1 new tires, axle measurement and set -> Do you need the steering wheel to stand diagonally?

Ahoi times a question about the chassis (V50). I recently got four new winter tyres on new steel rims. Unfortunately, after approx. 2000km the tyres had to be changed at the front right incl. rim. This was done, the axle was remeasured. So far – so good. Since then the steering wheel is slightly crooked (turned to the right) when driving straight. The elk drives and brakes straight ahead. I have of course addressed the friendly one to it. He thinks that the cause can and probably will have to do with the different running performance of the front tires. Nevertheless, he will look at the whole thing. I guess what will come out of it, and I’m not satisfied with it. Therefore, is this necessarily the question, as he said, that the steering wheel is somewhat oblique in the case of different running performance of the front wheels? Can this be related to the system with which the axle will be measured? If this should only be a lazy excuse, then give me powerful arguments. I’m not really solid in the subject, my area of electronics.
