I have forgotten

5.5" is what I remember...

14x5.5 or 15x6 or 16x6 or 16x 7 or 16x8 or 16x9 rsr style 15x7 will fit under the stock rear 914 fender well

i have rubbing issues with mine and there 15x6s with Komho v710`s ....16x9and 8and 7 i respectfully disagree

There are many variation of these wheels, with many offsets.
Also the cars vary alot.

The stock four bolt fuchs are 5.75 inches wide...not quite 6.

Many of the above wheels do in fact...note the word fact....fit under narrow bodies cars.
Use of the correct offset, along with wheel spacers are what make them fit properly.

If you are asking about 4-lug, then they are 5.5.
Five lug, there are a bunch of variations as noted.

I am getting old. I saw fuchs and six inch and immediately thought of the five lug. I quoted the sizes of the five lug fuchs that fit the 914-6 or 914 or 914-6 gt. The four lug fuchs is 15x5.5 but we will soon have from Australia 16 inch fuchs in seven and eight inch, sevens fitting stock fenders or flares (two different offsets!)

maybe the wheels i have are not the proper offset ..how do you tell ?if there not proper i have a set of cookie cutters for traid 15x6 my fuchs work very goodwith yokohama ao32s no rub ...tire size on both 205-50-15
