Graves Motorsports Motorcycle Tire Warmers. These are the newest spec tire warmers from Graves Motorsports. Fresh off 4 straight Superbike Championships with Josh Hayes and Josh Herrin on the Graves 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.
Rear tire fitment : 180 - 195 Front Tire fitment : Fitment 120. Pricing includes both front and rear tire warmers. This item includes a nylon carry bag.
Note: Our warmers are SPEC for 120 volts power sources at those setting the warmers will heat to 80c within 30 minutes. Generator requirements are 1050 watts (set requires 1200 continuous) - at those settings 80c will be reached in approximately 45 minutes.
Chuck Graves team owner and former Champion himself has this to say about the Graves warmers.
"We developed 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 Elements
• 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 away
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 simply avoided.
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.
