The invention discloses a road wheel for sowing machines. The road wheel comprises a wheel hub, a wheel rim and a tire, wherein the wheel hub, the wheel rim and a steel ring are coaxially arranged; a plurality of mounting holes which are uniformly arrayed are formed in the wheel rim; a plurality of supporting plates are uniformly mounted between the wheel hub and the wheel rim; a group of symmetrical connecting holes are formed in each supporting plate; a pair of connecting holes in each supporting plate is mounted on the corresponding mounting hole of the wheel rim; tire patterns are formed on the surface of the tire. According to the road wheel disclosed by the invention, the width of the tire is half of the height of the tire, so that the contact area between the tire and the ground is increased, and the pressure of machinery to the ground is reduced; besides, dust pollution is reduced because of anti-pollution ingredients in the tire, so that the workload of cleaning the tire is effectively reduced; through the adoption of the supporting plates in streamlined structures, the oblong mounting holes, and the shapes of the tire patterns, the stress concentration of the wheel is reduced to a certain extent, so that the service life of the wheel is prolonged, and the cost is reduced.
