A wheel for a skateboard, roller skate or the like has a radial surface arranged to provide contact with the ground, said radial surface comprising areas of at least a first material and areas of a second material, said second material having at least one mechanical property differing from that of the first material. The first and second materials are arranged in such a way that they form a pattern on the radial surface which varies around the circumference of the wheel. This enables the adaptation of the behavior of the wheel in a very flexible way. |
