BMW 8 Series wheel fitment — E31
BMW 8 Series wheel fitment
Everything below is what the fit-check uses for BMW 8 Series wheel fitment: the factory bolt spec first, then the width and offset window that clears the arches and the brakes on the BMW 8 Series E31.
| Bolt pattern (PCD) | 5x120 |
| Centre bore | 72.5 mm |
| Bolt / thread | M12 x 1.5 (bolts) |
| Wheel-bolt torque | 115 Nm |
| Seat type | tapered |
| Factory setup | staggered |
| TPMS | none |
Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8J–8.5J | ET0–ET15 |
| Rear (staggered) | 9J–9.5J | ET5–ET21 |
Go wider and the offset has to rise with it, about 8 to 10 ET per extra 1J, or the wheel pokes past the arch. The fit-check settles the exact offset and any spacer.
