Same old tire question

[Y2K4 STANG]

I will probably get blasted for asking, but, I cant find a solid answer.
1967 coupe - I want to go with a 16" American Racing Torque Thrust II.
What is the widest and tallest tire I can fit without suspension mods, and fender mods? Sorry for the same old question

im not sure but i say in the rear maybe a 275 widest, maybe a 255 up front.

dont hold this to me, a 65 has different setup then later years
