If your rear tires rub while cornering, you've got bushings issues. Probably worn out & no longer fit tight, allowing things to move in the wrong direction.

I think he means he took the 265/50s off rear and tried them on the front.
14" or 15" rim? the sticker on my car says 205/70r14.
I've got 235/60r14s on the front of my 82 trans am with no problems, probably could go bigger but never tried.

I have 245's 65 15's on my 91 Formula with the 82 to 84 Stock 15" Turbocast wheels...
No rubbing, fills up wells nice and better traction since it's wider than factory...

I had 245s on the front and they rubbed on the brakelines. I went to 235s and they fit perfect.
