Just curious-

Do you routinely inflate your road bike tires to 120 psi? I do and they're hard as a rock. I thought I read somewhere that when you're riding there should be a small bulge from the back tire - when my tire is at 120 psi there is very little/no bulge at all.

Do you think there can be a drawback to inflating to 120? I've had my share of snakebite flats when my tires are underinflated (pure laziness on my part!!).

Thanks
