  2. Low rolling resistance tire - Wikipedia

    en.wikipedia.org/wiki/Low_rolling_resistance_tire

    Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.

  3. Tweel - Wikipedia

    en.wikipedia.org/wiki/Tweel

    Although it is acknowledged that the initial prototype automotive Tweel tires did demonstrate flaws with regard to noise and high-speed vibration [5] and produced 5 percent more friction compared to a radial tire, [3] these early issues were resolved in subsequent prototypes and, in 2013, automotive Tweel prototype products had been shown to be ...

  4. Roadway noise - Wikipedia

    en.wikipedia.org/wiki/Roadway_noise

    Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]

  5. Soundproofing - Wikipedia

    en.wikipedia.org/wiki/Soundproofing

    Vehicle soundproofing can reduce wind, engine, road, and tire noise. Vehicle soundproofing can reduce sound inside a vehicle from five to 20 decibels. [21] Surface-damping materials are very effective at reducing structure-borne noise. Passive damping materials have been used since the early 1960s in the aerospace industry.

  6. Noise control - Wikipedia

    en.wikipedia.org/wiki/Noise_control

    Highway noise is today less affected by motor type, since the effects in higher speed are aerodynamic and tire noise related. Other contributions to the reduction of noise at the source are: improved tire tread designs for trucks in the 1970s, better shielding of diesel stacks in the 1980s, and local vehicle regulation of unmuffled vehicles. [13]
