I've ridden nearly 1000 miles on my fatty this year (Carver O'Beast- carbon fork), over half of that mileage has been non-snow riding on rocky, rooty New England ST. Not sure what your locals are doing wrong, but I'm a fairly aggressive 230 lb rider, running 8-9 lbs pressure in my Lou front, Nate rear TUBELESS on Marge Lites and haven't had a flat yet this year.
