What is the max height tire size for stock RX330?

[Longarch2]

I wish to stay with the stock suspension and stock wheels for now but was wandering what the maximum tire height I could achieve above the factory 235/55R18's (28.2H x 9.3W) and not experience strut or inner fender rub. I'm not worried about the speedometer reading incorrectly.

Tire sizes considered:

235/70R18 (31.0H x 9.3W)

245/65R18 (31.5H x 9.6W)

235/65R18 (30.0H x 9.3W)

245/60R18 (29.6H x 9.6W)

235/60R18 (29.1H x 9.3W)

245/55R18 (28.6H x 9.6W)
