On Road Wheel/Tyre Combo for CAT SX

[CW_]

Does anyone know for definate if these are the same fitting as the rev lite rims that come as standard on the CAT SX with the cross bar rather than hex type fitting?

Or does anyone have any other suggestions? just want something cheap and cheerful for a bit of on road fun over the winter

Thanks
