lively, low rolling resistance 700C road/off-road tire?
Earl Grey
I am running IRC Mythos XC Slick 42mm tires on my Sam, and am looking
for a dual purpose tire that leans a little more towards paved road
performance (let's say 75% road use, 25% dirt, but with some technical
stuff). The Mythos "Slick" is anything but slick. The center knobbies
are shorter, but of varying height, which creates a noticeable buzz on
pavement, though they grip great on hard dirt.
I want a lively tire with low rolling resistance, and I don't want/
need puncture protection (I hardly ever get flats, even on plain Jack
Browns off-road).
Does anyone have experience with the Marathon Cross versus the
Marathon Extreme? Seems the Extreme might be the way to go, but I
wonder how the Cross compares. Extremes are wider (40mm versus 38) and
folding, so what do the Crosses have in their favor?
Cheers,

tire in my experience. Good at rolling through just about
everything. But not like the smoother Marathon Supremes. It also
does buzz a touch on the roads. Not enough to annoy me, but enough to
be noticed if riding near others with regular road tires. Do plan to
use it as the main tire on my commuting/occasional touring bike.
Haven't used the Extremes, so can't compare directly.

but can only compare to the XR that used to be in the rear. The
reduction in weight is noticably large and the ride is much smoother
quicker to spin etc. It is not close to the JB in pillow like
smootheness, but definately passible for around town errands, and that
includes 20 mile round trip farmers market runs. The buzz is barely
there too, compared to the xr on an edge or the Panaracer fire crosses
I also run from time to time. Then there is the dirt!!! the extreme
holds in almost as well as the firecrosses, but without any of the
penalty on the road.
Every time I think about putting true slicks on the Rawland, I hold
off and figure I would be better served selling the firecrosses and
buying another extreme, and calling it done.

they are great in the dirt but a little noisy on pave. I'd like
something with less rolling resistance on road but workable on dirt,
and maybe the Extremes are the way to go... Hard to find in the 40
width, only one online retailer has them and $65 a pop... are they
really worth it?

I live in an area that seems to be paved with broken glass, goathead
thorns, nails, screw, etc... Both of the above tires have performed
exceptionally in the fight against fixing flats. I may loose a minute
or five per hour compared to my bikes with slicks, but not too bad
really. The XRs are bulletprof, but heavy and tend to wash out in
turns if I do not keep my speed in check on the dirt. THe extremes
make up for these short comings.
Take a look at wallbike.com I have had great service, and they do a
decent job of keeping things in stock

Challenge Grifo XS. killer tire.

fast in tests. Fine for most off-road and I've used the 35mm on the
Romulus in singletrack, gingerly but successfully.

The are light for a knobby of that size and roll great on pavement-
you can hear a tiny buzz but you can't feel it at all and the rolling
resistance is low. They even corner great on pavement, i find they
don't have as much "side knob dive" as other similar tires. And they
provide plenty of confidence off road.
I've ridden both the 700x32 and the (no longer produced) 700x40
versions, and they're both good. In the absence of a light, true
slick around 40mm, the 700x40 version is by far the most comfortable
tire i've ridden on the road.

The WTB All-Terrain looks a bit heavy (630g in 38mm). Jeremy, do you
know about the Marathon Supremes and Racers? Slicks in 40 and 38mm,
respectively. Seem worth a try, though I haven't.
Grifo XS looks nice, but too narrow, unless it runs incredibly wide.
Marathon Extremes seem to be in the lead, but:
Has anyone tried the Specialized Borough XC Pro 45mm? (Claimed weight
425g, with side knobbies): http://tinyurl.com/y9j9wvw
My guess is that they would corner worse on pavement but better on
dirt than the Extremes. Look promising. Can the Specializeds be bought
online in the US? (The stores I found it at say store pick-up only,
except one store in Germany.)

nah, the Grifo XS definitely doesn't run wide - it's barely 32mm. but
it's fast tire on all kinds of off-road surfaces and it's very lenient
with psi, which is more important than nominal width in my
experience. personally, i wouldn't ride it on the road, but it sounds
like you want at least a little bite in the tread profile.
is the 25% dirt really knarly or what? the marathon extreme (and some
other tires considered here) seems very aggressive if you're looking
to spend, say 90mins out of 120mins on the road and want a lively,
fast rolling tire.

(steep, deeply rutted jeep trail with a very variable amount of gravel
and sharp, fist-sized rocks sprinkled about, in an attempt to fill the
ruts, probably). But in order to ride those sections, I'd have to go
50-60mm, I think, so I am happy to keep walking those 50 meters. So I
am hoping for similar dirt performance as the Mythos, but less buzz on
the road.
There really seem to be two approaches to this kind of tire:
1. Marathon Extreme style: short, very large "knobs" with relatively
narrow grooves in between, with a fairly round profile.
2. Specialized Borough SC Pro style: smooth center section with
relatively tall and widely spaced side knobs.
Presumably style 1 does better in on-road cornering, while incurring a
weight penalty, but can anyone comment on other differences between
the styles? Does style 2 really improve off-road cornering? Note that
I am not really concerned with going fast off-road, I just want to be
able to ride through some relatively technical stuff, while still
having a compliant and smooth ride on the way there.

listing a whole bunch of other tires. Ritchey ZEDs get high marks, but
are no longer made (?), and probably don't roll that well on pavement.
The Specialized Borough XC Pro 45mm seem to run very narrow (acc. to
one poster), making them much less attractive, IMO.

i feel like this is where 650b really shines - fat "road" tires that
can be ridden at very low pressures for off-road comfort and
traction. it really makes for a great transition from pavement to off-
road.
seems like everything in 700c that is bigger than 35ish gets really
aggressive, or is a stout commuting/trekking tire.

Yes. Transition == note the sign, keep right on truckin', say "Man,
those Hetres are simply amazing!".

Exactly.

commuting and found them great on the road. Didn't really ride them
off-road.
The Extremes have no buzz on the road and rolled great. Right now I
think I prefer them. Still have a pair of the Borroughs 32;
Armadillos, I think. Almost new, still a long life left in them. You
can have them for $30 + shipping. I'm traveling now but can confirm
when what version they are when I get home on Saturday.
