Dorky pants R us - Bike tire pressure calculator

A tool I found where you can calculate the ideal tire pressure for your bicycle. The ideal tire pressure varies greatly depending on the tire width and the rider weight, with this tool you can calculate it very accurately.

It also helps you to chose the correct tire width, since it also depends on the rider weight, but the website probably describes it better than I can do it: "If calculated pressure exceeds tire’s rated maximum, choose a wider tire. If calculated pressure is below tire’s safe minimum, choose a narrower tire."
