Rolling Resistance Real tire width in mm: 22-24 = 88 psi/6.1 bar 25-27 = 80 psi/5.5 bar 28-29 = 72 psi/5.0 barHigh Air Pressure (80 psi / 5.5 bar)	8.3 Watts CRR: 0.00249
Rolling Resistance Real tire width in mm: 22-24 = 66 psi/4.6 bar 25-27 = 60 psi/4.1 bar 28-29 = 54 psi/3.7 barMedium Air Pressure (60 psi / 4.1 bar)	Pro Data
The Road Bike section is a multi tire size section, air pressures have been adjusted to the measured casing width. All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs. Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.
