    What's your motivation to go 225? Given the choice I wouldn't want to give up the 60mm of rubber on the road, but I'm sure you've got your reasons...just curious.

    True.

    Could go to a 235 square setup on the 135's.

    More neutral handling, at least in theory. A little less unsprung weight, less rolling resistance, ability to rotate (tho not easily). Last but not least, makes the whole tire shebang a hundred bucks cheaper.

    In my recent research on square setups, the most often recommended size is 245/35/18s on the 8.5s, or 255/35/18 if you add negative camber.

    I'm not sure if you'll see an improvement with neutral handling with a 225 stretched on a 8.5" wheel. The only reason I could see doing 225s all around is cost savings. That not-so-common 255/35/18 is expensive. Otherwise, I would put the proper 255 back there. If you want to go square, 17x9 with 255/40/17 works well. The initial cost with wheels can be expensive but tire replacement would be considerably cheaper in the long run.

    225mm is not going to be "stretched" on an 8.5" wheel. 225mm is equal to about 8.9 inches.

    I think this idea.

    don't see the point other than to save money. i'm sure it would fit just fine.

    Still running the old Pilot Sports on the ragged edge. Dry grip is still excellent but they are incredibly loud. Will report back when I make the tire swap.
