The Small Block Eight is a good choice,its one of the fastest rolling tires for a trail but has no flat resistance.Myself and friends use them.Many of the younger dudes convert their tires to tubeless.No more flats.Remove tube and add a product called stans tubless kit.As far as flats go I'm due its been months for me.Last year I had 13 flats in 6 weeks Mtb and road.Screws ,tacks,nails road bike and thorns for the mtb.The thorns can be very hard to find.Remove tube and rub fingers inside of tire,you will feel a slight nub that will be it .Hard to even see with the eye, especially mine.
