Talitha rims at the XC60

Moin together Last year I had a complete set of wheels Talitha (Diamond cut/Black Stone) 9×20 with 255/45 R20 Pirelli’s for my XC60 with my dealer. Unfortunately I had to find out after about 2 months an imbalance on the steering wheel (light fluttering). Since I did not drive over curbs or in other terrain except possibly a milled road in urban traffic with a maximum of 40km/h, and I am the only driver it is inexplicable to me why these rims now have a Be 3 out of 4 rims have this side impact. Can’t describe this now in moderation and numbers because I couldn’t hold a clock to the balancer, but the one is quite clear and the other two a little less but just enough to make the steering wheel flutter. I asked my master contract workshop and my former master contract workshop how something like that can happen, both of them thought that this didn’t just happen, the one said just that the I was still with the Tüv and he meant whether it was the material or whether there was anything that was difficult to say. An expert opinion on this would be difficult to draw up. I am now mainly interested in the maximum wheel load of such a rim since I find it nowhere before I bother the dealer again. I now make the wheel load depending on whether I get these rims again or not. With other rim manufacturers it varies from 680kg -1024kg per rim what I’ve seen. I’m just surprised that happens with such a rim. I decided especially for an original because I thought buying what good what thinks, which was only manufactured and developed for the XC60. well… so if someone can tell me the wheel load of this rim I would be very grateful MFG
