These were run without spacers on an E91 320d. Whether the offset was right nor not I cannot comment but they fitted without issue on that car and I would have been happy to run them on mine if only they'd have fitted!
They are all 7.5jx17,
Fronts say IS25 offset, part number 2 229 480.
Rears say IS47 offset, part number 2 229 980.
Bear in mind offset can be different as clearance for snow chains is also allowed for, apparently.
