2021–present · gran coupe
The i4 is the electric version of the 4 Series Gran Coupe. Depending on market and trim it came on square 17 or 18-inch wheels or staggered 18 and 19-inch sets, and the M50 always runs staggered 19s. It is heavier than a petrol 4 Series, so owners changing wheels look for designs with a high enough load rating as well as the right offset, and 20-inch sets are the usual upgrade.

Read these before choosing wheels for the i4: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Apex lists this as its popular aggressive fitment for the i4, a direct bolt-on with 245/35 R20 or 255/30 R20 all round, suitable for xDrive. It warns that 3 to 5 mm front spacers may be needed with some aftermarket suspension or wide-running tyres. Three Piece's gallery also shows a 2022 i4 on Vossen HF3 wheels in 20x9 ET25.
Apex's staggered option for the i4, with 245/35 R20 front and 275/30 R20 rear. A 255/30 R20 front is also listed, but Apex says that combination is for rear-wheel-drive cars only.
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.
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.
Upload a photo and start with a look that suits the i4. Try the wheels, colour and stance before you spend on parts.

These tools start with the eDrive35 / eDrive40, 18-inch staggered front size. Choose your own trim or axle in the calculator if it differs.

The bolt pattern and hub are the same, but the i4 is heavier. Check that the wheel's load rating suits the i4 before fitting it.
