Bicycle Tire Pressure And Rolling Resistance. Rolling resistance at 120 psi 8 3 bars single tire speed. Traditional wisdom says that higher tire pressure equals lower rolling resistance because on a smooth surface hard tires flex less and create a.
The results presented here assume that the tires are kept at 100 psi 6 9 bars. Traditional wisdom says that higher tire pressure equals lower rolling resistance because on a smooth surface hard tires flex less and create a. Rolling resistance at 120 psi 8 3 bars single tire speed.

The results presented here assume that the tires are kept at 100 psi 6 9 bars. A tire s coefficient of rolling resistance crr refers to the power cost of the tire and inner tube if used. Rolling resistance does vary slightly with tire pressure but it s not linear and it depends on the surface. In general rolling resistance with a road tire 23 to 28mm wide is at a minimum somewhere in the range of 80 to 120 psi about 6 to 8 bars on most roads with most tires for people of most weights but it s very hard to say what is the ideal pressure.
