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
