  2. Tire balance - Wikipedia

    en.wikipedia.org/wiki/Tire_balance

    In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 r/min (about 5–7 m/s (18–25 km/h; 11–16 mph) with recent high sensitivity sensors) or higher, 300 r/min (about 25–27 m/s (90–97 km/h; 56–60 mph) with typical low sensitivity sensors), and forces of unbalance are ...

  3. Tire uniformity - Wikipedia

    en.wikipedia.org/wiki/Tire_uniformity

    Tire uniformity refers to the dynamic mechanical properties of pneumatic tires as strictly defined by a set of measurement standards and test conditions accepted by global tire and car makers. These standards include the parameters of radial force variation , lateral force variation , conicity, ply steer, radial run-out , lateral run-out , and ...

  4. Electromagnetically induced acoustic noise - Wikipedia

    add some glue (e.g. a layer of glue is often added on the top of television coils ; over the years, this glue degrades and the sound level increases) change the shape of the coil (e.g. change coil shape to a figure eight rather than a traditional coil shape) isolate the coil from the rest of the device to minimize structure-borne noise

  5. Tire bead - Wikipedia

    en.wikipedia.org/wiki/Tire_bead

    Tire bead is the term for the edge of a tire that sits on the rim. Wheels for automobiles, bicycles, etc. are made with a small slot or groove into which the tire bead sits. When the tire is properly inflated, the air pressure within the tire keeps the bead in this groove. Reducing tire air pressure is a frequent practice among off-road vehicle ...

  6. 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]

  7. Skid (automobile) - Wikipedia

    en.wikipedia.org/wiki/Skid_(automobile)

    A burnout is when a car intentionally locks the front wheels to hold the car in place while spinning the rear wheels. The dynamic friction of the spinning tire against the road causes significant amounts of the tire's rubber to be deposited onto the road surface, and increased temperature from friction usually creates dense white smoke.

  8. Camber angle - Wikipedia

    en.wikipedia.org/wiki/Camber_angle

    However, due to the weight transfer inherent while turning, the outside wheels bear more of the force of turning and negative camber will improve handling overall. Caster angle will also compensate for this to a degree, as the top of the outside tire will tilt slightly inward, and the inner tire will respectively tilt outward. However, any ...

  9. Tire rotation - Wikipedia

    en.wikipedia.org/wiki/Tire_rotation

    Many tire manufacturers say that tire rotation is no longer necessary, except to ensure that best tires are fitted at the rear of the vehicle. [5] In practice this means that when the front tires become worn, the new ones should be fitted to the rear, moving the old rear tires to the front. Best tires on rear of vehicle
