Rims do not come with spokes. To make a new wheel you need a rim, rim
strip (to protect tube from spoke ends), tube, tire, spokes, spoke
nipples, and don't forget the hub. By the time you add all that up, and
especially include the hassle of switching wheels out if you only have
one frame, you may realize it's much better to have a separate
unicycle.
I think you also asked something about fitting a wider tire onto the
same rim. This can be done as long as the tire is made to fit that rim.
The drawback of wider tires on skinnier rims is that they can fold over,
depending on what type of riding you do.
Try using punctuation in further posts. It will make it easier for us to
understand you, and it will also help you learn to use the language.
