i don't believe i have any issues w/ rollover, but i do not have any experience w/ a wider wheel and same tire. i run 38psi front, and 46 psi rear. FYI: the eibach sportlines are soft as hell in the back, and the rear tires never get above warm. Any lower pressure in the front, and it does rollover the sidewall. the kuhmos have a triangle on the sidewall to let you know where the wear point should be, and i'm right on it at 38psi. i'll email you the pics when i get a chance.
