ASTEC® PLUS Tire Evaluation Center (Akron Standard® Tire Evaluation Center)
The ASTEC® PLUS tire evaluation center measures tire uniformity for passenger and light truck radial tires.
Force Variation is a tire behaviour that creates ride disturbances such as vehicle vibration. Radial force variation induces forces into the vehicle on every tire rotation. These forces are amplified by the vehicle’s suspension when the forces occur at the vehicle’s natural frequency. Lateral force variation also creates vibration and steering pull.
Runout is a measure of the “out-of-roundness” of a tire. Radial and lateral runouts also cause ride disturbances during each tire rotation.
Sidewall Appearance is the visual quality of a tire, which is influenced by several tire construction features, such as sidewall splice, body ply spice, and component quality. When splices are overlapped they can create a depression in the sidewall when the tire is inflated. When splices aren’t placed together correctly they can cause a bulge. These defects are not acceptable to the consumer.
ASTEC® PLUS has the best measurement repeatability of any machine in the industry. This means that there is very little measurement error. When more tires pass grade limits, factory yields increase.
The ASTEC® PLUS is designed maximum access to the machines main components while also keeping the operator and bystander’s safe.
