The configurator lists Japan Racing SL01 for the i4.
Last time I checked, the load rating is not enough for i4.
Also JR configurator doesn't show any wheels for i4, even if i4 can be selected.

I have contacted JR in Poland and they helped me configure a set of wheels for my i4 m50. 8.5x20" ET30 in front and 10x20" ET40 in the rear. They can handle a lot of weight, Max load is 750 kg, which times four is far more than the total weight of the car. They only weigh 9.9 and 10.5 kg and the 868m 20" OEM wheels weigh 13.65 and 14.33 kg.

The max load should be more than the rear axle weight divided by two. I4 is not 50/50 distributed, and the rear is heavier.
At least in Finland total weight divided by four is not enough. On the rear, we need 775 kg.

Oh no. Then my Max load is not enough!!! I really hope those extra 25kg is no problem. How Do you calculate the axle rating? I cannot find any numbers for it.

The max allowed weight on rear 1550 kg.
The car itself does not weight that much. This is the weigh with the car loaded with as much people and luggage as allowed.
I don't know if that 25 kg difference really matters anywhere besides the yearly inspection.

I also think the numbers are precautions and safety by far. The actual breaking point is probably a bit over 800kg. I guess i wont floor it while heavily loaded.

I returned the wheels today, Ordering JR28 instead...

I guess you got them in 20"? Do you know if the 19" would fit as well with the max. load? I can't find any information on their homepage.

It says 690kg on the 19” on their website. So no. You need 775kg. 20” is 815kg.

Thanks! I cechekd their website but didn't found it. I hope we will see more such wheels with a higher load rating in the near future.
