I have 3 sets of the green compound left over from the 2007 IIC. I was looking for the temp numbers on the jaco website, but they only had shore number which are more for firmness....right?? haha The green dots are 28 shore. Ive tried these tires at parking lot races because my Sorex 36's end up working better. Id really want to know the temperature rating of these Jaco tires. Hmmmmmmmmmmm???
