The center bore for a wheel in the E9X M3 is 72.5 and the bolts are 12x1.5 . I am exploring the possibility or putting on winter wheels with the same center bore, but built for a different BMW car with lug bolts that are 14x1.5 ( Oh yes, offset and bolt pattern are compatible). In theory, the wheels would fit but the E90 bolts being 2mm thinner, might not seat the wheel properly against the hub since the holes may be larger. Is this assumption correct? Is the taper in the bolts different? Somebody out there must have acquired some experience with this. The only other way I can find out is to travel 260 miles and check the fit in someone else's garage.
