Hey,
What are the biggest 15" rims you can fit on a 78-87 elcamino or monte carlo ? What width and backspacing ? Can you fit 7 inchers all around or some 8's in back with 6.5's in front ? any ideas ?

Almost positive you can fit 8inch and whatever stock backspacing is. 7's will fit for sure SS montes come with 7's.

I've seen 15" x 8" zero offset wheels on some of the GM "sisters" to the Monte Carlo. P245/60R15 was the largest tire I saw fitted to one of those without extensive body modifications.
