Haven’t looked at this in a while and am trying to figure out recommended pressure for Conti II with Zipp 2015 808 firecrests (latex tube if that makes a difference). 175 lb rider.

Thanks all.

All jokes aside, optimal tyre pressure is determined by your weight and the tyre width, the brand/model of tyre is irrelevant.

Having said that, Michelin and Vittoria have recommnded tyre pressure charts that give very different answers. Personally I much more inclined to follow the Michelin chart, I think the Vittoria way overstates the optimal pressure.
