There is one exception. You can get those fold up bicycle tires, without the wire bead, that also fit the Tomos rim. It's an easy way to carry a spare tire, for emergency use only, at slow speeds, until you can get a real moped tire. You just have to remember what you are riding on. Like those donut spares cars use. You have to go slow, and replace it with a real tire asap. It's not that dangerous as long as you know about it. In an emergency, you have to do what you have to do. But I would never recommend a bicycle tire for regular use on a moped, they are just not strong enough. Peace. Jerry.
