BMW 3 Series wheel fitment — VII LCI G20/G21
Overview
The BMW G20 and G21 are the seventh generation of the BMW 3 Series, introduced in October 2018. They consist of a sedan (G20) and a station wagon (Touring/G21). Production takes place in Germany, China, Mexico, India, Thailand, Indonesia, Malaysia, Brazil, and Vietnam. The G20 is based on the BMW CLAR platform with increased use of high-strength steel and aluminum, featuring MacPherson strut front suspension and multi-link rear suspension. Compared to its predecessor (F30), it is lighter by 55 kg, longer by 85 mm, and wider by 16 mm.
BMW 3 Series wheel fitment
Start with the hub. The BMW 3 Series VII LCI (G20/G21) spec table gives the bolt pattern and bore; the second table is the aftermarket window for BMW 3 Series wheel fitment.
| 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 |
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.
UK popularity & demand
Based on DfT VEH0124 vehicle-parc data (2025), there are approximately 467,458 BMW 3 Series on UK roads, placing it in the top 1% of car models by volume across our fitment database.
That makes BMW 3 Series wheel fitment a high-demand spec to keep in stock. It is one reason we track it here.
