My conclusion, the EPS had to recalibrate based on the new tire size/width.

Edit: Chatgbt quick answer: "Steering recalibration typically involves resetting the steering angle sensor, which is part of the vehicle's electronic stability control system. This recalibration is usually done by turning the steering wheel to its full lock position in both directions after the tires have been changed." Is this the way it has to be done?
Never heard of a tyre / width change causing such issues..but I’ve only done it 5 times in 7 years…
