A vehicle traction element (10) for providing traction relative to a surface over which a vehicle equipped with the element is to travel comprises a rotary or circulatory member, especially a wheel (10a), which has a periphery (12) and is provided at the periphery with a series of resiliently deflectable surface-engaging arms (11). The arms (11) are equidistantly spaced around the periphery (12) and have the same shape and orientation. In particular, each arm has a root (13) at, and a tip (14) remote from, the periphery (12) and each arm comprises an inner curved portion (15) starting at the root and departing from the periphery at an acute angle (a) on a concave side (15a) of that portion (15) and an outer curved portion (16) ending at the tip (14) and curved in opposite sense to the inner curved portion (15). The resiliently deflectable arms (11) allow relatively smooth motion over normal surfaces, but can function similarly to claw-tipped legs to lever the wheel over an obstacle.
