Tire cracking is the result of breakdown of the chemical bonds in the elastomers that comprise tire rubber. Exposure to UV light (sunlight) and ozone are the biggest contributors to this chemical breakdown. However heat, exposure to other chemicals etc. will also speed the process.

I suspect the reason tractor tires seem to be more prone to cracking more than other tires is tractor tires are in service much longer than your average car or truck tire. Case in point: With the exception of the rears on my Super M, there's not a tire on any of our 7 tractors is less than 20 years old. Most have been on for 30+ years. (When was the last time you saw a car that's had the same tires on it for 30 years?!) Another case in point: A buddy of mine has a Ford 8N his father purchased new in 1948. The little Ford has lived in a dry, unheated shed it's entire life - for last 40 years or so it's been out only to push snow. The tractor's still on all 4 original tires - they're getting kind worn and shiny, but still show only minor cracking.
