When the mettalic ring is heated it will expand becuse metals expand on heating.
After that, when you will try to insert it on the wheel, it might not fit exactly.
Thus pouring some cold water, the ring will slightly decrease in size because metals contract on cooling and will fit the wheel perfectly and will not come out.
