Tire Pressure Settings Bible

Riding several tires as well as compounds over the years, I decided to write some of the optimal tire pressures that I felt worked the best in a variety of conditions. Here are five major brands and their pressures, that I thought could be some benefit to you. If you're wondering what PSI to run in your new tires, look no further than the tire pressure bible below. Yes, you will see that some soft terrain tires are still categorized under the “Intermediate/hard Terrain”. That is because some soft terrain tires have an optimal feel in intermediate conditions. These tire settings are for: 80/100-21, 120/80-19, 110/90-19, 100/90-19, 120/90-19.
