Unfortunatly they heat the tyres from the outside so the external temperature of the tyre gets heated to a greater temperature than the internal parts of the tyre, this i would suggest causes greater deterioration. Tyres used during a race will easily achieve temeratures of over 100 celsius and from what i understand it is only above 105 degrees that the tyres really start to deteriorate.
If i could heat the tyre from the inside you would get a constant overall temperature which would produce less tyre wear and a more consistant heat.
The problem with heating inside out is the poor thermal conductivity of rubber. It will take too long for racing. If iron powder can be added to the formulation, your idea may work by improving conductivity.. Alternatively heaters like those used for defrosting wind shields can be embedded into the tyre. Who knows? One can design these to be multipurpose, like radial reinforcement as well.
As an aside, rubber deteriorates even at lower temperatures.
