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 RPM (10 to 15 mph with recent high sensitivity sensors) or higher, 300 RPM (55 to 60 mph with typical low sensitivity sensors), and forces of unbalance are measured by sensors.

3. Tire uniformity - Wikipedia

   en.wikipedia.org/wiki/Tire_uniformity

   The standard test speed for tire uniformity machines is 60 r/min of a standard load wheel that approximates 5 miles per hour. High speed uniformity machines are used in research and development environments that reach 250 km/h and higher. High speed uniformity machines have also been introduced for production testing. Machines that combine ...

   en.wikipedia.org/wiki/Balancing_machine

   A balancing machine is a measuring tool used ... volume and high-precision balancing tasks. The latter being required when the rotor has a high service speed, or ...

5. Merrill Wheel-Balancing System - Wikipedia

   en.wikipedia.org/wiki/Merrill_Wheel-Balancing_System

   The Merrill Wheel-Balancing System was the world's first electronic dynamic wheel-balancing system. It was invented in 1945 by Marcellus Merrill at the Merrill Engineering Laboratories, 2390 South Tejon Street, Englewood, Colorado , and is now recorded on the list of IEEE Milestones in electronic engineering [ 1 ] and as an American Society of ...

6. Tire manufacturing - Wikipedia

   en.wikipedia.org/wiki/Tire_manufacturing

   Tire balance measurement is a test where the tire is automatically placed on wheel halves, rotated at a high speed and measured for imbalance. Large commercial truck/bus tires, as well as some passenger and light truck tires, are inspected by X-ray or magnetic induction based inspection machines, that can penetrate the rubber to analyze the ...

7. Radial force variation - Wikipedia

   en.wikipedia.org/wiki/Radial_force_variation

   Radial force variation or road force variation [1] (RFV) is a property of a tire that affects steering, traction, braking and load support.High values of RFV for a given tire reflect a high level of manufacturing variations in the tire structure that will impart ride disturbances into the vehicle in the vertical direction.
