When to use Snow Chains
While many people today believe that snow tires or all season tires are all that they need, there are some extreme conditions that require a little more attention. Snow chains are driving accessories that we hope we never have to use. They are, however, sometimes vital. Deep snow, ice, and slush are all good reasons to invest in a set of chains.If you live in mountainous regions, then you probably already know that when there is snow and ice on the roads, it is time to break out the snow chains. In fact, in some states, it is considered a mandatory measure for traveling in some areas. You do not need to travel on slippery or snow covered slopes more than once to know that anything that provides traction is a plus.Even on flatland, there are times when snow chains are crucial. In remote regions, where long stretches of roads may be snow covered for a major part of the winter months, getting stuck along the way is not an attractive option. In these areas of the Midwest, where dry pavement may seldom be seen during the winter, snow chains are standard equipment.In the northeastern states, not having snow chains and, as a result, skidding off of the road, or otherwise causing a traffic problem, can result in a citation.Snow chains are used in different ways on different vehicles. Four wheel drive vehicles need chains on all four tires, front wheel drive need chains only on the front, and rear wheel drive, on the back. Altering this arrangement in any way can cause an imbalance in handling that may defeat the purpose for which they were designed.It is just as important to know when to take the chains off as it is to determine when to put them on. Once roads, and parking lots have cleared to the point where clear pavement is visible, chains should be removed. Driving on dry pavement with chains not only damages the pavement, it decreases traction. Under dry conditions, chains prevent tires, and the tread, from reaching the ground, causing skidding during stops, starts and turns.Overall, the rule of thumb is that whenever conditions are extreme and all roadways are covered with snow and ice and hazardous, snow chains should be used. In fact, laws governing their use in most states, use these criteria when determining when and where they are permitted.
