Method for evaluating tire self-cleaning capability by analyzing recorded images
First Claim
1. A method for evaluating recorded images of materials being released from a tire tread, the method comprising the steps of:
- rotating the tire tread about an axis;
recording images of the tire tread during said rotating step;
using the images from said recording step to determine when materials begin releasing from the tire tread during said rotating step; and
using the images from said recording step to determine when materials stop releasing from the tire tread during said rotating step.

Abstract
Methods are provided for evaluating the ability of a tire to release materials from its tread during rotation. A tire tread is rotated about an axis while images of the tread are recorded to capture the effect of centrifugal forces on materials that have been loaded into the tread. The images are then used to quantify the location of certain events during the rotation of the tire tread such as when e.g., materials first began releasing from the tread during rotation and/or the rate of such release. These events can be correlated with other variables such as the rpm, centrifugal acceleration, and/or time at which such events occurred. By comparing these quantitative results for different tread patterns, the effect of differences between tread patterns can be evaluated to develop and improve the self-cleaning ability of a tire.
