeah, bad idea; the new wheel and tire combo yields an overall diameter of nearly 3" greater than OEM. There is an extremely high likelihood the tires will rub like crazy; that and your speedometer and odometer will under report by over 10%.
