Tyre size in the new car slip

Hello, I have a question about the tyre sizes in the new car bill. I bought my Vento almost 2 years ago. I also got the new car bill there. I believe registration certificate part 2. On my car there are 195 tyres, which were also registered in addition to the 185s, because the two are the standard tyres for this vehicle. In the new bill there are now only the 185s in it. Since I had to think about a traffic control, i I made a copy of the old ticket and have it certified so that I am practically on the safe side with a check and the race management can not strangle in me. This copy was also used for a check, the race management was also somehow not in the picture, because of the new show, because only the 185s were registered. Now I ask myself, what does this look like now? Why are the 195s not registered with me anymore? because some regulation, which size one may have smaller or larger on it? my first winter tyres were 175s, which were still registered in the old, but in the new of course not… Hope you can help me further so that I know about it.
