A chassis (12, fig. 1) for a commercial vehicle (10, fig. 1) comprises a frame (14, fig. 1) upon which are arranged a front axle 20 including steerable front wheels 22, a first rear axle 30 including first rear wheels 32 and a second rear axle 34 including steerable second rear wheels 36. The second rear axle 34 is at a distance, e.g. more than two metres, from the first rear axle 30 in the longitudinal direction of the vehicle. The chassis also includes an actuator 38 configured to: receive at least one electric signal indicative of at least one steering angle of the front wheels 22; and actuate and thus steer the second rear wheels 36 on the basis of the received signal. The second rear wheels may be double wheels. The first rear axle may be arranged on the frame via a first suspension including metallic springs, and the second rear axle via a second suspension including air springs. The first rear axle may be driven and the first rear wheels may be non-steerable wheels.
