On my Lesco 54" hydro from time to time I`ll throw on the ole sulky .This last season I had two flats within a week on the sulky tire. I slimed it & it went flat again. Maybe I put the stuff in improperly. Brought home a new Flatlander last week and picked up a shiney little thumb-tack dead center on my brand new units` front tire. Are there different tire products or they all about the same? Or maybe I don`t even want to go with those tire additives.I live out so it ain`t like I`ve got a tire shop next-door.Like to hear some thoughts from the pro-cutters and resolve this problem.
