Brian, I would say 235 & 255 is the biggest you can get on a stock ride height unmodified wheel well '69. I have 255/60-15 BFG TA's on the back of my SS396 right now with no problems (except even they won't hook up), but I have had them on other 69's and had them slightly rub on the edge of wheel lip at inside top. Same with 235's on front, sometimes no rub (barely), sometimes rub just a litle. To be 100% safe I usually go 225's and 245's. Just my experience with 15+ '69's in the last 20 years. Good Luck!
