BMW 3 Series (E46)

Covered as: BMW 3 Series (also: E46, 325i, 330i, 330Ci, 330i ZHP, M3).

BMW 3 Series (E46, 1999-2006)

25 fitment answers · 8 known problems · 8 build entries. Body: sedan, coupe, convertible, wagon.

Bolt pattern	5x120
Hub (center) bore	72.6 mm
Lug thread	M12x1.5 bolts (60-degree cone seat)
Factory wheel sizes	16x7.0 not stated by BMW (guides: ET47), 205/55R16 (2004 only (confirmed in the 2004 sedan brochure), 325i / 325xi sedan (Style 45)) 17x7.0 not stated by BMW, 205/50R17 (2004 only (confirmed in the 2004 sedan brochure), 330i / 330xi sedan (Style 137)) 17x8.0 not stated by BMW, 225/45R17 (2004 only (confirmed in the 2004 sedan brochure), Sport Package sedans (Style 119)) 17x7.5 front / 17x8.5 rear not stated by BMW, 225/45R17 / 245/40R17 (2004 only (confirmed in the 2004 sedan brochure), Optional Style 68M staggered wheels) 18x8.0 front / 18x8.5 rear ET47 / ET50 (wheel libraries), 225/40R18 / 255/35R18 (2003-2006, 330i / 330Ci Performance Package (ZHP), Style 135M) 18x8.0 front / 18x9.0 rear ET47 / ET26 (wheel library), 225/45ZR18 / 255/40ZR18 (2001-2006, M3 coupe and convertible, Style 67M)
Note	Offsets come from wheel libraries, not BMW. One wheel guide lists the ZHP as 17x8/9 ET47/ET26, which matches the M3's Style 67 offsets rather than BMW's 18-inch ZHP spec; we follow BMW. 330i brakes are larger than the 325i's, so small wheels that clear a 325i may not clear a 330i (not tested in any source read).
