A Beadlock is a device that securely fixes the tire to the wheel bead, commonly used in high-performance automotive racing. It is popular in motorsports and allows for reduced air pressure in tires to increase traction. Beadlocks are not legal for use on public roads. They are available in both aluminum and steel and are also used in All Terrain Vehicles (ATVs) for competitive racing. Tightening the lockring bolts is crucial to prevent tire damage.
A Beadlock is a feature found on a high performance automotive racing wheel. The bead lock is a device that securely fixes the tire to the wheel bead, by means of a bolt-on locking ring, to prevent the tire from coming off the rim. Available on both the inside and outside of the wheel, the most common bead lock wheel has a single lock on the outside bead. Popular in a wide range of motorsports, from drag racing to rock crawling, the most common form of competition using a bead wheel is dirt track auto racing. While dummy bead lock wheels are popular on street-driven four-wheel drive vehicles, actual bead locks are not legal for use on any public road anywhere.
Many competition vehicles operate with reduced air pressure in their tires to increase traction. This often leads to tires coming off the wheels when sliding sideways into a turn or dragging along the side of a steep rock face. In drag racing applications, the wheel often spins inside the tire due to the enormous amount of horsepower applied to the tires when hitting the throttle. Using a bead wheel, the tire is attached to the wheel by sandwiching the bead between the wheel and the bead or locking ring and securing the ring with bolts around the entire perimeter of the ring.
Most racing wheels that incorporate a bead are made from spun aluminum, but there are many steel wheels that work with a locking bead as well. Steel wheels are more durable in some environments where weight is not as significant a factor. Dirt track racing in some of the lower classes often allows the use of beaded steel wheels on the right side rear axle. Higher performance classes such as late model and speed cars often use aluminum wheels fitted with locks on both the inside and outside rear tires, with late model often running the locks on the front wheels. four wheels.
Small versions of the Beadlock wheel are manufactured for use on All Terrain Vehicles (ATVs) in competitive racing applications. To properly install a tire on the wheel, the lockring must be precisely adjusted to the manufacturer’s specific specifications. Failure to properly tighten the lockring bolts can break the sidewalls and beads of the tires. A loose lock ring can also cause severe vibration and punctures.
