So this should now be official range of the EPA list. As stated before the 20 inch with wider tires slaughters the range but for some that will be more then enough.
This is from inside EVs they have more in depth and details so credit to them for summarising it so well

This is from the official document for those wondering when the time comes to change tires when undoubtedly the ones that comes with the cars wears out.
The BMW i4 eDrive40 is fitted with standard 18-inch light-alloy wheels while 19-inch
wheels are optional. The BMW i4 M50 includes 19-inch M light-alloy wheels with
mixed-size tires. Additional 19-inch and 20-inch wheels are optional.
A more advanced version of BMW’s standard Tire Pressure Monitor is found on the i4.
The system’s sensors relay data on tire pressure and temperature for each individual
wheel, which is then processed to generate corresponding readouts in the Control
Display. The Tire Pressure Monitor also factors in specific data on the tires fitted,
including manufacturer, dimensions and production date, which can now for the first
Corporate Communications
time be scanned from a QR code at the factory or service partner. Exclusive to BMW,
this system simplifies use of the tire pressure indicator in the iDrive menu. In the menu
item for tire selection, the driver has only to indicate whether the vehicle is partially or
fully laden to view information on both the ideal and current tire pressures and decide
whether there is any need to adjust them.
A digital tire diagnosis function helps advise the owner of tire wear by processing the
data from the Tire Pressure Monitor in the BMW backend together with the pressure,
temperature and wheel speed readings to forecast the remaining tire life. Customers
can be notified via the My BMW App, for example, if action needs to be taken
