Chunking happens when a fully treaded tire overheats, and chunks of the tread separate from the tire. Blistering is when a racing slick tire with no tread overheats, and the "tread" (which is not in fact treaded) develops blisters.

Sorry but the picture in the OP post are tread blisters that have pealed. Blister are areas where the layers in the tires construction separate most often from over heating. They can happen in a treaded or un-treaded tires. Looks the same to me, and the OP post show gravel graining from cooling down while still rolling on the asphalt

That picture doesn't look the same to me. I agree with Racer, the 3 pictures by the OP look like the rubber is worn through to the carcass. Look at the strip of heavy wear on the outer edge. Chunking usually happens with taller tread blocks overheating, his tires don't have any grooves or tread left where the damage is located.
