Tires...Tires...Tires?

Heat is what causes everything to disintegrate including tires,. When rolling the tire has to change shapes from round on the top to flat at point of contact and actually goes to a wave pattern after contact with the road. The constant flexing is what causes the majority of the heat generated in the tire. It WILL eventually fail. The higher the speed, the more dramatic the failure. Even old tires kept "from the elements" are still "old". The chemical compounds used in the manufacture of the tire are in a state of deterioration from the time they are made and start to harden reducing ease of flexibility. Take any matreial and flex it back and forth and you will see that the stiffer the material the quicker it will get hot. Just like us, we start to die as soon as we are born...
