The tires were purchased last summer and put in use late last fall. My bike is kept in a dimly lit garage and I only ride from late spring to end of fall, so really don't know why both tires are doing this so quickly.

However, it's not of any concern, since the rubber is just a cover over the tires structure. The only issue may be that over time, the bond between the tread rubber and tire body will weaken, allowing the tread to break off in pieces. That doesn't happen overnight, and progresses slowly so you have plenty of time to decide when you want to call it.
Those of riding high end tubulars are used to tread separation on old tires, and learn to glue it back down with rebber cement.
I weight 160lbs and pump my tires up to 120psi every ride. They are rated for 110-160psi... Should I have pumped them up higher.
All in all I will be picking up spares when my saddle comes back in stock. Ill just keep an eye on these
