The tires are 275/60/15 on Cragar 15" x 10" with 6" backspace. I do not have a "A" body rearend. I think its from a "B" body, much wider. The tires set about a 1/2" off the spring which should be ok. The fronts are 205/60/15 on Cragar 6" x 15" with 3" backspace. I wish I would have gone with a little taller tire on the front. All tires are BF Goodrich T/A
