Mercedes Viano wheel fitment
Mercedes Viano wheel fitment comes down to two things: the factory hub spec, and how far the aftermarket width and offset can move from it. Both are here for the Mercedes Viano (I) W638 (2003–2010).
| Bolt pattern (PCD) | 5x112 |
| Centre bore | 66.6 mm |
| Bolt / thread | M14x1.5 (bolts) |
| Wheel-bolt torque | 120 Nm |
| Seat type | radius |

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6J–9J | ET5–ET67 |
Width and offset move together: roughly 8 to 10 ET more for every extra 1J keeps the wheel inside the arch. Final offset and any spacer come from the fit-check.
