So here is what I have: I have a 2011 Grand Caravan with 16" Wheels. I am looking at these:

I think these are the newer stock jeep wheels.

I am pretty sure the bolt pattern is the same, I am just concerned about the back spacing.... anyone have any specs to compare about both

 

The only way to find out is to try one. If you know of a jeep owner or you have a jeep. Take it off and try it. Because I don't know.
