Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.
[40] [41] Road racing tires with different tread compounds for the front and rear have been developed, thereby attempting to provide more traction in front and less rolling resistance in the rear. [42] Pattern. Treads fall somewhere along the spectrum from smooth or slick to knobby.
[clarification needed] The approximation can be used with all normal coefficients of rolling resistance . Usually this is assumed to be independent of (speed of the bicycle on the road) although it is recognized that it increases with speed. Measurements on a roller-mechanism give low-speed coefficients of 0.003 to 0.006 for a variety of tires ...

There are a number of variables that determine rolling resistance: tire tread, width, diameter, tire construction, tube type (if applicable), and pressure are all important. Smaller diameter wheels, all else being equal, have higher rolling resistance than larger wheels. [49] "Rolling resistance increases in near proportion as wheel diameter is ...
In a non-scientific study (I looked at tires available from a national chain that fit my car), 85 percent of LRR tires had an “A” rating for traction, compared to 87 percent of Non-LRR tires.
