BMW 1 Series II LCI (F20/F21) — Wheel Fitment & Specs
Overview
The second generation of the BMW 1 Series includes the F20 (5-door hatchback) and F21 (3-door hatchback), produced by BMW from September 2011 to May 2019. It is built on the BMW L7 platform, offering rear-wheel drive as standard with optional all-wheel drive xDrive. Unlike its competitors, it uses a front-engine layout for most models and was the first 1 Series to offer an optional all-wheel-drive system.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6J–8J | ET22–ET45 |
| Rear (staggered) | 7J–8.5J | ET33–ET45 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
UK popularity & demand
Based on DfT VEH0124 vehicle-parc data (2025), there are approximately 397,465 BMW 1 Series on UK roads, placing it in the top 1% of car models by volume across our fitment database. That makes its wheel fitment a high-demand size to keep in stock — one reason we track its exact spec here.
