the specs of the Original BMW 20" rims is :

front: 8.5 J x 20 ET 25 (245/40 R20 99Y)
rear: 10 J x 20 ET 41 (275/35 R 20 102Y)

and somewhere in the specs there is a minimum weight rating per wheel but unfortunately I don't know where to find this.

edit: at least I found something:
the weight rating per wheel is expressed in the Load Index of the tyres
so for the fronts: 99 means 750 kg, for the rears 102 means 850 kg and Y is the max Speed index of the tyre (Y = up to 300 Km/h)
