front wheel tire clearances?

[volcanocar]

im just curious as to what the max width for a wheel/tire combo may be on the stock front end of a 70 cuda?
im not worried about the rear because i have more room than i will ever use.

i want to go for a trans-am look with a real low stance and as wide of a front tire as i can run with out rubbing or hurting anything.

i want to use the 15" daytona style wheels if that helps any.

let me know what your thoughts are thanks

any ideas? what are the sizes that some of you guys are running up front? right now the car just has skinny 5 inch tires upfront.

My friend Mitch is running 255/60/15 front, 275/60/15 rear. he has rolled the front fender lip, he has road raced his Challenger for years.
this is his street size.
