Tyre Warmers, Tire Warmers, Termocoperte, Couvertures Chauffantes, Calientadores,
Reifenwarmer, Tyre heaters, Tire heaters, Tyre blankets, Tire blankets... No matter how
you say it, Tyre Warmers have four main functions:
- To pre-heat the tires for greater adhesion
- To enable longer tire life by reducing cold shredding
- To help the rider get better starts
- To improve rider confidence
1. Greater Adhesion
It takes a long time to heat tyres so they will function properly
by riding the bike. Compound Tires like Racing Slicks and Treaded
Road Tyres (not including Full Wet Racing Tires or Trials type tires),
become sticky when they reach 'Operating Temperature'. Operating
Temperature usually ranges between 85 - 100 degrees Celcius (185
- 212 degrees Fahrenheit). This temperature is reached due to the
tire working on the road / track surface or by being heated close
to 'Operating Temperature' using a Tyre Warmer.
Until tires are 'up to temperature' they will be inflexable,
have a hard surface and a reduced contact patch, they lack
grip and sliding is the result. Depending on track temperature
and the weather, it actually takes 4 - 6 laps to get tyres
to 'Operating Temperature'. That's 4 - 6 laps of less than
optimum traction, less confidence and greater risk. In some
cases, that's the whole race or over half a Track Ride Day
A 'Good' Tyre Warmer will heat tyres up to a temperature just short
of 'Operating Temperature'. Too low a temperature and the tyres
will 'Cold Tear' too high and the tyres will harden and go off.
We deliberately say 'Good' Tyre Warmers because most Tire Warmers
actually fail do the job right.
2. Longer Tire Life
When a tire starts out cold and is worked on the road / track
surface the temperature rises, as the temperature rises the surface
rubber is removed at a faster rate than when the tire is up to operating
temperature. The discarded surface rubber forms little balls at
the working edge. This Cold Tearing or Cold Shreading reduces the
life of the tyre and is avoided when using a Tyre Warmer that pre-heats
the tire to the correct opperating temperature.
3. Better Starts
With grip, feel and feedback available, the rider can enter turn
one with the confidence that when they lean the bike into the turn
the front will stick and the rear will grip. When the front sticks,
the bike will turn and the rider will roll the throttle on. When
the rear grips, the bike will drive out of the corner and the rider
has put his or her competition behind them when it is easiest to
do so. Even if you leave the Pits with tyres heated by Tyre Warmers,
there is no guarantee that you will have hot tyres at the start
line. Our research shows that tires loose temperature as soon as
the Warmers are removed. As you ride the gridding or sighting lap,
tires are being made colder with Track Contact, no ammount of weaving
can compensate. In the end, depending on the Tyre Warmers you have
used, they have been of little, if any benefit to you.
The heat loss from the tyre is caused by the tyre and rim assembly
not being properly heated. When sufficient temperature is stored
in the rim, there is a 'Temperature Reserve' for the tire to draw
from as it cools. A good Tire Warmer will not just cover the tire's
working surface, it will protect side walls and 'pump' temnperatture
into the rim.
Rider Confidence in the Machine is vitally important. Confidence
is psycological and is the attitude of the rider to the way
he or she rides the bike. Confidence is however influenced
by the level of grip available, the ability to turn the bike,
accelorate the Machine progressivly and control the bike with
ease. Without these influences being positive and supporting
the rider, the Rider's Confidence is lessened or at least
Without Confidence the rider is often just trying to survive
riding the bike. The rider is tense, holds the controlls too
tightly, uses stressed and 'jirky' imputs to keep control
and is not smooth. If this does not sound familier, it is
possible you may not be aware of what is going on when you
ride as your attention is focused on suvival.
Rider Confidence in the Machine is what Suspension Set-up is all
about and you know how much importance is placed on having the 'right
Suspension Set-up'. Rider Confidence is also one of the main reasons
Tyre Warmers are essential. Tyre Warmers prepare the tyres so that
the rider can go out hard and ride with confidence and control,
in racing terms if you start out faster, you will end up faster.
Sportsbike have manufactured Tyre Warmers since
1996. Through extensive development and by working with many of
the world's best riders and Teams, we have been able to develop
a Tyre Warmer that works. Sportsbike has developed a design
of Tire Warmer that considerably reduces the rate of cooling and
enables a tyre to be at a higher temperature at the start line.
Sportsbike Tire Warmers are designed to help tires to be
hotter in turn one... the rest is up to the rider.
