NY mud :-)
The only time that I've cracks developing in the valleys are
tires which have not been in use for years ... tire compound hardens
up and dries out.
The only thing that I can think of is maybe excessive heat build up
followed by a sudden cooldown.
I would not do hiway speed driving on them for too much longer.
