Motorsports Motorcycle Tire Warmer Set - Black
These are the newest
spec tire warmers from Graves Motorsports. Fresh off back to back Superbike
Championships with Josh Hayes and the Yamaha R1! Graves motorsports introduces
there new spec of tire warmers available to our customers. Graves Yamaha
has a serious pedigree in racing on the pavement and everyone knows you
need hot tires before entering the race track at speed.

Chuck Graves team
owner and former Champion himself has this to say about the Graves warmers.
these warmers with effectiveness in mind. When the tire is hot before
subjecting the rubber to the heavy loads created by the G forces of lean
angle, power output and extreme braking we get longer lasting performance
out of our race tires. Heating the rubber all the way through to the rim
over the desired time frame at the correct temperature is essential to
the consistency of feel that the rider has over a greater number of laps
allowing our team to get better feedback from the rider to fine tune all
the other areas of our race bikes. No team or track day rider should be
without these. You only get so many laps a day and we want to make the
best use of every lap" - Chuck Graves Team Owner; Team Graves Yamaha

- Featuring all
new Neoprene Side Panels and Graves Motorsports Gas Station Logo!
- Hot tire pressure
is more important than ever. These neoprene sides additionally insulate
the tire and wheel, and help block wind blowing across your rims. The
elastic stretch also provides a smooth fit!
- The most durable
warmers in the paddock are easiest/fastest to take on and off and have
raised the bar once again.
- Fast and effective
heat up, even on cold days- Temperature set at 80c
- Melt-Proof inner
liner (with heat sensitive dye to show mis-use or mal-function)
- Operating Light-
RED shows when heating and GREEN when full temp is reached
- Dupont Nomex/Kevlar
Insulation to keep the heat in and set Hot Pressures- Heat the entire
carcass deep down
- Built Tough - Codura
Exterior & high impact temperature controllers, full coverage Heating
- QUALITY & PRICE
- designed & built in the USA, these warmers are 2nd to none and
is one of the most economically priced!
Benefits of Tire Warmers
- Most racers and
track day riders want tire warmers to avoid cold tire crashes and to
go fast right from the green flag.
It is true that these are two clear advantages of using Tire Warmers,
but there are other benefits that are equally important. A Tire Warmer
provides the ability to tune and manage tires in the paddock beyond
the grip offered on the opening laps:
Go Fast from the Green Flag
Set Hot Tire Pressures in the Pits
Avoid "cold tearing" tires
Save "Heat Cycles" by keeping tire warm in between sessions
Tires last longer
Hot rubber grips the track surface better since not only does the coefficient
of friction increase, but the Tire’s ability to form the track
surface through "mechanical keying" is increased
Set Hot Pressures
- Tires will increase
in pressure about 20% on the track (ie: 30 to 36 psi) which makes a
huge handling difference. Graves'Tire Warmers will get your tires surface
AND carcass into the proper temperature range (same as you’ll
see on the track). Without Tire Warmers 6-8 laps would be needed to
get a tire to its proper "hot pressure".
Many of the current race compound tires are "low pressure"
tires with psi recommendation of around 22-24 psi. These tires are more
sensitive to being at hot pressure before they work properly.
Set the Tire Warmers to the temperature you anticipate seeing on the
track, allow them to "heat-soak" for an hour and set the Hot
Pressure. When you hit the track, there will be minimal change. Getting
your Hot Tire Pressure set on the Tire Warmers gets you going right
Avoid "Cold Tearing" tires
- Taking a 70 degree
tire and pushing it hard on the track will increase the very outer surface
of the rubber in a couple of laps. However the rubber 2-3 mm down is
not yet warm and not as elastic. This causes the outer rubber to grip
the track surface and underlying rubber to rip or tear. This shredded
look or graining once developed in the tire almost never goes away and
basically ruins the tire. By pre-heating the rubber, cold tearing is
Save Heat Cycles
- When tires are
heated & then cooled, a change occurs that can be seen, measured
and felt. On some tires you can actually see a blue haze form over the
tire as some "oils" migrate to the surface and oxidation occurs.
On other tires one might observe much drier grayish haze depending on
individual tire composition. Putting the tire though these hot to cold
cycles reduces the tires grip, hardens the rubber and reduces its useful
life. A tire warmer can keep tires hot or simply warm (for longer periods
of time) between track sessions and reduce the amount of heat cycles
a tire goes through. If the tire is to see more than one track session
it makes sense not to allow that tire to cool all the way to ambient;
this can extend how many sessions the tire can perform at near maximum
grip. By operating in this manner the tire’s grip life is increased.
Tires last longer
- Taking tires from
ambient temperature and bringing them to race temperature on the track
may take from 3-6 minutes depending on the machine, track and rider.
Aside from giving up speed during these opening laps, it is truly too
fast to heat the tire in an ideal manner. For example on a 75 degree
day, the rider gets the tire surface hot in 4 laps, which takes 6 minutes.
This increase of 100 degrees in such a short amount of time actually
"heat shocks" the tire. Race compound tires have several "activator"
chemicals in them and get set into motion with heat. Getting the tire
hot quickly actually spends or wastes some of the chemicals and tires
will lose grip sooner than if warmed slowly on a warmer.
