Widest front tires

There`s a ton of threads here that focus on the widest tire that will fit in the rear with stock wheelwells but hardly anything about the front. What is the widest tire you guys are running in the front? Rim size? Backspacing? I`m trying to emulate an F/60-15 on the front of my 68 Barracuda which seems to come out somewhere in the 235/60-15 range. Any input would be appreciated.
