A couple months ago I was browsing a Ford Transit Connect forum and several people had reported that they were able to use Volvo alloy wheels on the previous generation Transit Connect without modifications. It would not surprise me if Ford was trying to use common wheel bolt patterns across vehicle brands back then on purpose.
I believe that the steel wheels on the old Transit Connects were 15-inch in diameter. So this particular steel wheel would not be suitable. But will other Ford wheels fit your Volvo, including the larger allow wheels used for Transit Connects?
