AFAIK, 215/75/15 is the largest tire that is practical to use on the VW
SA 15" wheels without other modifications. I refer to Syncros here but I
think it also applies to 2wd models.
This is also the largest tire that can be made to fit in the spare tire
area up front though mods are needed to make it go in there. Different
brands have slightly differing dimensions. My numerous fitments of this
size on Syncros and 2wds were all Michelin.
