Yeah 18" is too big if you are concerned with performance. In order to maintain the same overall wheel diameter, really low profile tires are neccesary, which do not soak up as much of the force from hittting bumps as tires with taller sidwalls. I can't say that if you hit x pothole with y depth and z length then you will definately bend the rim. The best I can say is that they will bend if you hit a big enough bump/hole. It is impossible to say how large. Big rims will slow your car down because of rotating mass. People don't usually plus size rims more than 2". 16" is usually the best for the s13.

Um yeah, but nobody is gonna put a 225/35 on a 16" rim. As long as overall tire diameter stays the same, with larger rims, there is less sidewall, making it easier to damage the rims. Smaller rims require a larger sidewall to maintain a certain diameter.
