Tyres degrade over time and some things make them degrade quicker such as UV and Ozone, but heat cycles also contribute to this degredation. I think the on a molecular level cross linking occurs between the long chain polymers. However, you could use tyre softener solution to reverse it. It does work as I had a set of really hard inlet rubbers which when soaked for three days come out quite soft.

Its one of the reasons some use tyre warmers and leave them on,to reduce the amount of heat cycles the tyre goes through and extend there life.
not really something to worry about with a roadbike as they arent subject to high temps like the track produces.
