The invention discloses a steel wheel type road roller and a rolling wheel thereof. The rolling wheel comprises an outer steel wheel, an inner steel wheel and at least two spokes, wherein the outer steel wheel and the inner steel wheel are coaxially arranged; the spokes are connected between the outer steel wheel and the inner steel wheel. According to the rolling wheel, a storing space formed by the outer steel wheel, the inner steel wheel and the spokes is fully utilized and filled with filling materials such as liquid or granular solids; the overall operation is convenient and quick; the model and tonnage of the road roller can be simply and conveniently adjusted; compared with a traditional manner of adding a balancing weight to a loading device, the aforementioned manner of filling the filling materials has the advantages that the added filling materials can directly act on a compressing object, the weight increasing effect is obvious, and the usage amount can be accurately controlled after the density, storing space and volume of the filling materials are known; the filling materials with flowability are low in cost by being compared with the steel and other expensive materials, so that the economic advantage is great.
