Hi Fernando_G:
___Bad luck pure and simple unfortunately … I know of a few Insighter’s using its stock OEM, extremely LRR, pressed up to 50 + #’s, who have gone well over 50,000 miles let alone Rick Reese who is at 130,000 miles and still has at least one OEM still on his car! I know I am not talking about the Bridgestone and Dunlop’s of the HCH but the same discussion applies.
___By chance does your commute take you though an area with a lot of construction of homes, highways, or buildings etc.? Road debris around such areas could be a cause of continuous flats. A bent rim could also cause a tire to go flat due to incomplete seating of the tire bead to the rim but the tire place you have had your HCH serviced at should have spotted that in a millisecond. Ask them next time just in case they have a new guy at the rack un-installing and re-installing tires … He should have found the piece of debris that made your tire go flat as it (whatever it is) is usually still stuck in the tire when they repair it. The will usually show you what you ran over and where in the tire they found it.
___Good Luck
