A Run Flat Tire for Improving Durability at Zero Pressure

摘要

The present invention relates to a run-Pratt Thai to improve the running durability in the absence of air pressure the shear stress to be concentrated on one point of gulsin area to optimize the shape of the gulsin region of the run Pratt Thai by dispersing in a large area of ​​the sidewall.; Run flat tire having improved puncture during running durability in accordance with the present invention by distributing the shear strain in the stress concentration area By placing the convex shape of the oval towards the inner side in the up gulsin region of the sidewall inner increase the puncture during the running durability of the tire to have its features.
