# Can you use expansion and contraction in a cycle tire?

yes, we can use expansion and contraction is possible  in a cycle tire.  the tire is fit  on the wheel using expansion and contraction only.  first, the tire  is heated  to expand so that it can fit on tire easily. then it  is allowed to cool down so it can not come out of wheel.
