CLK 225 with 265 19" helppp




I read ALL the tire thread concerning CLKs and tires
One question is not answered really.
(I know it fits but...)
Can I use this combo : 225/35-19 with 265/30-19
if not why?
Extra info if needed: (F8.5 ET30 / R9.5 ET35) with PSS9 installed already
CLK AMG
I can't use 235 in the front
the PSS9 are too close to the tirethank you
