In SharePoint online i created a document library. In the new experience view you have the possibility to show the list with a tiles view.
is it possible to do it as a default view? If i make a view the tiles setting is not saved
When creating a view (or editing one) you set the Style property to Document Details. As with every View, you can set this one as the default view.

I don't think we have that feature yet to save tile view as default.
You can check the changes made to tile view and try to create similar custom view. That might help.
