BMW 3 Series wheel fitment — VII G20/G21/G28
Overview
The BMW G20/G21 is the seventh generation of the BMW 3 Series, introduced in October 2018 and featuring a facelift in July 2022. It includes sedan (G20) and wagon (Touring, G21) variants built on the CLAR platform with increased use of high-strength steel and aluminum. The car is produced globally across multiple plants including Munich, Shenyang, San Luis Potosí, Chennai, Rayong, Jakarta, Kulim, Araquari, Chu Lai, and Mexico City. It replaces the 3 Series Gran Turismo body style with the BMW 4 Series Gran Coupé.
History & notable variants
Development began in late 2015 when Alexey Kezha's design was chosen by BMW management. The G20 was unveiled at the Paris Motor Show in October 2018 and went on sale in March 2019. Notable variants include the M340i, launched in spring 2019, and the plug-in hybrid 330e model introduced at Geneva in 2019. The facelifted version (LCI) was announced in May 2022 with significant interior updates including a dual curved display.
BMW 3 Series wheel fitment
Everything below is what the fit-check uses for BMW 3 Series wheel fitment: the factory bolt spec first, then the width and offset window that clears the arches and the brakes on the BMW 3 Series VII (G20/G21/G28).
| 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 | 6.5J–8.5J | ET12–ET45 |
| Rear (staggered) | 8J–9.5J | ET29–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.
