What tire and tire pressure you choose can have a huge impact on your speed. In this video I sit down with Josh Poertner of Silca to discuss how to determine the optimal tire pressure, what makes a tire fast or slow, and whether or not tire inserts increase rolling resistance.

Find your optimal tire pressure with the Silca Professional Tire Pressure Calculator:
