Help me choose a tire?

I did the trial and error on ours with some smaller used tires I have. It has new 235/60r14 in the front and they don't rub. I like the wide foot print look. I bought new 225/70r14 and did rub on turns so now I'm stuck with a pair of those. 255/60r15 on the back. I will be changing to 275/60 later, I have the room with an 8 1/4. I did do the 73 front disk conversion also and the rims are 14x6.75 ET mag with 3.75 backspacing.
