'70 olds cutlass, widest tire up front 15" rim ?

newbie here, just picked this up, hoping someone can help I want to go wide as possible up front, looking for a low level stance stock car oval track look,with wheels tucked nicely inside wheel well. The rear is tubbed and currently has a 31x16.5 tire on a 15x12"rim with a 5.5 backspace. I'd like the rear tires to fill the wheel well even more, I have at least 2"inside and outside to work with. I'm thinking 15x14 rim with diameter around 28". Hope the pic attaches

Why all the info on the rear tires when the thread title is asking about the front tires?

Welcome to the site, I fixed your picture. Nice ride. What size wheel are you running up front?

I've run 255/60-15s in the front on stock rims with zero offset.

I wasn't sure exactly what you were asking before.

I also have 245-60-15s on factory SSIII wheels, and have not had issues with rubbing. There seems to be plenty of clearance all around. Back in the 80s a tire shop inadvertently put one 255-60-15 on the left font and it rubbed slightly during turns. You may be able to get away with 255s depending upon your suspension setup - mine was factory original back then, so maybe sagging a bit.
