Just wondering if you still find it necessary despite the AWD.
I just get one set of tires to use in all weather conditions. I don't
get [near] baldy tires. The tread is needed for grip when driving in
snow (not ice) and to channel out water when driving in rain. I don't
put on fat (wide) tires due to the plowing effect in snow. Skinnier
tires handle better in deep snow. I just go with all-weather tires and
keep the overall profile the same as for the standard tire & wheel to
eliminate any problems with tire travel. Of course, these tires are
used for a wide range of driving conditions on roads and not at the
extremes of pushing the SUV to its off-roading limits.
You may need knobby snow tires if you are continually driving on
unplowed unpaved roads or making your own roads. You didn't specify
WHICH Subaru model you are asking about. Some have more ground
clearance than others hence are more util for off-roading. Outbacks
have 8.4-8.1" ground clearance, Foresters have 7.5", and the Legacy only
has 5.9". More ground clearance is a boon to off-road adventurers but a
bane to roadgoers (due to exaggerated "dancing" due to more roll, dive,
and squat in cornering or avoidance manuevers).
Few SUV owners actually beat their beast to test just how nasty an
off-road experience they can survive before calling the nearest farmer
to yank their vehicle out of the muck. Even rarer are roadgoers that
actually test their vehicles and practive regularly to get used to when
understeer turns into oversteer, making skid turns or deliberate
spinouts of repeatable rotation, when to crank the wheel into the skid
and just the moment when to crank it back, and so on. Their "practice"
is their everyday driving to and from work, not performance practicing
to push the handling for emergency manuevers or racing.
If it's your intention to actually go hard off-roading then you need to
get tires that are appropriate for the terrain where you intend to play.
You never mentioned HOW you will be using the vehicle for the majority
of its use and when, if ever, you will be pushing it beyond your
everyday roadgoing use. For example, snow on roads is a different
situation than snow on unpaved and uneven roads, like forest logging
paths.
