I have Bontrager race lite hard cast tires and so far they have been pretty bombproof.
As far as I can tell, the only thing I could have run over was a small rock...didn't see any glass/nails/etc. on the road. And I wasn't even going at high speeds...just messing around with clipping in/out of my new pedals in a quiet neighborhood. The tire in question was the rear tire and the blowout was on the side of the tire. And, yes, they were properly inflated.
