The predominate rubber type is still SBR and is cross-linked. So it doesn't remelt and recycling is not really an issue. there have been efforts to grind up the rubber into little pieces and incorporate them into a rubber or plastic matrix, but the cure packages used in SBR smell and it has seen little success.

I think much of the refusal of chain stores to mount old tires and the use of DOT codes was because the failure of aged tires was recognized, not just that it started happening when it didn't before. Perhaps a side effect of lawyer proliferation after that.
