What size tires and wheels do you have?

[kevinw]

the rear has 15X8 rallys. yes, I want the same size all the way around. the seller said the rims were GM rallys. I don't know the back spacing on the rears. but I hear either 4.25 or 4.5. I am looking at VISION AMERICAN MUSCLE 55 Rally Series silver wheels from Summit racing. these are 15/8 with 4.25 backspacking.
