If you enjoy drag racing, beadlocks are also beneficial. One issue that might arise at the high speeds that drag racers travel is that tires can get loose and spin wildly independent of the inner tube. This is extremely dangerous since it makes brakes practically impossible. Beadlocks prevent this from happening by locking the tire to the wheel rim. The car cannot move forward or backward because the bead of thread that locks the tire to the wheel keeps it tight against the road. Another danger associated with beadlocks is heat buildup. Since the tire no longer has a belt to spread the load out over a larger area, it must be made stronger in order to carry the same amount of weight as a conventional tire. This means that it will be built with thicker walls, which results in more heat being generated when braking or turning. If you live in an area where tires are not required and don't care for heat, beadlocks may not be for you. Beadlocks were originally designed for use on motorcycles, but they have now been adopted by cars too. They are usually installed by drilling holes in the wheel center and then threading the lock's beads through them. When you turn the key, the trunk lids and hoods of these vehicles come down automatically because their locks work on the same principle as motorcycle beadlocks.
