Traction control system for vehicle

A vehicle comprising:

• a vehicle body;
• a wheel arranged to rotate around a wheel rotation axis in relation to the vehicle body while being in contact with a contact surface;
• and
• a traction control system for controlling a contact force between a wheel rotating around a wheel rotation axis and a contact surface, the traction control system comprising:
• at least a first weight controllable to move around the wheel rotation axis when the traction control system is coupled to the wheel;
• and
• a weight guiding arrangement configured to guide the first weight in such a way that, when the first weight moves around the wheel rotation axis, a center of mass of the first weight follows a first path defined by the weight guiding arrangement, wherein the first path exhibits a first portion with a first radius of curvature, and a second portion with a second radius of curvature, larger than the first radius of curvature;
• wherein the traction control system is controllable to be coupled to the wheel in such a way that the at least first weight of the traction control system moves around the wheel rotation axis.
