Probably one of the more reviewed tires on the web, so be sure to check out Amazon, REI and Buzzillions. I have the 28 Ultra Gatorskins that you are interested in and like them a lot. I've had Bontrager Race Lite Hard-Case, and Serfas Survivor Series as well. All good puncture resistant tires. The Gatorskins are a softer tire as compared to the others and rides a bit smoother. It may be this aspect that some experience the tire "picking up" little pieces of glass, etc. But it is good practice to regularly inspect your tires before riding anyway, and with a simple razor, pull out the suspecting culprit.

As far as tire pressure I admit I go above the 116 rating. PSI is not absolute and there are many articles written about that. I'm not abusing the tire and raised the psi incrementally. I weigh 250 too, so that has some influence as to why I go above, but mostly it's preference. I'm wondering what others that go above the stated PSI pump their tires up to?
