I don't recall ever seeing 8" wide wheels but 7" is common. These wheels are very high offset like 55 or 59mm. You may need 20 or 30 mm spacers and really long lugs and then they may stick out too far. The ideal offset is usually ~30mm.

Without seeing them, someone is offering a set of 2001 Eurovan, steel wheels, stamped J8x16. Does anyone know if these are 5x112, offset, and if the centers have to be opened up? Thanks,
