The idea behind letting air out of your tires is that it allows the tires to ‘flex’ and not be so rigid. The key aspect here is that letting air out of your tires decreases the contact patch (it basically turns the tire into a ‘U’ shape, wherein only the side portions of the contact patch touch – as opposed to the entire contact patch). In actuality, this can decrease the friction between the tire and the ground. The key aspects to look for here are rubber compound, tread design, and tread depth. Winter tires, as Andrew points out, are a more aggressive tread that is designed to prevent snow from becoming packed in-between the tires’s grooves. Another key point though is that they are a softer rubber compound. And finally, as with any tire, it’s never smart to drive around on them once they’re worn out. This is extra important in the winter for obvious reasons. The list (of things to keep in your car) above is good, with the caveat that I would also recommend an extra pair of gloves, hat, and maybe an old coat. You never know what the conditions will be when you slide off the road or your car decides to break down. Corwin This is based on the common assumption that increased surface area results in increased friction. A study of Classical Mechanics shows that this is false… and gives us a logical explanation for #2 (the coefficient of static friction is always greater than or equal to that of kinetic friction). Not that anyone wanted a Physics lesson on a men’s blog, but there you have it… Nate Thank goodness I live in Texas and its 70 and sunny. We can’t handle this stuff down here, shuts us down completely when we get ice storms. Corwin Also missing from the list… your AAA card. Kyle A main difference between summer and snow tires is the tread compound. In winter temps the tread compound of summer tires basically turns to hard plastic and provide very little traction. Winter tires maintain their flexibility in extreme cold and thus provide more control.

For the one who have problems in getting vehicles stuck I think they should try it. http://www.tracgrabber.com/Testimonials-srk/ http://www.tracgrabber.com/ Muresan Mihai Nicolae you should try this Trac-Grabber rescue device: http://www.tracgrabber.com/Testimonials-srk/ get vehicle untuck from snow, sand and mud David Not bad, you are correct the point is to move, doesn’t matter if it’s forward, backward, or sideway. And go slow. But seriously, cardboard? Carry sand or cat litter? Do you guys not have traction aids in the US. That’s one thing to always have in your trunk in the winter. http://www.tracgrabber.com Jim Perry A great safety device for quickly and easily getting unstuck is the Trac-Grabber. They work great. http://www.tracgrabber.com Jim Perry There is a new product called Trac-Grabber that is perfect for one person to get their car unstuck from snow and ice.
