Note that the plastic hubs are prone to shrinking over time and these tyres are made to fit hubs with some shrinkage. So they may be tight or loose depending on your hubs. Use a drop of super glue if loose and a piece of emery paper on the ID of the tyre if they are tight. Warm water also helps to heat the tyre and hub during fitting.
