Summary: The Virtual Elevation or Chung Method is based on physically sound concepts. In practice, however, tests using this method have produced unreliable results. Attempts at validating the method have failed to reproduce the claimed precision. A possible explanation: Testers ‘guess’ initial values for rolling resistance (Crr) and aero drag (CdA) as they… read more

When we developed version 3.0 of our Tire Pressure Calculator, we worked with the engineering department at Cal Poly Pomona to measure how much tires deflect under different loads and tire pressures. We repeated those measurements for many different tire widths and casings, creating the largest dataset of tire behavior to date. We… read more

A few months ago, we asked you whether you wanted all-black Endurance versions of our tires. You answered with a resounding “Yes!!!” Our crowdfunding met its goals for all models we offered—which means all models that could fit into our production schedule. Thank you for your support! (As an aside most of our road… read more
