Odd new kind of tire?

A) Why is the tire yellow? Does yellow withstand heat better? What's
the material? I've heard that adding carbon black to rubber will make
it harder and more wear-resistant.

B) Why does an indoor tire need a folding bead? Do riders on trainers
carry spare tires in their bike bags?

C) Why can't it be used outdoors?

D) Despite my doubts, is this $35 + shipping tire a godsend to riders
who use trainers? Will it outlast four cheap tires?

I've never understood this. My Conti Tempo track tubular with threads
showing after wearing it out on the track has been on my trainer for 3
years (average 60 miles/week). Pumped to 140 psi and pressed onto the
roller just enough so it can't be made to slip when holding the roller
stationary and turning the wheel by hand, it should last another 3
years.

I have seen trainers at peoples houses with a pile of rubber dust around
the roller and the tire squared off. Perhaps it's a function of too much
roller pressure and not enough tire pressure.

I ride rollers in the winter usually with 120 to 140 psi in the 23mm
tires and my big ol' 200lb weight smushing them into the rollers and
don't see any noticeable tire wear although the tires do seem to pick up
a layer of silvery black on the tread from the aluminum of the rollers.
After lots of miles the rollers still have machine marks in them so I'm
not worried yet.

Yellow tires, not the new black, but the next psych job.

The thicker the tread the more heat is generated running on small
diameter rollers that pretty much like running over a continuous
cattle guard that causes far more flexing than riding on roads. The
yellow tread has neither carbon-black nor silica, so it is a sure wet
road hazard and a tire that would wear rapidly.

Clement made a similar tire that had red rubber intended for TT
racing, the absence of carbon black giving lower rolling resistance
but also not to be used on wet roads. Most of us had the opportunity
to lose traction and verify that feature.

A tubular, highly inflated, with thin tread has all the right
characteristics for small diameter rollers. In the days of yore when
there were roller races, the rollers were about 0.5m in diameter it
made little difference for reliability what tires were used except
that tubulars of that era had thin treads and casings anyway.

Why does any tire have a wire bead? Is it cheaper to produce? Or more
reliable?

I just retired a Contin Sprinter that I didn't trust for the road
that'd been on my trainerbike for years. No apparent tread wear, but
the case started failing recently.

Dear John,

Usually, the foldable Kevlar version of the same tire model is usually
lighter, higher-priced, and higher-rated for inflation.

A quick look at Performance confirms two out of three of my claims.
The Kevlar Forte GT2 costs more, weighs the same (?), and is rated for
higher inflation:

Forte GT2 Wire, 105 psi, 295g for 700x25, $12.99 on sale for $6.98:

http://www.performancebike.com/shop/profile.cfm?SKU=4780&subcategory_ID=5420

Forte GT2 Kevlar, 125 psi, 295g for 700x25, $17.99 on sale for $9.98:

http://www.performancebike.com/shop/profile.cfm?SKU=4664&subcategory_ID=5420

Let's try Continental. Two out of three again, the Kevlar version
being lighter and more expensive, but same inflation rating:

Continental Ultra Road Race Wire, $34.99, 270g, 120 psi:
http://www.performancebike.com/shop/profile.cfm?SKU=22699&subcategory_ID=5420


Continental Ultra Road Race Folding, $41.99, 220g, 120 psi:
http://www.performancebike.com/shop/profile.cfm?SKU=22698&subcategory_ID=5420

As far as I know, the tread and the casing are much more likely to
fail than wire or Kevlar beads. The bead is protected by the metal
rim.

Kevlar beads are supposed to be stretchier and easier to mount and
remove, but the stretchiness makes them less suitable for older rims
that lack the hook profile.

Cheers,

Carl Fogel

I find no observable reason for this tire to exist. I'm just running a cheap
Maxxis road tire that shows no additional, excessive, obvious wear from it's
life on the trainer.

Even at $35, iot isn't cheap. How about a $14 wire ultra sport Conti
for the trainer?

insufficient roller pressure is the usual culprit. if there's slip
between the roller and tire there will be a lot of tire wear. there can
also be slip if someone does hard surges.
 
I've melted tires on my trainer before. That might not be a problem with
$10 tires. Melting $50 ones would be painful. Melting a $25 tire was
painful.

It's yellow make it obvious that you're not supposed to ride it outside?
Yellow won't leave a black smudge on your trainer?

Easy storage?

It has to be a low demand item, so how could the manufacturer drive up the
profit? People are willing to pay a lot more for Kevlar beads. Maybe that
helps consumers justify the price.

It's probably very slippery in the wet, like the Umma Gumma.

Maybe. Or maybe it won't leave rubber on your trainer.

Sounds like marketing spin to create demand where there is no need. Not
all features are advantages.

They didn't get the mustard out.

Of course, but as the Keeper of the Yellow Air Pump, you should have
an inherent understanding of this basic law of the snakeoiliverse.

Continental's proprietary compound, Undisclosium.

Yes, but this isn't just ordinary rubber...

>B) Why does an indoor tire need a folding bead?

Because it's Cool. (And doubtless because this makes the tire cheaper
to ship.)

Silly, of course not. They keep them in the wine rack.

>C) Why can't it be used outdoors?

Because that would be Wrong. (There may be other reasons, but if
they're telling you this up front, it's probably a good bet that
there's something about the tire's compound or construction that will
make you wish you had followed the advice.)

>D) Despite my doubts, is this $35 + shipping tire a godsend to riders

No, it's sent from Conti, via Nashbar.


>Will it outlast four cheap tires?

The discerning and satisfied consumer will ensure that no other
admission is made; the disgruntled will deny the possibility.

Would those be from a certain borough of NYC, perhaps?

It doesn't, but the price premium is small and stocking, shipping and
storage is easier. Actually, the last person I saw buying these in my
LBS was taking them abroad on a diplomatic posting...

>C) Why can't it be used outdoors?

It can, if you put your trainer out in the yard. Just don't ride on
the road, or you'll fall off on the first wet corner

>D) Despite my doubts, is this $35 + shipping tire a godsend to riders

Probably not, but fitting tyres is a PITA. Over here, I paid <GBP30
for two tyres, which is only twice the price of something cheap and
nasty. I'll let you know when they wear out, but it might be a while
as I spend less than an hour a week on the rollers

And I have no doubt that Conti chose yellow because that's the
winner's color in the TdF.

Dear Kinky & Werehatrack,

Taxi drivers and schizophrenics prefer yellow for other reasons.
