84 GT 5.0 Tire Size
I have a just purchased1984 GT 5.0 that has the original Michelin 220/55 R 390 (TRX Wheels 4 lugs) which I cannot locate for any resaonable price. It appears that I should change the wheels and then move to a more standard tire size. I am trying to determine the maximum tire size that will not rub or require modification to the car. My goals is to get the following size for the car 245/40 -17 or even a 255/40 17. The wheel size would be 17"x8".
I have been told the maximum size that will fit is 225/60 15.
Any advice is welcome.
