Tire Rubber Melting Temperature

The air pressure in tires increases as the temperature goes up.

Tire rubber melting temperature.

Scientists have figured out that for every 10 degrees fahrenheit that the temperature rises the tire pressure will increase by one pound per square inch psi. The rubber in tires is vulcanized meaning that is in fact one big molecule. When heated to a high enough temperature in an inert atmosphere away from air oxygen the rubber will decompose sometimes partially resulting in an oily ooze. 107 124 349 polyethylene hd.

220 268 432 488 polyethylene ld. Total tire recycling using proprietary and patented process. There is not a single melting point for these substances so using the term softening applies more closely to the super heating of rubber tires. The rubber used in creating tires is a mixture of many compounds including carbon latex rosin and chalk hardened by the addition of sulfur and other compounds.

At ambient temperature old tires can be turned into crumb rubber. Tire temperatures are the easiest and most cost effective link you have to the action at the tire contact patch. Using the tire temperatures effectively can pay considerable dividends on the race track and it s worth the effort to learn what they mean and how to adjust setups accordingly. Rubber begins to melt at approximately 180 degrees celsius.

At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization. It doesn t sound like much but there s typically only 30 35 psi in the tires of passenger vehicles. Melting points and ignition temperatures. The optimum temperature for rubber is 20 c.

10 chassis tuning tricks using tire temperatures. A common method is to chop the tires into half inch pieces and mix the pieces with liquid nitrogen at a temperature of minus 148 degrees fahrenheit minus 100 degrees celsius. It will not melt.
