Having a flat tyre today, tried pump it with air but failed, as I noticed it too late and the tyre is completely broken. 18″ tyre rear wheel flat, not so noticeable but does felt a little not right (like loosing some grip).
First time change tyre myself, so putting knowledge into practical.
Am glad that the spare tyre is having the same rim and the tyre is brand new. So I will get replacement later…later date.
