Fits Most Tire Size: Our wheel clamp lock fits a wide range of tire sizes, ranging from 6.3 to 15 inches (160-380mm), securely locking the tire in place. It is suitable for most tire sizes, requiring the tire's section width within the 6.3-inch range and the radius within the 13.8-inch range. 12-inch Suction Cup: A larger suction cup design effectively covers and protects the wheel's lug nuts, preventing thieves from removing the entire tire. The rubber ring around the suction cup protects the wheel's surface from scratches and ensures a secure fit, making it difficult to pry open. High Theft Deterrent: This trailer wheel lock boasts a unique all-copper lock core, ensuring that it comes with two exclusive keys to prevent any chance of mutual key opening. The adjustable arm is concealed within the lock, making it difficult for thieves to forcibly pry it open with tools. Additionally, the lock's interior features spikes that puncture the tire if tampered with, further enhancing security. Reliable Steel Construction: Built with a heavy-duty and reinforced all-steel structure, this trailer tire lock is both robust and dependable. High-quality welding techniques minimize large gaps, reducing the risk of thieves sawing it open with tools. The eye-catching paint coating provides effective rust resistance and durability and is a strong visual deterrent. Tire-Friendly Design: The claw of the wheel lock is designed with rounded edges, avoiding harsh right-angle edges. It conforms better to the tire, and the addition of rubber padding on the surface prevents scratches to both the tire and the wheel hub. Our wheel clamp lock is exclusively intended for vehicle protection, ensuring it won't harm your tires or wheels during use.
