If glass went through the kevlar and all the fancy flat deterrents on the Bontranger Hardcase Race Lite tire...
No tire is completely immune to flats (other than solid tires, and you don't want those). I have Schwalbe Marathon tires on two of my bikes. I put over 5000 miles on those tires before I had a single flat, but it did happen.
I also run wider tires at lower pressures, which may help some.
When I first started riding, I bought one of the Bontrager Hardcase tires. I couldn't mount it on the rim. I took it back.
