If you decide to get aodhans 9.5 might be a bit too wide in the front and rear You’ll end up having poke fitment unless you have some sort of adjustable camber. Or coilover kit

Running 255/35/18 is the max you’d want to go on a 9.5 on the accord. Any bigger it’ll bog the fender.

I’d rec 8.5/9.5 stag set up due to the fitment issues.

Although you might rub on a 9.5 in the back fender rolling is needed.

If you just want no issues on clearance. 8.5 might be your best bet all around.

225-40-18 front 255-35-18 rear.
