Upsizing my wheels from stock 19in(2018 ct6) to the 20x8.5 2nd gen ct6 wheels(Vogue)what tire size are yall using for the setup?

1st pic is my ct6/2nd are the OEM wheels I want to purchase

So right now my tire profile is 245/35/19. Now if I want to keep the wheel gap for 20 inch wheels what tire profile should I go with?
