Staggered wheels with Square set of tires

[514.X5]

So My tire are almost finish so looking in getting a new set.

I am currently running a set of style staggered style 87 wheels (9.5 inch in front ET 45 and 10.5 inch in the rear ET 30) with the classic 275/40/20 in front and 315/35/20 in the rear also with 20mm spacer in front and 25 in the rear.

This E70 is my daily. Would most likely keep the style 87 but would also like to get the option to rotate tire on all for corners for longevity purposes without sacrificing the actual handling the current setup offers.

Anyone ever tried putting some 295/45/20 on a staggered setup? I feel like the 1'' difference from 9.5 to 10.5 is negligible, or am I wrong?

I have already seen some members running 295/45/19 on a square setup.

Anyone with some input?

Cheers
