Ben, again, remember that rubbing the struts may not be cured with spacers. The tires may be too tall and spacing them out 5-10mm sideways might not cure the problem, as they could still rub on the tops of the tire. Just be prepared for some trial and error. We have crappy roads here in Toronto and for the most part my 215/35s do just fine - but I have to watch out for big holes and bumps all the time.
Are the wheels you're putting on the same as the ones I have? I'll tell you one thing - they're hella strong. The rims are still completely straight while I've gotten a bulge in the sidewall of one of my tires last year from a huge bump on the road.
