  2. Low rolling resistance tire - Wikipedia

    en.wikipedia.org/wiki/Low_rolling_resistance_tire

    A 2003 California Energy Commission (CEC) preliminary study estimated that adoption of low-rolling resistance tires could save 1.5–4.5% of all gasoline consumption, but that current data were also insufficient to compare safety and other characteristics.

  3. Rolling resistance - Wikipedia

    en.wikipedia.org/wiki/Rolling_resistance

    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.

  4. SAE J2452 - Wikipedia

    en.wikipedia.org/wiki/SAE_J2452

    SAE J1269 and SAE J2452 performed on new tires. SAE J2452 is a standard defined by the Society of Automotive Engineers [1] to measure the rolling resistance of tires. [2] Where the older standard, SAE J1269, produces measurements of rolling resistance under steady-state (i.e. thermally equilibrated) operating conditions, SAE J2452 produces measurements during a transient history of speed that ...

    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.

  7. Motorcycle tyre - Wikipedia

    en.wikipedia.org/wiki/Motorcycle_tyre

    Rolling resistance is the resistance that occurs when a tyre rolls on a flat surface. The rolling resistance coefficients of motorcycle tyres are about 0.02. [ 1 ] It tends to increase with forward speed and decrease as inflation pressures increase.
