i use a mag glass, flashlight and dental pick every night on my tires, usually remove about 2 or 3 small pieces of glass a night.
glass is tough, it will not break down into little pieces and leave the tire. it will continue it's journey inward until it's mission has been completed, which is to get a cab out to your location for a ride back home.
keep an eye out for more glass because it's a comin. but if you get it at an early stage, it will end up down at the dump where it belongs.
i gotta try this superglue thing to see if it will bond to a gatorskin hardshell,
