I use Contiental GP 4000s tires and Coni Race tubes for racing. I've always pumped my tires up to a pressure of 120 psi for my Zipp 808's. I was told recently that I should have the psi around 100. Reason being to limit vibration to be more comfortable and run better of the bike. The tire conforms better to the ground at 100. At 120 the tire will roll over everything.
Any truth to this?
