BMW X3 wheel fitment — IV G45
Overview
The BMW X3 IV (G45/G48) is a compact luxury crossover SUV manufactured by BMW from 2024 onwards, replacing the third-generation G01 model. Built on the CLAR platform, it offers mild hybrid and plug-in hybrid powertrains. The fourth generation features a lowered roofline for a sportier silhouette and advanced interior technology like the full digital Curved Display with iDrive 9 infotainment system. Production occurs in multiple locations including South Carolina (U.S.), Rosslyn (South Africa), Dadong (China), Jakarta (Indonesia), Kulim (Malaysia), and Chu Lai (Vietnam).

| Bolt / thread | M14 x 1.25 (bolts) |
| Wheel-bolt torque | 140 Nm |

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8J–9.5J | ET5–ET30 |
| Rear (staggered) | 9J–11J | ET17–ET42 |
As a rule, each extra 1J of width wants roughly +8 to 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 123,411 BMW X3 on UK roads, placing it in the top 3% of car models by volume across our fitment database.
A parc that size is why BMW X3 wheel fitment is worth getting exactly right: a lot of owners are shopping for these numbers.
