BMW Z4 wheel fitment — III G29
BMW Z4 wheel fitment
BMW Z4 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 BMW Z4 III (G29) (2018–2026).
| Bolt pattern (PCD) | 5x112 |
| Centre bore | 66.6 mm |
| Bolt / thread | M14 x 1.25 (bolts) |
| Wheel-bolt torque | 140 Nm |
| Seat type | tapered |
| Factory setup | staggered |
| TPMS | direct |
| Run-flat | Yes |
Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8.5J–9J | ET25–ET36 |
| Rear (staggered) | 10J–10.5J | ET37–ET45 |
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.
Overview
The BMW Z4 (G29) is a roadster produced by German automobile manufacturer BMW. It was introduced in 2018 for the 2019 model year as a successor to the E89 Z4, marking the return of the soft-top roof to the Z Series sports cars. The G29 Z4 is based on the Toyota-BMW joint sports car architecture and features a front-engine, rear-wheel-drive layout with weight savings compared to its predecessor. It was assembled in Austria by Magna Steyr.
