Volvo S60 steering wheel jerks from 100 kmh after changing wheels

Hello together, I ordered for my Volvo s60 Bj 2003 new rims 235 45 R17 with Pirelli tires at ATU and had them installed. Are you on it the steering wheel from approx. 100 KMH but not always sometimes when accelerating and braking is not to be felt. Did ea complain they have rebalanced and looked at everything. Was the first few hours everything okay until it jerked again. Am really despairing can help me there? Had 205 55 R16 with contis before thank you in advance Gruss niko
