Question about winter complete wheels

Hello together, I have been the owner of a SC Cupra 290 for 2 weeks. Since the winter is already at the start I of course also need reasonable winter tires. Before I order my desired rims online, I have 1-2 questions to you, which you can answer for sure. 1. According to papers I can drive rims or tyres with a press-in depth of 49 or 51. 225/45 R17. Is it ‘no matter’ if the press-in depth differs with my desired rims, e.g. ET 45? 2. How does this look with tyre pressure Do I have to buy special tires so that my Cupra doesn’t complain that he no longer detects tyre pressure? (Heard about any sensors on the valve) Thank you very much 😉
