That sounds good to me except rears should be 245/35... but it really depends on how low you are going.
Sidenote, i read somewhere on CL that 245/35 and 265/30 stretches very similarly on 10.5.

I run 235/35/19 on megans and tucking tire with a more conservative wheel. Even with fender tab relocation and shaving the liner, the metal eats away my tires. You will have limitations if you go 235. For 9.5, the best should be 225/35/19. That is the setup everyone uses. Tire brand also matters.

How about 255/30/19's rears.. I'm trying to be under 3% rolling diameter.. if i go 245/35 its above tht. 265/30 is fine still looking lil lower to stretch them more..

Oh yeah sorry you were AWD.

I would like to think that 255 shouldn't be an issue since its only a 4.3% stretch. 30 side wall is noticeably different than 35 but you are stretching 6.7% or so in the front with 225s. I'm sure some expert can chime in on this.
