Did you glue the screws into the wheels? If so that is a bad idea because its going to be a pain to take them out to replace the tread (yeah the tread wears and you should change it before each regional you go to). Unless you have extra wheels you have done this to, you may wanna figure out how to take the glued in screws out.

Or if you glued the treads on it will also be a pain to take them off to change them. either way just screws or better yet if you can use them are pop rivets. Good luck.

Sorry if i read it wrong.
