3.3TT Square 19” setup what would you do?

[Clearly Canadian]

Not really planning to action this right now but thought I’d ask out of curiosity. If I wanted to go with a square 19” setup for the wheels/tires, what wheel and tire size would you recommend I go with?

@CaliSting said 18x10". But I'm still finding out if that is optimal or a practical maximum. On this thread: Widest Tires on AWD?
