View Full Version : Tire warmer thermostat



03-09-2004, 11:49 AM
Such a simple concept, but so expensive to buy aftermarket. After looking at Gordon's Pole Position Chicken Hawks at the last RS trakc day, I decided that it was high-time to build my own tire warmer thermostat. Here's the basic write-up. It's too ghetto-fabulus to not give away, I might come up with a "production" version using better components if there's interest. Here's my basic setup...

It's currently licenced under http://www.perforce.com/perforce/co...open_source.pdf Replace "software" "hardware"....you get the idea

Basically, go get a hot water heater bottom thermostat, 12' of electrical cord, two male two-prong plugs, and two female two-prong plugs. Build two 6' extension cords from the wire and plugs. Take one of the extension cords, and seperate the wires. Cut this wire in half, and strip 1" of insulation off the end. Wind one end of the wire around each terminal of the thermostat and secure wire with screws in thermostat. Coat the terminals with silicone or epoxy. Plug one end of this contraption into the wall, the other into your warmers. Tuck the thermostat under your warmers, metal side down, and you now have an adjustable tire warmer thermostat.

Approximate cost (from Lowes) Thermostats : $10 each, wire : $6 total, cord ends : $2.50 each. total cost : about $35... Time : ~ 1hr.

inital tests seem to indicate sucess. they are definatly turning on and off with temperature changes. I tried it at the lowest setting (90 degrees) and it worked fine. going to test with 130 this eavning.

Just for an update, I tested these at TWS, and they worked great! Maintained a constant ~130degrees over the long lunch brake between my races.

here's a link with some pictures of the setup :
