If you don't like picking sharp things out of your tires you can try to find some of the tire dragging gizmos that were popular with some riders in the '70s. Not sure what these were actually called, but they involved a curved, flattened piece of wire that lightly drags over the surface of the tire; they are mounted on the brake bolts. The theory is that the first time an object gets wedged in the tire it has not been pounded in sufficiently to puncture and can easily be knocked out. These were even sort of gauche then, but many riders in my area swore by them.

Maybe we could make a new version in titanium or carbon fiber?

if i suspect that i've just run over glass, i just reach down and let the knuckles of my gloves rub along the center of both my tires. i'm not sure if i've ever knocked anything out of there, but it gives me peace of mind.

--Has anyone invented retractable brushes to remove sharp debris from bike tires while on the fly?
There used to be a product called "Tire Savers" which were wire scrapers designed to glide a fraction of an inch over the surface of each tire. The idea was to knock off the road debris before it got pushed into the tire on the next revolution of the wheel.
--Any new developments in that direction?
