BMW X4 F26 — Wheel Fitment & Specs
Overview
The BMW X4 F26 is a compact luxury crossover SUV manufactured by BMW from 2014 to 2018. It is marketed as a sports activity coupé (SAC), featuring styling elements and roofline of a traditional two-door coupé, making it a sportier version of the X3 with reduced practicality due to its sloping rear roof design.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8J–9J | ET22–ET42 |
| Rear (staggered) | 9.5J–10J | ET30–ET46 |
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 20,518 BMW X4 on UK roads, placing it in the top 10% 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.
