Use a hotbox and warmer?

[ShaneRedline]

Going to be racing indoors, about 36 degrees temp this weekend. So keep tire warm, like what temp in the hot box? Then put tires on and go to grid, put tire warmers on Until at the grid?

Who's sells tire warmers

Shane,
Chicken Hawk has tire warmers with adjustable temp.

With a hot box, keep the tires 80-120* and watch how quickly the temps drop before you hit the track. While getting the tires up to that temp might be an advantage for a lap or two, you will see the tires lose psi considerably as they lose temp after just a couple laps -- that loss in pressure will cause all sorts of issues. The amount of time it takes for the tires to cool will be somewhat constant -- the time it takes for your class to go on the track is never constant (cautions, etc.) The tire warmers will also hold heat even when unplugged to a certain extent -- leave them on the tires until the last second. Again, really watch your air pressures and how much drop you get from the temp you set the tires at to the actual race temps.
