Load rating certainly is something to look for.
For my current phev it was also the case. The "flow form" wheels seemed to be light enough and have proper load ratings.

Will you looks for aftermarket but BMW wheel or from other company?

I'm not planning to get replicas of bmw styles, if that is what you mean.
Rather some good quality wheels from BBS, OZ or other "well known" brands

OK I will have BMW19" on my I4 so Will check on my side for 18" winter wheels, do you think that 17" will be feasible on !4 40?

I suppose 17" will look too small, but if the stock winter wheels are 17”, I'm probably going to live with them.
For summer, I will look for 18-19" wheels.
There was nothing wrong with the BMW wheels, but I don't like the idea of paying 2000€ for wheels that I have to give away for free after 36 months.

It appears the configurators of wheel companies have the new 4 series coupe implemented, but not GC.

At least MAK and Ronal/speedline had some wheels that could be visualized on the new 4 coupe.

Ronal? I want 20" Teddy Bears.

I believe Ronal makes oem wheels for Mercedes.
At least my 2014 E -class had Ronal stamped on the original wheels.

Edit: and the teddy bears would be cool 😅

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.

The lightweight OZ wheels were often with 590 or 650 kg load rating.
My original plan was to get some light OZ wheels, but it seems I need to look further.

But hwat is is official max load / wheel anyway? Imcant find it?

Now I found this dealer wich gives max load specifications:

Some dealers have links to TUV certificates on their webstores. They include a max load number, which I assume is reliable.
Also some manufacturers include the info on their website. But most don't, which makes it hard to find alternatives.

 

[mpr]

Is that wheel the Imaz FF481 ?

 

[mpr]

Somehow they looked familiar
I had the black-polish version in my previous car.
Did you check the load rating on the 19" size? The 18" I had would have been too low, and it seems impossible to find the numbers online.

 

[mpr]

That's good news
More options for wheels. They seem to have reasonably priced flowform wheels.

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.

 

[mpr]

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.
