I have just aquired some 13x7 inch steel wheels.
The pcd is 100 which is the right fitment but centre bore on the wheel is slighty to big and there is no support from it. So the wheels are hanging off the bolts only.

Is this common on other non vw wheels or should the centre bore be a tight fit on all wheels fitted.

Don't want to fit the wheels if there are not going to be safe or cause damage!

Heard something about adaptor rings but don't know what they do!

Any advice would be really good!

Cheers
