The 5.5 inch wheel has a 42mm offset.
Porsche 6x15 5 bolt Fuchs have a 36mm offset
Porsche 7x15 5 bolt Fuchs have a 23.3 mm offset.
The ultrarare 7x15 911r wheel has a 49mm offset.
There are threads galore about "will this wheel / tire combo fit" , so please read through them.
For 4 bolt wheels, your options may be more limited than the 5 bolt wheels and be mindful that "VW" wheels are often either narrower, or have a different offset.
When going larger than 6 inch wide, ride height, camber, spring rate, rolled fender lips and tire size all come into play.
Imho, the best find widest used wheel that fits easiest is the 6.5x15 minilite with a 205/50 tire.
If you swap to Porsche 5 bolt wheels, the 6x15 is the easiest to fit. The rear of these cars is where fitment gets harder than the front, unless you add flares.
Thank you for the information - they are very helpful. I do not want to change the rims to other original ones that were factory-fitted, and I will not change four bolts to five bolts. I want to make custom rims on a CNC machine - this will be my pattern and that's why I need parameters. I noticed that in the USA people choose wheels according to the width of the rim and the width of the tire, and in Europe, people choose the wheels according to the width of the rim and the offset, and finally they choose the tire so that it fits and does not rub against the body. That's why I had a problem with finding a topic that interests me on the forum. Do you know exactly what parameters of 16-inch rims must be (width, offset) so that there is no problem? I want a narrower tire, i.e. 185x55x16 or 195x50x16. I was planning to build myself 6.5 inch wide 16 "rims, but I don't know what offset. Thank you for your help
