I also just switched to the Firestone Indy 500's yesterday. I like the way they handle and the look of the white letters (I was not sure on how they would look but am very happy with it)
I got the 225/70/15's, I didn't want any rub problems and also did not want a wider tire for stone spray back on the rear quarters.

I agree with Gunslinger, they fit fine.
You will be happy with the tire.

I know the voices aren't real, but they have some pretty cool ideas...

I am not sure why everyone goes with 255/60.
I tried to stay closer to the original size on my 1971. Last time I changed tires, I went with 235/70R15. They rubbed on the front. I kept this size on the rear but stepped back to 225/70 on the front.
Also, I must be the only one to drive on four PV41 from Firestone. This is a tire specially made for the police with the appropriate Speed rating for the car. I have been very happy with this choice.

The 225/60-15 is the same outer diameter as the original F 70-15. Almost exact. The 225/70-15 are actually a little larger around.
