Having trouble deciding between these two wheel sizes, any thoughts, concerns or suggestions?

4- 18x10+25 with 275/40/18
4- 18x9.5+15 with 265/35/18

Im a huge fan of matched front and rears, I did the staggered bit for a while and now Im over it.

-Going from stock to the 18x10+25 im looking at 20mm closer towards the strut and 30mm towards the lip.
-Going from stock to the 18x9.5+15 im looking at 4mm closer towards the strut and 34mm towards the lip.

In respect to each other, the 10+25 width will be 16mm towards the strut and 4mm inward towards the lip, so more recessed than the 9.5+15 and the 9.5+15 has more strut clearance.

 

here's a picture of my last setup, its a 18x10+25 wheel mounted in the front, no tire though, I might have to find a used one just for clearance purposes:



its pretty tight on the inside, i wish I knew how it would fit worse case with a 275/40 or 275/35, especially at full lft/rt lock. It also appeared to not really extend past the fender, hard to guess without a tire still.
