atm focusing on 225/45/17 for the inspira; back burner on the 195/50/15 iswara (which is the first time i've tried ad08r)
no interest for Toyo/Nankang

gt radial/federal also on the sidelines as i have bridgestone/dunlop/hankook/kumho lined up to try (which may or may not happen, and will definitely take YEARS since my track only tires have very little wear )

225 is probably the max you can go on 7.5jj. Mine was aftermarket so not sure on stock size.

Can go with yokohama s drive,  or AE50, Michelin ps3, Bridgestone RE003. Budget wise may be out of your 400 per piece though.

235/45 can still use minimum 7.5jj rims but 225 or 215 look better.
If budget only max rm400, probably better just try GT Radial HPY or Falken Azenis FK453.
