I 'm in the same boat. Been looking at some softer tires for better traction, but have been concerned with wear. I was at the St. Joe Nat'l Enduro here in Missouri, and looked at a fellows S12's after the race. I was amazed at the condition of the tires. No chunking at all!!!! and St. Joe has alot of nasty rocks. This alone sold me on which tires too get for my 220.
