Wheel size under a 67 Valiant

[Nordstahl]

Hi, I have checked the Forum for hours...but I am not sure.
What wheel and tire size will fit under a 67 Valiant? Front and rear?
Try to buy 7x15 225/60 front and 7x15 234/60 rear.

I have 245/40-18 and 255/40-18 respectively, if that helps.
So a 235 should fit depending on wheel backspace, rear end width, etc.
