I used the regular (HS 270 , HS 308 and whatever they are now designated) Marathon 47-622 tires to commute daily year round from 1998 to 2012, when I retired. I averaged 5000 miles a year and occasionally (once or twice a year) I did get up in the morning or leave work at the end of the work day and find the tire flat from a slow leak, but NEVER had an on the road flat while commuting. I still ride with regular Marathon tires about 2500 miles/year around town and still have had the same great almost flat free service. The front tires are good for about 15,000 miles, the rear about 5,000.
