General rule: front tread points forward; rear, rear.

Oh? How do you figure that?

Actually, it makes no difference, but if you want to be aesthetically
correct, the chevron of both tires treads should point forward when viewed
from the top.

MTB enduro/cross tires run on more pavement than dirt go on
backwards-point to rear or moderate use point to rear on rear to front
on front.
Conti TT's so indicate.
i tried the TT's both ways-more stability under a commuting load with
the rear points pointed to the rear, maybe faster both pointing front??
definitely slipperyerer in the rain.
notice Conti TT went to the complexity of using duh? i duunoo what
they're called-
prongs of rubber run circumferentially below the tread contact
surface-when riding in rain the prongs thro water off before water
runs over brake surfaces
so Conti spent time thinking about this
and it seems to work

I'm forgetting ATM what exactly the Marathon tread looks like, but
mount them so that any arrow- or v-like shape to them is pointed in the
direction the bike moves for the front tire, and the opposite of that
on the rear tire. This may be sort of a tricky thing to figure out for
Marathons - if memory serves, most of the pattern you'll be looking for
will be part of their continuous center tread.

This isn't going to matter very much, if at all, for these tires, or
any tire like them. The reason it ever matters is this: say you're
riding off road and you have typical MTB tires with some kind of
chevon/arrow/v-shaped aspect to their tread. For such tires being used
in front that don't have any orientation marking, it's the rule that
the "V" should point in the direction you roll. The reason for this is
that on the contact patch of the tire, the part contacting the ground,
the open end of that V will then be positioned in a way that will
improve your front tire traction when you're using your front brake.
Hopefully this is pretty easy to visualize.

The same effect occurs on rear tires during both braking and pedalling.
Some people say you should mount rear MTB tires without orientation
labels the same as the front, and some say the opposite. I think that
in most cases, the opposite makes more sense, but there are probably
exceptions to that.

For completely smooth tires, even those with a superficial V in their
tread, none of this matters at all really. There are some people who
say none of this ever matters at all. In your case, the idea is that
even though these are primarily road tires, mounting them this way
might make some kind of difference when you're off-road.

i'm back.
ok-
shoveling backwards for the rear tire
shoveling forwards-in the direction of motion-WHICH IS OPPOSITE THE
ROTATION DIRECTION
gives precise changes in direction (or does it?-never tried
it that way)
shoveling backwards on the front will be in
opposition to the function-change of direction.

Usually, if a thread is directional, if you mount the lable on the
drive side, the rotational direction is correct. I use the Marathon
and it has labels on both sides and I don't see why it should be
directional. I still don't understand why normal road tires should be
directional anytime.

Unless my temporay flush and concomittant stupor have dulled me enormously,
you will find tiny little arrows on the tread (between sidewall and center
stripe) to direct you how to mount them.

Although alternative postures can be entertaining.

Directional tread is an old saw that makes it's appearance whenever
some marketeer believes the public has forgotten the last time it
appeared. The motorcycle folks have been spared of this ritual by the
acceptance of slicks, that by their nature are the epitome of non
directionality. Bicyclists have not yet gotten there. For dirt
tires, I think John Deere has the solution for wheels that spin,
ejecting mud to the sides, but this is not a problem with bicycle that
don't work in the wheel-spin mode.

Other than a durable casing and long wearing tread, what do you expect
from the tread pattern on these tires? Drop by the local motorcycle
meeting ground and look at the tires.

dissent: tractor tires cost $$$-placing them in shovel backwards mode
could quickly wear the tread out given the various surfaces a farm
tractor need traverse.
a worn tractor tread gives zero traction.
and the farm tractor steers like a porsche-from the rear wheels at
speed and a farm tractor is at speed all the time-GRIP!!
we're back to the brake balance/oversteer/understeer/gary nixon
question.
anyway, i tried it opposite of the Conti TT directions-IT'S SLIPPERY!!

On that page:

# Why are there so many tires with direction arrows?
#
# In road tires, a tread with a rolling direction generally provides a
# slight reduction in rolling resistance. In addition to this,
# aesthetic considerations can also be important.

# Off road, rolling direction is far more important, as the tread
# ensures optimum connection between the tire and the ground. The rear
# wheel transmits the driving force and the front wheel transmits the
# braking and steering forces. Driving and braking forces operate in
# different directions so this is why certain tires are fitted in
# opposite rolling directions when used as front and rear tires.

# There are also treads without a specified rolling direction.

If you believe that, then you need to think why farm tractor tires
have chevron tread and why they have a preferred direction. As I
said, marketing types try to make a bridge between farm tractors and
humans on MTB's, a macho image for sure. That is not the way it
works. Bicycles don't operate in wheel spin mode... even in dirt.

There's something wrong with the BS on that web site. Front and rear
tires on motorcycles are not interchangeable yet the writer makes dire
unsupported claims about direction of rotation when switching tires
that way. Maybe you can explain what the casing structure, bias ply
and radial, has to do with direction of rotation. Besides, what's all
the talk of tread patterns. I just mentioned that motorcycles today
have gone entirely smooth except for widely spaced tread depth
grooves. Being round in cross section, they disperse water better
than any tread pattern could. Just like the wheels on 747's that land
on wet runways at over 100mph.

The smooth areas between grooves is several times as large as the
entire rubber surface of a bicycle tire. Don't repeat this BS. The
guy even drags in hydroplaning, the bugaboo of bicyclists who stay
away from slicks.

I doubt it has much to do with ejecting the mud to the side, instead it
has to do with making the traction tires self-clearing of mud. That is
a small but important difference. I have also heard that on
non-traction wheels you can get a marginally better tread life if you
mount the tractor tires backwards (i.e. where the two ends of the
chevron hit the ground before the point. I think you are correct about
this not being an operational factor on bicycle wheels. However, I
would had thought someone would have studied which direction throws the
least water in your face on wet roads.

OK I finally figured it out.
