Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
Micro fractures or checking is common and normal on tires, and nothing to worry about. As you ride, the tire flexes, and the rubber which may be hardened bu UV, ozone, or just age will do that. It doesn't matter, because the rubber is only there for traction and as physical protection for the fabric underneath which is what provides the strength.
BTW- the 1500 mile figure is meaningless. Tires age over time and miles. Time is probably 5-10 years on average, and mileage until the tread wears through to the under layer, which happens when it happen, not at a fixed distance.
