6 Myths about Winter Tires

If you think you don't need winter tires, think again. Here are six reasons people give for not switching to winter tires, and why those reasons are wrong.
Myth: Because my vehicle has 4WD that delivers great traction, I don't need winter tires.
4WD and AWD systems do provide optimized power transmission delivery, but they provide minimal assistance in transverse handling and braking. The weight and higher ground clearance diminish the stability and control of these vehicles. With winter tires, you optimize traction during all maneuvers including acceleration, braking and turning.
Myth: I don't need winter tires with ABS.
Advanced electronic systems such as ESC (electronic stability control), TCS (traction control systems), and ABS (antilock braking) are designed for vehicle stability, power transmission and controlled braking. But they aren't substitutes for optimized traction grip during all types of winter driving maneuvers, including braking, acceleration, and handling.
Myth: Because it snows or is icy only occasionally during winter where I live, all-season tires are my best choice.
Although you can use all-season tires in a moderate winter environment, winter tires provide the best cold weather performance below 44 degrees F. That includes wet and dry in addition to snow/ice/slush surfaces where greater tread flexibility gives better grip.
Myth: The braking distance is the same whether my vehicle is equipped with winter or all-season tires.
The braking distance of a winter tire compared to an all-season tire, depending on speed and road conditions, can be up to 10 percent shorter, or two vehicle lengths.
Myth: The outside temperature doesn't affect my tires' air pressure.
Proper inflation is a critical, and you should check it checked monthly. For every 10 degree drop in temperature, tires lose one pound of air pressure — so it's especially important to check air pressure after the first frost. Also, properly inflated tires ensure optimum fuel efficiency and prevent irregular and premature wear.
-baidu 1point3acresMyth: Winter tires are more expensive.
The cost of winter tires is generally about the same as replacement tires, and can be lower. And when you consider that the months your winter tires are on your vehicle are months that your regular tires get no wear, the overall cost of buying replacement tires is the same, and the benefit is that you can drive more safely in treacherous winter weather.

MA那里必须雪胎吗？
今年大雪的那天开了在外16个小时，高速10个小时，经验大涨，雪天开车也老实多了。庆幸自己轮胎换了没多久。

12月23号时又有中国学生出车祸了...

这段有误导性吧，换下来的轮胎放着不用也会老化的。

我看MITBBS有个贴子讲的就是这个，很久不用的胎（~10年），老化太严重，差点出事。

通宵做实验，然后早上5点一出实验室大门发现外面大雪。但是已经说好要开车送人。将近俩小时到费城机场，被告知航班取消，如果想在一周内回国必须当天赶到Newark。于是又开了三个多小时到Newark。在机场等了四个小时确认他们可以上飞机回国，再开始往回开，NJ Turnpike堵得一塌糊涂，曾经在一个service center堵了两个小时，在另一个service center睡了一个小时，实在扛不住。晚上到了家已经9点了。从此之后下雪天再也不想送人。

前些日子去Austin的时候赶上暴雨, 头一次见到那么大的雨, 高速上连路都看不见了, literally, 只能看到所有车都在打双闪, 赶紧找路下高速到边儿上等着, 雨稍微小了些才继续走, 路上3个小时, 雨也下了3个小时...太点儿背了..

i think the article means to alternate winter tires and all season tires, so the idle time is really like 6 months....
