Glass Transition Point Compound Standards?
I was reading a description of a new tire and came across this odd phrase. Does anyone know what "glass transition point compound standards" are?

My gut reaction is it's the temp at which the rubber melts. As in, they don't have any Death Valley burnout contests in Japan.

In layman's terms, A glass transition temperature corresponds to a phase change where the material becomes more rigid and ordered. For tyres(rubber) I guess this would be the point where (below the Tg) they become much stiffer and lose some of their grip.......

Would there be any reason why the US would have different standards for Tg in tires than Japan?
Different Tg standards could be related to different climates (total shot in the dark). If you live in a generally warm climate then you may be able to get away with using a compound which has a slightly higher Tg ??
