Thanks guys. Seems like there is no stock option for me. I have a pair of 16" wheels, but I rather have 15" because of a particular tire I want to use.

I'm pretty sure I have seen 15" regular wheels with 8-lug centers. But they could have been custom made of course. It wouldn't be difficult to take the centers out and turn them down to fit a 15" rim.

I will continue the search and if I can't find anything I will go with 16"

Thanks,
Magnus
