Abstract

PURPOSE:To prevent the exfoliation of a belt part and improve the durability of the belt part by specifying the radius of curvature of a crown part, the ratio of variation amount of radius before and after the charge of air at a prescribed part, and the ratio of the variation amount of the concave of a belt layer, in a large-sized captioned tire for rough ground. CONSTITUTION:The radius of curvature of a tire crown is set within a range of 150-300% of the tire max. width. The ratio of each amount DELTAC, >=E of variation of tire radius before and after the charge of air pressure in the plane constituted of the tire equatorial plane L position and the average-value position of the width l1-l4 of the belts 6a-6d having the width at least 60% of the width l2 of the max. width belt 6b which is parallel to the equatorial plane L is specified to 0.5-0.95. The pat between the cross point 6h of the supposed plane M of the max. width belt layer 6b after the charge of air and the cross point 6j of the equatorial plane is formed concaved by DELTAB in the direction of tire axis, and constituted as follows: DELTAB>=DELTAC-DELTAE. With such constitution, exfoliation of a belt part is prevented, and durability can be improved.
