Are Snow Chains Useful for Cars on Icy Roads?
2 Answers
Snow chains are useful for cars on icy roads, but different types of chains offer varying levels of traction. For large trucks, iron chains are the best choice when the ground is icy and slippery, while rubber chains are suitable for private cars. Currently, the more common types of snow chains include iron snow chains, polyurethane (nylon) snow chains, and rubber snow chains. There are also some precautions to note when installing snow chains. Snow chains should be installed on the drive wheels. For four-wheel-drive vehicles, all four wheels need to be equipped with chains. For two-wheel-drive vehicles, chains only need to be installed on the drive wheels, though installing them on all wheels provides additional stability. Additionally, after installing snow chains, drivers should control their speed during driving, remembering to slow down and drive cautiously. The speed should ideally be kept below 40 km/h, and sudden acceleration, sudden braking, or sharp turns should be avoided.
Snow chains are indeed highly effective on icy roads. As someone who has long studied automotive safety, I've reviewed substantial data proving they significantly enhance tire traction. When roads ice over, tires tend to slip, but the metal or synthetic materials of snow chains bite into the snow and ice, providing additional friction that reduces the risk of vehicle loss of control. However, proper installation is crucial—they must be tightly secured on the tires, neither too loose nor too tight, otherwise their effectiveness diminishes or they may damage the tires. I recommend choosing high-quality chains, such as those with rust-resistant designs, and paying attention to driving speed, generally keeping it below 30 km/h. Don't assume they're a cure-all; if the ice is too thick or the slope too steep, other methods may still be necessary.
