Cars on ski slopes, 2 WD, 4 WD, and 4x4 snow tires rule

submitted by SFOGuy

9 years 11 months 1 week ago

We're all going to be going out into the cold in our holidays-- Worth a few moments to review:
The're Brits, so their use of freedom units is inconsistent but it's quite understandable...

2WD and 4WD cars on street tires. Not that impressive.

2 WD on snow sticky tires; whoa, nice improvement

4 WD on snows sticky chunky snow tires---all the way to the the top of the slope!

Connects to this video in which the STOPPING powers of 2WD and 4WD on regular versus snow tires are reviewed, Worth seeing and putting on winter tires is you're hankering for Tahoe, Seattle, Deer Valley, Aspen, Jackson Hole, Vail, Sun Valley----or more mundanely, Chicago, Cleveland, Buffalo, Detroit, New York, Boston---or Anchorage.

Goes into some trouble to explain the issues of treat compound, drive train, and sipe (this word apparently means the cut pattern in the treat block) pattern for aggressive treads---as well as snow-to-snow stickiness with snow tires.

Follow up piece on braking/stopping in snow...
