Bicycle Tire Low Rolling Resistance. The main reason for the loss of energy is the constant deformation of the tire. For many years narrow 23mm tires have been the standard width for road bike tires.

42 5 kg 94 lbs rr 12 psi 0 8 bar rolling resistance at 16 psi 1 1 bars single tire speed.
Rolling resistance at 8 psi 0 6 bars single tire speed. 42 5 kg 94 lbs rr 16 psi 1 1 bar rolling resistance at 20 psi 1 4 bars. There are a number of factors that contribute to rolling resistance. Originally low rolling resistance tires were made with a hard rubber compound and stiff sidewalls to reduce friction and flex.
