Just to add in regarding spares that come with different bolts... my old Alfa (145 GTA) had a space saver spare and a second set of bolts, because the offset on the alloys was such that if you tried to use those with the space saver, they would protrude through the hub and contact the disc.... (it also had a foible that if you had a front puncture you had to take the back tyre off, put the space saver on that, then jack the front up to put the back wheel on the front, all due to the larger F40 brembo calipers on the front discs... not fun in the rain on the M25)
