I just put a new set of Carlisle F1 8x16s on my 2400. I too noticed what you are describing along the center line of the tire, chunks about an inch across on the leading edge of several of the lugs. This occurred after I ran a few 800# round bales down a country road: (small) rock embedded in asphalt (the way country roads are maintained in TX.) all weather road. The tires were obviously (opinion) recently vulcanized and apparently had not been subjected to Ozone damage (opinion) like tires I had on the 6530 when I purchased it new.....which had the concentric rings emanating from where the lug emerged from the main carcass made by Titan....on brand new tires....which didn't shed lugs of rubber when subjected to much higher loads on the same road surfaces.
Soooo having had both, (not being a tire manufacturing person) I'd assume the amount of "Plasticizers" incorporated into the tread determine how soft is the tread and being softer is more prone to chunks being torn off by road surfaces and such, but not cracking, not having been exposed to the sun sitting out in the back lot where new tractors are received (minus tires and wheels) and the tires and wheels are added. (Ref. Google Maps of Rome, Ga, Branson headquarters back lot.)
