The (old) Agilis 61s (185R14) on my syncro are "all weather" and have
"M+S" on the sidewall.  But not the snowflake that marks true winter
tires.  They are fine on the syncro.  I'd never think of chains around
here.  I used to use chains frequently on my '81 air-cooled with the
same tires.  Cable chains, for sure.  Any radial tire likes cable chains
better than "chain" chains.

for info from Montana and Oregon.  Montana is like Colorado--M+S is
OK--because the snow is like ours--dry.  Oregon wants chains when it
is really bad--or tires with the snowflake designation.

My syncro manuals state it is preferable to use chains on all four
tires, but if only two, then the rear tires.  So you could buy a
set of cable chains for your rears as protection.  I would head out
with my M+S tires and figure I'd be fine.  Again, stopping is the
problem and you have to drive accordingly.
