rim size question

Not unless they have a 5 on 4 bolt pattern (not likely as most of of the multiple bolt pattern wheels will have 4 1/2, 4 3/4 and maybe 5 on 5).
A particular aftermarket wheel back could have just about any back spacing, so that may or may not be an issue. Just measure actual backspace on what you have for wheels, then measure available clearance on the car to know for sure. You might need to be flexible on the desired tire size.
