The present invention provides a wheel and a rim (11) with a weight reduction inner flange. The rim comprises an inner flange, a middle portion and an outer flange which are all annular and connected end to end to form an annular rim, wherein the inner flange or the outer flange comprises multiple groups of edge weight reduction sockets (21) arranged side by side on one side of the inner cavity of a hub, and multiple groups of inner weight reduction sockets arranged side by side are provided inside the edge weight reduction sockets on the rim; a group of edge weight reduction sockets comprises a first edge weight reduction socket and a second edge weight reduction socket at the edge of the inner flange or the outer flange, and the first edge weight reduction socket is in the shape of a right-angled triangle having round angles. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the inner flange of the hub and selecting the size of the weight reduction sockets.
