What is the appropriate thickness for towing wire rope?

A 16MM x 6-meter wire rope set is sufficient. Below is a detailed introduction about towing: Preferred Towing Bar: If the rear vehicle has brake issues or towing is required on icy or snowy roads, a towing bar should be prioritized. A rigid towing bar can prevent the towed vehicle from losing control of its speed if the towing vehicle pulls too hard or needs to brake suddenly. In fact, using a towing bar is generally safer even under normal conditions. Choosing the Right Hook: The towing hook should not just be able to 'hook' onto the vehicle; it must be securely fastened and properly installed. Always double-check that the hook is properly engaged before towing. If the hook comes undone halfway, it can cause significant trouble. Plan the Route: Maintain communication between the towing and towed vehicles. Choose a route with less traffic, better road conditions, and a shorter distance. Avoid areas with heavy pedestrian or commercial activity, underground parking lots, or other potentially hazardous sections to reduce the risk of secondary accidents. A walkie-talkie is ideal for constant communication, allowing immediate handling of emergencies. At the very least, use horn signals to communicate. Control Speed and Distance: Special attention must be paid to speed control and the distance between the two vehicles during towing, as even slight mismanagement can lead to accidents. Do not drive as fast as usual; maintain a speed of around 20 km/h and never exceed 30 km/h. Many vehicles lack vacuum-assisted braking when not running, so speed must be kept low. Additionally, maintain an optimal distance of 5-11 meters between the vehicles, ensuring the towed vehicle has enough time to react if the towing vehicle brakes suddenly.
Having run an auto repair shop for over a decade, I often get asked about tow rope thickness. Steel cables that are too thin can snap easily, while overly thick ones are cumbersome and expensive. For regular sedans, an 8mm diameter rope is generally sufficient, capable of handling around 5 tons. For larger vehicles like SUVs or pickup trucks, it's best to opt for a 10mm rope that can withstand up to 8 tons of pulling force. Avoid ropes that are too short—3 to 4 meters is the most practical length, as shorter ones may damage the tow hook. Before purchasing, check the quality of the end fittings; cast iron ones tend to crack, whereas forged ones are far more durable. After each use, remember to clean off mud to prevent rusting and weakening of the steel wires.
