merc rims are bolt onto a bay, sometimes the stud holes need taking out at merc ones are 12mm bay 14mm centrebore is ok
I'd go with "horrible" but it's well known I don't like 99.9% of wheels that aren't the originals. Sick Boy has the only ones I've ever thought looked good on a bay. They'd look good on yours too I think, but don't know what they are which is why I tagged him.
Sorry for the late reply Zed I have been having logging on difficulties. I've got to admit the wheels are probably why I bought the van in the first place. I know they are 14" but not anything else - sorry.
