Hi, I am looking to get an additional set of wheels for my GGH25 Vellfire. It came with 235/50/18 set. Someone local listed a set of wheels for Alphard, but those are 215/65/16. I did some research and wheel-size dot com states GGH25 came with either of those from the factory. Can this info be trusted? Are there any other considerations while changing the wheel? Is it just a simple swap, provided that they fit? Many thanks thanks, Matt.
