A vehicle wheel comprises a wheel rim having first and second sidewalls defining a rim trough, a tire having a tire bead positioned in the rim trough in engagement with the first sidewall, and a bead lock positioned in the rim trough adjacent the tire bead. The bead lock is movable between a locked position and an unlocked position. The bead lock includes an actuator positioned in the opening and including an exposed portion accessible from outside the wheel. The bead lock can further include a band positioned in the rim trough and including two free ends movable relative to each other. The bead lock can further include a tightening mechanism secured to the two free ends. For example, the tightening mechanism can include a winch and a cable wrapped around the winch and secured to one of the free ends.
