If you get the Model 3 Wheel Blade Style Cover Hubcaps, I would recommend that you use a piece of double-sided 3M adhesive tape to attach the colored Tesla center piece stickers to the wheel covers. I do not believe that the adhesive that comes on the stickers is strong enough to stay on the wheel cover. Other than that, those Blade Style Cover wheel covers are really nice.
If you just get the base model Tesla, the standard included wheel size for a Model 3 is an 18 inch wheel and the standard included wheel size for a Model Y is a 19 inch wheel. So no, the wheel covers for the Model 3 would not fit, BUT yes you can order these same type wheel covers for a Model Y in a 19 inch size.
