With winter officially announcing its presence last night, I
am recalling a thread a few weeks ago about using lower tire
pressures to drive on ice.  Can anyone reiterate the details
of that for this "snow & ice newbie"?  I already have some
Z-chains (they go on fast & fit great!), but I'm curious
about the tire pressure technique.
