Swapped out all the airless for SMPs and now have had over 10,000 combined commuting/utility/training/recreational miles on 3 different sets w/1 flat and 1 slow leak(both on the same tire). Since the slow leak developed I replaced the tire w/a new SMP and have well over 1000 miles on it w/no issues. The front tire is fine w/over 8000...plenty of tread left.
Mirrors my experience. I've commuted daily for 11 years in Iowa and Heidelberg, Germany on Schwalbe Marathons (NOT Plus) @700X47mm (622-47) and Schwalbe Tubes. Approximately 55,000 miles with zero road side flats and perhaps 8-12 slow leaks that developed either at home or while at work. Only have to top up the air pressure every 3rd or 4th week.
