BMW 3 Series G20 wheel fitment
The G20 uses 5x112 hubs, so earlier 3 Series wheels do not bolt straight on. Popular road setups retain a rear tyre stagger, with tyre pairing particularly important on xDrive cars.
5x112 bolt pattern · 66.6 mm centre bore · Stock wheels: 17 × 7.5, 18 × 7.5, 18 × 8.5, 19 × 8, 19 × 8.5 inch · Stock tyres: 225/50 R17, 225/45 R18, 255/40 R18, 225/40 R19, 255/35 R19

Explained in our guides
Read these before choosing wheels for the 3 Series: they explain the offset, fitment and hub numbers in this guide.
- Wheel offset explained: choosing ET without guessingUnderstand positive and negative wheel offset, calculate inner clearance and outer position, and choose an ET using measurements from your own car.
- Flush, poke and tucked fitment: measure the whole tyreUnderstand flush, poked and tucked wheels, calculate how width and offset change the look, and check clearance beyond a parked side-on photograph.
- Staggered vs square wheels: tyres, rotation and AWDCompare square and staggered wheel setups, calculate front-to-rear tyre diameter, and understand rotation limits and all-wheel-drive requirements.

19-inch road stagger
- Front
- 19 × 9 inch, ET25 · 235/40 R19
- Rear
- 19 × 10 inch, ET38 · 265/35 R19
A documented direct fit using a tyre pair listed as xDrive-compatible. Aftermarket suspension must be checked for reduced inner clearance.
Width and offset guidance
Offset range
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Common width limit
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Clearance notes
- The G20 hub is approximately 66.56 mm, normally sold as 66.6 mm. It differs from the 72.6 mm, 5x120 F30 arrangement.
- These examples cover the G20, not the G80 M3.
- Do not substitute arbitrary front and rear tyre sizes on xDrive. Apex identifies some apparently similar staggered pairs as unsuitable.
- Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
