A guide wheel for use with the suspension assembly of a snowmobile vehicle is provided with an embossed rim surface. The later is formed of a succession of convex and concave surfaces, the convex surfaces contacting the inner side of the lower run of the snowmobile track while the concave surfaces are so disposed as to avoid contacting pressure on that part of the snowmobile track in which lies transverse reinforcing rods embedded in the track.
