These three pictures show a bad weather check and two minor ones in a 3 year old nose tire on a Tiger.  Tires are inflated to the max airframe pressure and then examined, in this case I used 30 psi.  The large one was visible without air, but upon filling the two others came into view.  New tire time.  Most likely, sat flat a bit in one spot.  All of these cracks are within 6 inches of the rim of the tire.
