Official Tire Warmer of the F1K Series sanctioned by SCCA PRO Racing
Road Racing drivers know that they benefit from Tire Warmers to get a good start to the race. However a Tire Warmer provides the ability to tune and manage tires in the paddock for several important reasons:
- Go Fast from the Green Flag
- Set Hot Tire Pressures in the Pits
- Choose the proper compound to last the race
- Save "Heat Cycles" by keeping tire warm in between sessions
- "Heat Cycle" tires BEFORE you get to the track
Hot rubber grips the track surface better since not only does the co-efficent of friction increase, but the Tire’s ability to form the track surface through "mechanical keying" is increased
Set Hot Pressures
CHR Tire Warmers will get your tires surface AND carcass into the proper temperature range (same as you’ll see on the track). 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
Choose your Compound
When selecting which dry compound tire to run, the tire warmers can open up some options. For example a driver is torn between two compounds; tempted to use the softer one for the grip in the early laps, but concerned it may not make it race distance. By using the tire warmers the harder of the two choices can be used so that no disadvantage is present during the opening laps and the tire will last the entire track session or race.
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 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 can be increased
"Heat Cycle" at home
Many tire brands recommend heat cycling the tire and then waiting a period of time before using the tire again (usually 24 hours). This assists in having the same compound tire be more durable once the chemicals become active and the tire is more "settled" on a molecular level. Tire Warmers let you perform "heat cycles" at your shop prior to leaving for the track.
