25-27 = 60 psi/4.1 bar
28-29 = 54 psi/3.7 bar
Medium Air Pressure
Pro DataPro 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.
