How Many Snow Chains Should Be Installed for Driving on Ice and Snow Roads?
2 Answers
On ice and snow roads, snow chains should be installed on all four tires. Installing them on all four tires provides relatively stable traction, whereas installing them on only two tires can easily lead to fishtailing, compromising driving safety. Snow chains are made of steel or rubber and serve an anti-slip function. They come in two types: one is a pre-connected cover-like chain, and the other consists of several separate cross-installed chains. The separate chains are simpler and cheaper but less convenient to install compared to the former. Precautions for Using Snow Chains: Install the snow chains before setting out, not after encountering icy or snowy roads; park the vehicle in a safe area before installation or removal; do not install snow chains on a flat tire; choose snow chains that fit the tire size; after installation, drive at low speeds and avoid sudden acceleration or deceleration; remove the snow chains promptly when driving on roads where they are no longer needed.
When driving on icy or snowy roads, I always recommend installing snow chains on all four wheels. This maximizes traction and stability, as icy road surfaces are extremely slippery. Installing chains on only one or two wheels can easily lead to loss of control and skidding, especially during turns or braking, which is particularly dangerous. Once, I only installed chains on the rear wheels while driving in the mountains, and on a gentle slope, the front wheels lost traction, causing the car to sway uncontrollably—I nearly hit the guardrail. Since then, I’ve insisted on installing them on all wheels. When installing, don’t forget to check the tightness of the chains. If they’re too tight, they may damage the tires; if too loose, their effectiveness is reduced. Also, regularly inspect them for wear and replace them promptly to ensure safety. Additionally, cold weather shortens the lifespan of chains, so it’s best to carry an extra set for emergencies to avoid issues mid-journey. In short, safety comes first—don’t cut corners or save money by installing fewer chains. The potential losses from an accident far outweigh the cost of a few chains.
