	abstract = {<p>In this paper, we consider the monoid DPW_n of all partial isometries of a wheel graph W_n with n+1 vertices. Our main objective is to determine the rank of DPW_n. In the process, we also compute the ranks of three notable subsemigroups of DPW_n. We also describe Green{\textquoteright}s relations of DPW_n and of its three considered subsemigroups.</p>
