Title:
BEAD CLAMPING FORCE PREDICTION METHOD, TIRE MANUFACTURING METHOD, AND TIRE
Document Type and Number:
WIPO Patent Application WO/2022/176269
Kind Code:
A1
Abstract:
This method is for predicting a clamping force BF of a bead part 4 of a tire 1 having bead cores 5 in the bead part 4. The method includes a step for using a mathematical formula to predict the clamping force BF of the bead part 4 when the tire 1 is fitted to a rim R of a wheel. In the predicting step, the bead clamping force BF is predicted by using the inner diameter IDw of the bead core, the rim diameter ODR, and the thickness Ct of a tire radial inside which is further inside than the bead core 5.
