Y tires on eSpacetourer?

Hello everybody, in my vehicle license this is on our Spacetourer (electro) tyres of the size: 225/55 R17 101Y belong Y = speeds up to 300km/h The eSpacetourer regulates at 130km/h. Is there a higher sense for this or can I also have flaps in V (up to 240km/h) drawn up? What would be very easy to get with winter tyres…
