Tire hitting fender

I have 245 60 14's on 14x7 Indy slotted wheels on the rear of my cuda. I wanted to mount the same on the front but before I purchased another set of that size I mounted the rears on the front and noticed that the left front just nicked the lower portion of the front fender and the right side cleared by a safe margin. So I bought 235 60 14's on the front with the other 14x7 wheels.
PS This is an all original car that has been thoroughly abused so I know something is a little off. I actually measured across the top from right rear inner fender to left front rad support and vise versa and one side is about 3/16ths off. Which is remarkable.
