Not wheel alignment... but suspension geometry. I know that each suspension setup is tailored to a particular width of the tyre. The suspension can cope with increasing the rolling diameter, but when you increase the width, the camber which is stock at -1.0 I think, will exert added force on the edge of the wider tyres.

But I think 215 should be ok as Whiteline's site says it's usually when extremely wide tyres are used the handling becomes worse because of inappropriate camber.
