Tubular tires are expensive so it is wise to take measures which will
occasionally help lengthen their life span. One helpful procedure is
to give the sidewalls a cleaning with a sof t brush and soap water
then apply liquid latex(LBS).this milky solution protects the sidewall
fabric from uh moisture dirt road chemicals, ect. New tires come with
a coating but it quickly dissappears once they are ridden .
OVER IN EUROPE, a top racing cyclist may have dozens of tubulars down
in his basement, stored away like a good wine or you name it until
the passage of time brings them to full maturity-"I will ride no tire
before its time" Orson Wells might say. Really! The reason is that the
rubber of a newly manufactured tire is definitely softer and more
prone to punctures and wear than aged rubber. TWO TO THREE YEARS is
considered ideal, which means that smart riders will want to buy their
tires many months in advance of when they intend to use them. Until
then! The tires are stored in cool darkness, lightly inflated on old
rims(cheap) or hung loosely over larch rods. Once aged, the rubber
will show no mark when pressed with a thumbnail, nor will it act like
an e racer and give up little particles when it is rubbed."green
tires" will do both, and they will puncture more easily because they
tend to pick up and hold road debris, letting it work through the
tread.
Certainly all quality non-vulcanized cotton tubulars and all racing
tubulars constructed on a silk casing should be aged. Such tires can
cost up to $50 apiece(l984), and to ride them green is like throwing
money away. I remember...
Many tubulars in the moderate price range, for training and touring,
probably don't need aging. For one thing, it is becoming more and more
common for these to be made of nylon, which does not harden with
time[nylon stretches when cold, shrinks when warm] ON THE OTHER HAND,
the low cost rubber tubulars are machine made and the tread is
vulcanized onto the casing. The heat used in this process also serves
to harden the rubber, making the tires about as puncture resistant as
they would be hanging larch hung two years. It won't hurt to age
them(the writer's style is terrific and the '84 deserves a read),
however, and if you are able to get a deal(pssst) by buying in
quantity you should go ahead and treat them like expensive silks. IF
they came in a bundle, break it apart so there is no danger the tires
will come stuck together as the months go by.
[This is enough to get you into hiking!]
I remember an instance a few seasons ago when a team of riders from
florida competed for a month in the northeast. Among the equipment
their sponsor provided was a batch of top quality silk racing tires
with the cocksure model name"INVULNERABLE". They were anything but.
Having just arrived from the European factory, the tires sounded like
popcorn in races that took the riders over any road strewn with
gravel[and therein lies a tail?]
