Okay so i have a 79 malibu with the stock 14x7 rally's, what is the widest tire i can fit on the back but yet have the wall height make the car look good? i don't know what the backspace is on these rims, but im sure someone knows it. They are the original rims. I heard that a 235 is the safest wide tire to put on the 7 inch rim, but will the wide tire clear the shock and eveything inside the rim? need help soon, would appreciate an answer by tuesday so i can go out and look for a pair.
