Road Bicycle Tire Pressure Calculator

Optimizing Your Tire Pressure for Your Weight: A recent article by Ann Heine in Bicylce Quarterly discussed the need for optimum tire inflation. The article starts off by saying "Inflating your tires to achieve 15% tire drop will optimize your bicycle's performance, comfort and handling."

The calculator on this page produces the same PSI measurements as the chart. Hope you like it.
