OP rule of thumb is dont go over 20% width. A 9.5" wheel can support a 289mm tire and be fine.

Stock suspension and with a iPhone and a level I got -0.9 front left, -0.5 front right, -2.1 rear left, -1.5 rear right. Fronts stick out but I need -3, -2 camber to pull them in and get a good track number. Fronts 9.5" +25 on 255/40 and rear is 10.5" +15 285/35.
