I had same staggered set up as you i had 225 40 18\'s on the front occassionally rubbed arch liner on lock and 265 40\'s 18\'s on rear never touched. I lowered the car to fill the arches with tyres with about 10mm gap. I used to run 215 35 18\'s on an impreza and i would go down lower than a 40 now...awful over bumps.

In all honesty id go 17\'s next time cheaper tyres and better handling.

thought about it but it was a case of what ever came along first and the 18,s are more common

One of my customers runs that size but with proper tyre sizes , 245,35,18 front  and 265-275 35 18 ,  I just don\'t get stretched tyres unless some Vw thing , if you want it to work fit the right size tyres and set the car up correctly and it will be good , Toyo etc have wheel size tyre fittment charts on there sites , 17" do work well on fds probably better but you set the car up differently for 18" to 17"
